HTML 5 to the H1 debate rescue?

A couple of days ago over Twitter I asked what people’s opinions were on the use of a website name as an H1 in pages and opinions on the use of multiple H1’s within a page. Without knowing it, the day before I tweeted this, a poll had been launched asking what do you use an H1 for? Like microformats versus accessibility and layout tables versus CSS , these types of debates tend to raise their heads every once and a while confirming that opinion is splintered.

Part of the reason why this debate doesn’t seem to be reconciled is because neither WCAG 1.0 or WCAG 2.0 explicitly say (either in the normative or supporting documentation as far as I can see but do double check) that using the site name as an H1 or multiple H1’s are not allowed. There’s probably good reason for this as there may well be edge cases where it makes sense but it does concern me when I see multiple H1’s on a page or the website name being used as an H1 on all pages in the website. To me it’s always been clear that the main heading of a page should be the H1 and not the website name and multiple H1’s should be rarely, if ever, be used. I’m not setting out to answer these two questions but thought them worth airing again to see if our collective thinking has moved on and if there is anything that can be learnt from it.

What’s all the fuss about?

So what’s the issue here, why do we need headings? Structure of a web page is needed for software such as screen readers to parse information so that users can both understand where they are in a page and also navigate between headings (h1 to h6). If you’re blind, for example, there are certain key strokes in screen readers that allow you to list the heading structure in a web page (a bit like a contents list) that you can in turn use to jump to where you want to go in the page. If no headings have been coded then all you are left with is text, images and form element information that is not neatly grouped in a way that’s understandable. It’s a bit like reading a newspaper with no visual headings – you’re left guessing where one section starts and another ends.

The image above shows a dialogue box listing headings in a page using the screen reader Jaws. A simple keystroke when on the page will pull up the dialogue box that the user can listen to and decide what heading level they want to navigate to.

Using the website name as an H1

The fact that the heading structure acts as a contents list of a page is a bit of a clue here. A page needs to be as logical and navigable as possible in order for the end user to access information and comfortably find what they want. As such I’d argue that, a page should only have one H1 and that it should be the heading of the page itself and not the website heading. The website name should be contained within the page TITLE in the HEAD of the document and of course can be reiterated in the logo or any other branding that exists on the page. You’ll no doubt have already spotted that under the hood of this site the template sets the site name as the H1 within all pages.

H1 coded around the site name and H2 around posts

This is a WordPress template and not my design (an HTML5 and WCAG 2.0 redesign is planned) however there are some interesting things to note here. On the home page of this blog, having the site name coded as H1 and post headings (with H3’s within them) coded as H2 make sense as the page structure flows logically. However when you move through the site to the About page, for example, this logic doesn’t follow through. Having the site name as an H1 doesn’t make sense as the natural H1 of the page is “About”.

So there is wriggle room it seems and possible edge cases for when the site name can be used as H1, such as on the home page, but in general however, I’d advise against this.

The SEO camp, often hit back with “But we want to have the site name as H1 so we can improve on our web page rankings”. I’m no expert on the inner workings of search engines but I’d argue that using the site name on each page as the H1 could in fact be damaging to SEO. As Andy Ronksley says, given the site name is already referenced in the TITLE the biggest boost you can do for for your rankings is use the  H1 to reflect the individual page and as such get the page indexed more accurately.

Using multiple H1’s within a page

I said above that there is “rarely” a use for multiple H1’s within a page. Generally speaking the page makes logical sense (to me at least but admittedly I only use screen readers to test pages) when it degrades gracefully from the site name in the page TITLE to the page name as the H1 and subsequent sections as H2 after that. As Jared Smith points out, if you use multiple H1’s when the user expects only one H1 there is a danger of missing subsequent content under the next H1 entirely.


With that in mind I have seen uses of multiple H1’s in pages where frames have been used to bundle related content. A supermarket website may want to have information about the aisle you are in, your basket, promotions and navigation all collected separately within a FRAME (an old school example but stick with me). If each of these FRAMES has a lot of content organised into it’s own hierarchy then it makes sense to perhaps use an H1 for each.

