Multiple H1s

Multiple H1 Headers on Single Page

In this guide we describe what this element is (H1 header), what the check is and how it works as well as providing some context as to why this SEO check is performed. This check is performed exclusively on canonical pages (pages with a self-referential canonical tag).

 

What is a H1 Header?

H1 headers are the primary header on any page and they can yield significant benefits to the SEO of a page when optimised for target keywords. A H1 header is defined at the tag and text contained within the tag:

<h1>example header text goes here</h1>

The H1 header is designed to head all the content on a page and is usually the most prominent text on a page. Typically found at the top of a page and in larger font than the rest of the text.

 

What is a Canonical Page?

A canonical page is a webpage that has a self-referential canonical tag present on it. A canonical tag advises Google as to the preferred / original version of content. If a page / piece of content is accessible from multiple URLs or is missing across multiple pages, a canonical tag helps to define the ‘canonical’ version.

A canonical tag contains a URL and if that URL matches the URL of the page being accessed, it is defined as a canonical page. Canonical pages are typically the ‘SEO’ pages of a site as they are most likely to appear in the search results. The canonical tag of our homepage looks like this in HTML:

<link rel="canonical" href="https://raptor-dmt.com/">

 

What are Multiple H1s?

‘Multiple H1 headers’ is where a single page has more than one H1 header present on it. If the page is using / built in HTML5 then this won’t be a technical error. However, this is often the result of poor implementation of headers and can dilute the relevance a page has to its target keywords.

 

What Do We Check & How?

Our SEO tool extracts the H1 header text from every page and then runs a script to identify pages containing more than one set of tags. It does not matter what text is used within the H1 header tag, just that a single page has more than one set of tags present on it.

As mentioned previously, these checks are performed exclusively on canonical pages, so if a non-canonical page has multiple H1 header tags present, it will not be included within this check. You can see all pages (regardless of their canonicalization) that have more than one set of H1 header tags under the ‘headers’ section in the SEO errors report.

 

What Should You Do With This Data?

Using our software to identify multiple H1 headers across your site allows you to isolate problem pages and deploy a solution:

  • Remove extra headers
  • Change the header tag to a different number (h2, h3, h4, etc)
  • Provide the list of pages with multiple H1 headers to a client
  • Count the SEO errors on a site