HTML5 and headings

While the H1 debate rumbles on there are interesting changes afoot in HTML 5 that could, in time, contribute to resolve the H1 debate. The draft new specification sets out to define areas of web pages with the introduction of new elements: <head>, <nav>, <article>, <section>, <aside> and <footer>.

Using HTML5, each element can have it’s own H1 and in turn, the hierarchy and nesting of each sectioning element determines the heading level of each H1. Looking at the example above, an H1 within the <article> will rank higher than the H1 in the <section> contained within it. This is not an entirely new concept as XHTML2 uses the <h> within sections however <h1> is see as equivalent as <h> in HTML5. These changes in HTML5 wont mean that heading levels as we know it (H1 to H6) become defunct, if that were the case all legacy content would simply fall apart after all. Instead, according to the current working draft of  HTML5, it is designed to be backwards compatible so that H1 to H6 are still supported.

Sections may contain headers of any rank, but authors are strongly encouraged to either use only h1 elements, or to use elements of the appropriate rank for the section’s nesting level.

A large benefit of using H1 for all first headings in sections in HTML5 is that it allows web pages to include content from other sources that already have a heading level defined. So for example blog posts can be listed in say a page listing all posts in one category or on the home page and the heading levels neatly realign themselves dependent on the hierarchy of sections in whatever page they are in.

This offers great benefits to developers and screen reader users alike. For developers it removes the headache of working out a heading structure (which can be complex and tricky at the best of times on large sites) and also saves on the headache of having to rethink structure if content is pulled in from elsewhere. For a screen reader user there is a stronger likelihood that a logical and useful heading structure is given.

However this is all theoretical on my part as support for HTML5 is only just starting out. Browsers are already building in support for HTML5 with Opera leading the pack however screen readers are trailing behind and are not participating in the W3C HTML5 Working Group. This should not prevent you, the page author from discounting implementing HTML5 (although for commercial projects I’d hold off for a bit). As the W3C Web Accessibility Initiative clearly outlines in it’s essential components of accessibility the user agents, authoring tool and web authors all play a part in accessible content each with their own responsibility.

One possible downside I can see is that search engines may not be able to index pages that have multiple H1’s. It’s not really possible to say at this stage but presumably search engines will instead work with the new section elements and their ordering within the page when ranking web pages.

I’m only just starting to find my way with HTML5 so may well have oversimplified the issues here. My colleague, Bruce Lawson has some excellent posts on his newly redesigned site using HTML5. In particular read about how headings and sections work together in HTML5, headings and accessibility. I’ll also be following up this post with looking into accessibility issues around HTML 5 and screen reader support as things evolve.

To wrap up

Navigating web pages using headings is essential to screen readers as WebAim’s recently published screen reader survey showed. What’s interesting to see is that while HTML5 may have serious flaws with regards to accessibility in other areas it may be working to support accessible content in others. What is essential to its success however is that  screen reader vendors step up and work to include support for HTML5 to complement efforts being made by browsers as well as the web development community. Hopefully then we may see an end to the groundhog day debate about H1’s (although I suspect another can of worms will be opened).

38 thoughts on “HTML 5 to the H1 debate rescue?

  1. Mmm I’m still not sold on multiple H1s (even in HTML5) because IMO we’re talking about a document hierarchy and not just accessibility. Think of styles in Word. It makes no sense to have documents with multiple H1s and I’m yet to really be pushed on the H1 – H6 limitation. Nearly always this conversation comes back to wanting to mark up the “logo” as a H1 in replication of the site name. Why replicate in the first place?

    But by having numerous H1s in different sections I’m wondering where H2 somehow stopped making sense?

    I see the heading hierarchy as a node tree, flip it on it’s head and it should have 1 root to make logical sense with relevant subheadings. Yes multiple H1s are valid but so are a lot of other illogical inaccessible or unthought of loopholes in the spec. A valid page isn’t an accessible page, for example. Similarly, a valid document hierarchy isn’t really a logical one right?

    I’m sure that the proper use of H1-H6 will be appreciated by Google and everyone else for being used informatively, as opposed to finding reasons to include even more H1s on a document regardless of the frames example. And, in all seriousness, the document as a whole needs to make sense, not just panels.

    But I think we’ll have to agree to disagree on this one. It just frustrates me that people seem to imagine H1 is a magic wand to wave at Google for SEO when all multiple H1s are really doing is complicating the document in the first place – like shouting at Google. We all shout, nothing makes much sense.

    How hard is it to write hierarchies anyway? (apologies for the rant)

  2. If you think of “h1” in HTML 5 as just “h”, it makes a lot more sense. The problem I’ve always had with heading levels is that, as you say, they form a structural hierarchy, but in terms of the node hierarchy/DOM, all heading levels, paragraphs, etc. are at the same level. If I understand correctly, HTML 5 seeks to work around this by having hierarchical sections. For example, the content of a level 3 heading might be within two nested section elements. The DOM now represents the structural hierarchical of the document.

    Styles in Word are flawed in a similar sense. If you want to drop an entire section down one level, you have to change all of the styles. If I understand correctly, in HTML 5, it’s just a matter of inserting another enclosing section element.

  3. Hi James, I think that is exactly the problem – people keep confusing the document information hierarchy of H1-H6 with the DOM hierarchy of nodes. Your document should make sense as a web page and as a printed page. No?

    We need to take this conversation back to information theory and librarians. Much of HTML was never thought out to reflect the finer points of real documents / life etc. Try marking up a semantic poem, for example. We do our best.

    It is a worry that for some reason the basic common sense of what we all really know underneath about the heading hierarchy of documents in the real world seems to have been fudged into our DOM understanding… we’ve been dealing with documents and information theory for how many centuries now?

    But also regarding the DOM and the spec – why not have all H1 headings (please don’t)??? It’s valid, as far as I know. It is also saying all headings are equal. The only thing it lacks is a meaningful “hierarchy” of information (as opposed to nodes).

    Sorry, I appear to have hijacked the conversation and didn’t mean to. Apologies for that, it’s just one of my sore points over the years.

  4. I should confess I’m not exactly in agreeance about HTML5’s concept of just dropping in more markup to enclose another section element with each having their own H1 etc… it’s a kludge.

    Documents, as I mentioned already, should make sense as documents. I think we, and HTML5 for that matter, are getting a little carried away with our own over-thinking and specification grubbing for loopholes.

    But I guess we’ll all have to agree to disagree on this one. I’ll stop commenting now. Apologies again. 🙂

  5. I think currently multiple H1s are legit if, for example, you have an article in two languages; the title of each would be H1.

    I don’t see it as a terribly likely scenario, however.

  6. meanwhile in the real world screenreader users are so used to most developers fudging the use of structure that we rarely rely on the hierarchy at all. on unfamiliar sites we tend to use any header no matter what the level as a waypoint, and on sites we know well we learn what elements are used for the bits of pages we want to get to. sometimes it’s a header, often it’s something else. taking control of the hierarchy out of the hands of the developer might lead to results us screenreader users can more readily trust but only if coded correctly. Do we trust them?

  7. This has recently been discussed on Accessify Forum. (That link jumps to the part specifically about what <h1> is for.) The site name already being provided by <title> is the reason I stopped wrapping the site name in a heading element.

    In effect <title> is just a heading for the whole document. Kinda like a <h0>. As such, it makes to design the document outline with <title> as the root.

    As for the sectioning model in HTML5, <a href=”
    – versus on #whatwg”>I suspect it’s a bad thing. But I ran out of funding to study that, so I can’t prove it one way or the other.

    As a snapshot of what authors do, my heading usage collection is a good starting point. There’s some interesting approaches to indicate sections without using heading elements near the bottom.

    (There’s a lot of line spacing in this edit box, makes the text look kinda weird. After a quick check, seems to be from setting line-height: 2em on line 927 of style.css. Inputs above it are using line-height: normal. Ability to preview this message would let me see if the code will turn out right…fingers crossed!)

  8. Thanks you for all your comments, I think it’s clear that we still have a ways to go with figuring it out but I’m glad to see that HTML5 is throwing some different light on the issue.

    @steven, rant away isn’t that what blogs are for? And you by no means hijacked the conversation. It funny you and James mention Word and hierarchies as I have seen large documents use multiple H1’s as section headings. I think this has largely been done in order to save an additional level being added to the document and therefore adding to complexity. In the document I’m thinking of the style for title was then used for the document title. Unsure where I stand on the Word example but I do know it is something that was hotly debated by RNB when I worked there.

    As for fudging headings etc why not feed back to the WGAT WG – there’s no better time than now I’d say.

    @adrian, how users use headings is always tricky isn’t it? I suspect there is no right or wrong and a healthy dose of preference based on past experience. There has been some interesting debate on BCAB since I posted about this and it seems that people love them when they are right but like you say, so often they are illogical which results in lack of trust. I guess there are different approaches and feelings about this. WebAim are also planning to do a follow up survey and hopefully they’ll cover the headings debate.

    @ben, thanks for the link. Have to confess it’s been a while since I went to the Accessify Forum…interesting test cases too. Planning a redesign soon and I’ll look at the comment issue as I agree it’s a pain.

    On a final note, I stumbled upon this today on the W3C Tips for webmasters site “use h1 for top-level heading” ( This page is from 2002 admittedly but there none-the-less.

  9. (quote)
    If you’re blind, for example, there are certain key strokes in screen readers that allow you to list the heading structure in a web page …

    FWIW – Using Opera, I habitually “tab” through the headings on a page before reading the content. I did for this article, in fact – but am by no means blind. So, yes, meaningful headings have more than one use.

    I think I’ll stay away from the HTML 5 debate… 🙂

  10. would you say that the use of h1 in each section of an html 5 document is considered “accessibility-supported” under wcag 2? i’d say that until screenreaders can make sense of the nesting level and restructure the various h1s to also reflect the surrounding document’s structure, this is a step back rather than forward.

  11. @David Hucklesby – you’re so right. Headings have a use beyond screen readers, it’s just that screen readers seem to be the poster child of accessibility so we all get a bit pre-occupied by them.

    @patrick h. lauke – I would say they are but you are right in that browsers, screen readers and other user agents need to all be able to interpret them as intended so this method could be an issue today.

  12. I think this article was really interesting. About multiple h1s, I have two scenarios I would like to know what you think should be done:

    1) I have a really really large page (in dimensions, not weight), in reality it should be maybe five-six diffrent pages, but instead it is built as sections on one large sheet. It is possible to navigate to all of these sections from the menu, exactly as if they were there own pages. Should the first heading on each section be a h1?

    2) I have a page where it is inpossible to hierache the headings, they are completely equal. Should I use multiple h1s or should I skip the h1s and only use h2s?

  17. Thank you for this post. I enjoyed reading it. I fall into the category the second part of your article. Namely trying to use h1 tags to the most benefit, and use them so people that need to can easily, clearly and efficiently navigate through the website. Well that’s the idea.

    Currently I am using heading tags as follows:

    h1 class accessibility Content
    h2 post title
    h3-h6 headings in post
    h2 comments

    h1 class accessibility Navigation and information
    h2 sitemap
    h3 headings in sitemap e.g. these are the categories, these
    are the pages
    h4-h6 additional headings where needed
    h2 RSS
    h3 headings in sitemap e.g. these are the categories, these
    are the tags
    h2 Contact
    h2 about me

    h1 accessibility Website name
    h1 class accessibility Copyright information
    h1 class accessibility Search
    h1 class accessibility Breadcrumbs

    The accessibility tag has a display:none in the screen style sheet. So it will only be shown when people need it.

    In other words the styling layout (for visible people) and the accessible layout are separated. I started with this in order to split the content into sections. From what I read in your article it will be implemented in HTML 5. It seems to me a logical way to go for screen readers, but I am not sure. It may be needed to structure it better, but not yet sure which people prefer. For example should the accessibility breadcrumbs be at the top or do people prefer the content at the top. From what I read (some) blind people ideally like the content first.

    I have not experienced any problems with search engines, and also pass automated tests for section 508, WCAG 1.0 or WCAG 2.0 on template pages that are completed. The pages pass W3C validation.

    Somebody was kind enough to point me to your article.. Just wanted to give you feedback on my progress. Thank you for doing a clear writeup. I am open for any suggestions to make the navigation as clear as possible for screen readers in this case.

  18. It’s fair to say the ‘SEO camp’ won’t miss headings all that much anyway – search engines apply very little or no value to H2 or ‘below’ in terms of influencing SERPs.

  19. Hi Gooitzen – thanks for teh detailed response and outline of what you are working on. I’d love to see an actual page if I could so I get a better idea. By all means email me at henny at iheni dot com.

    Dan – It’s always been a bit of a mystery how much search engines give weight to headings in their listing and is no surprise that it’s really the H1 that is focused on.

    SEO per se is not my area so any bits of info like this is great.

  20. Always happy to help. This is based upon strong / ongoing feedback from multiple seo consultants who have experimented with multiple page versions re headings and gauged their effectiveness in influencing search listings. That said, the focus on H1 should only mean that we maybe spend a little less time on optimising keyword text in these ‘lesser’ headings. It still pays to observe a well ordered and well worded headings structure given Google’s push for best practice / well built websites. Lesser headings may not influence search engine results pages (SERPs) as much as H1, but we can assume spiders still read and index headings below H1 much like it does body copy, bold and italic text (the latter SEO measures are actually whole other debates in themselves because web editors often dislike using ‘shouty’ bold text in copy, while the use of italics in web copy is frowned upon in terms of web text being fully accessible for the visually impaired).

  21. Does the problem arise from not being able to state where the end of a section occurs? It starts with a h1, but where does it end? Another h1, a hr, the end of the document?

    A few suggestions: frames, attributes or a meta element.

    I’d argue that there is no real point in defining a header and footer, as suggested in html5, when a normal html layout, clearly seperates the meta information from a document anyway. Then you can use a h1 for each frame. Just glue the frames together. Surely current usability issues could be fixed?

    How about using an attribute for a div, let’s call it importance. So your content div would have an importance of 1, your div id=footer an importance of 8. Think z-index, but with meaning.

    Or a way to define page heirarchy in the head. A simple meta element, , this could use element ids. Or dream up some other use for meta elements.


    strong – sitename
    h2 – nav
    h2- subnav
    h1 – main heading

    With the above, just place less importance for the elements before the h1. Multiple h1s? Use the first or the last, and use the next h1 as a boundary. Don’t want it to print? Hide elements in the style sheet.

    Otherwise, just take some of the ideas of HTML5 and use them as atributes that won’t break existing html (nav, aside or perhaps m-index..). Like with microformats.

    Or maybe allow for a new meta element within the page itself. But that’s probably not backwards compatible.

    I feel the classic frames, solution is the simplest.

  22. You have to think of heading tags according to scope. This is what HTML5 is trying to ultimately solve. Each piece of document has its own scope relative to the document itself.

    Take the element for example. It is supposed to represent an element of the page that can live completely on it’s own. Why shouldn’t it have it’s own heading levels, starting from the top?

    Thinking of a webpage as a single document simply isn’t possible in today’s world. Pages are far to dynamic. Therefore, it should be perfectly fine to use multiple H1’s, however, there should only be a single H1 for its particular scope in the document.

  23. @iheni,

    Should really subscribe to your website.

    In a redesign I changed the website back to one h1. This in order to pass a accessibility test in my country. Using the h1 at the top level still gives me enough room for subheadings, although just barely.

    So a decisive way to separate content for the visual impaired at a top level navigation structure is personally still my favorite option. If screen readers will pick up on the “,` `, “, “, “ and “, this could possibly make life easier. An important aspect will be whether designers can clearly mark sections so that a visually impaired person can easily read what the different parts are. For example how on is to differentiate between a listing of articles on a homepage and a single article.

    You’re still more than welcome to view the source. Using something like Firebug while visiting the site you will always have the latest code. 🙂 If you still want the multiple h1 design I can still mail it to you, or just move all the headings up one level. Hope it helps.

  24. Guys, please check

    If you check the outline of an HTML5 document you’ll notice that the logo’s only logical place is to be at the top level of that outline / DOM tree. If you omit assigning an tag to the logo, you’ll most likely get an “Untitled section” somewhere, anyway. That’s not cool.

    Sorry but it’s logo on the top level for me.

  25. Late, I know…

    I think that is exactly the problem – people keep confusing the document information hierarchy of H1-H6 with the DOM hierarchy of nodes. Your document should make sense as a web page and as a printed page. No?

    My turn to rant.

    I don’t think a web page is a document. A web page *contains* a document, in the context of header, navigation, footer etc. Or more than one document. Just like a printed document is rarely just a document. It’s within a journal, magazine, or whatever.

    I can have a properly structured article – the main content of the page – with proper h1 – h6 headings. But then I’m in a quandary of how to structure the other areas, and land up with h2s before the h1; missing heading levels on some pages where a bit of the header is not logically needed; etc. This aspect of a web page structure often seems to be glossed over in these discussions on heading structure

    So, I’d be happy to have the scopes of article, header, footer, navigation etc, each to have their own heading structure.

    And futhermore I think Cory is right. Modern web pages are dynamic, grabbing bits of content from all over. To eshew this because it doesn’t fit into the “a web page is a single document” model would be to be left behind.

    I s’pose this boils down to how the markup of web pages develop. It would be lovely to predefine it accessibly, and say what web pages should be like. But that’s not and never will be the real webby world. It’s just not the nature of the web. It’s nature is what can be coaxed, wrenched or stuffed into a web page by developers doing things they’re “not supposed to do”, regardless of accessibility. They become the standard that businesses aspire to. This drives developments, for good or bad.

    Perhaps the best we can do is influence this process, and figure how to make structure it accessibly.

    Dynamically constructed pages are here to stay. HTML5 heading structure might just provide the solution for accessibility and access technology to cope with today’s web pages by allowing a web page to be logically structured, albeit recursively, while accommodating at least to some degree modern web page design.

    Until the next development, that is.

  26. I love the new ideas behind H1, h2, and heading sections within articles in general, it’s going to make markup wonderfully more easy to read through and understand, instead of relying on individual developers ideas (for example, the new FOOTER tag in a section will often be labeled DIV CLASS=”POSTMETA”, etc.) but it’s also going to be a nightmare for WordPress users who have h3, h4, and so on embedded in their posts and pages. If we want to move toward using H1 as the first heading of a section, think about how many posts will need to be scoured, or find/replaced in MySQL for those of us fortunate enough to know how to do it, so that we can bump all of those h3s up to h2s, h4s to h3s, and so on.

    Daunting…but great article. Not sold yet, but we’ll see how the consensus plays out.

  27. In regards to a webpage not being a document, because it’s like a magazine, journal, or book.

    I completely disagree. You break up your webpages, they stand alone as documents. You reference them separately.

    The header, footer, and nav is not the cover of the magazine. They are the little bits of text on the top and bottom of each page to denote the magazine title, the section title, the page number, et al.

    These elements are not relevant while reading the magazine article they surround. Similarly, they do not have weight in regards to the primary content of the webpage. They are merely context, and ways to get to other pages. In a magazine, you can always turn the page, flip back to the table of contents, or close it to look a the cover.

    There’s always another level to present as a document. An article. All articles in the magazine. The entire magazine issue (with editor’s note et al). All magazine issues. The magazine as a collection. The magazine as an organization.

    However, in all these levels, it is very clear what is primary and what is secondary or contextual.

    If you have a whole book on one page, the book title is h1, table of contents is h2, sections are h2, chapters are h3, index is h2. It makes even more sense if you think about a textbook instead of a novel. Logical groupings multiple hierarchical levels to break up info.

    If a book is split by parts (sections, chapters, et al), then you can present each part as a separate page, with references to the other parts and the book as a whole.

    The christian bible is another good example, with the chapter and verse structure. Specific verses are often referenced specifically, so it is reasonable that they may exist on their own webpages to facilitate (h1 is chapter:verse). However, of course they may be viewable in context with the chapter as a whole on a single webpage (h1 is chapter). Further, the entire book may be presented as a whole (please don’t) to facilitate download or offline reading.

    To use a popular web example: a blog. A blog may be a webpage (h1 is blog title), to show articles sorted by recent first (article titles are h2). Obviously each blog article is it’s own webpage (h1 is article title), with list of comments. If comments are to be referenced alone (as with a forum, a reply is merely a post with a parent), then a comment may be granted an h2 and a link, given that it may be an h1 on its own webpage.

  28. When someone writes an article he/she maintains the plan of a user in his/her mind that how a user can know it. So that’s why this article is amazing. Thanks!

  29. It is truly a nice and helpful piece of information.
    I am satisfied that you just shared this useful info with us.
