The maximum number of H1 tags you should use on a page is one. Having more than one H1 tag can actually make it more difficult for search engines to accurately categorize your webpage, as they may believe your webpage doesn’t have a primary focus. For example, when two or more H1s are used on the same page, search engines may think that the topic of the dossier shifts midway through which could hurt the accuracy of their rankings. Additionally, having too many H1 tags can confuse users who are trying to quickly assess what the main message of your website – and its page title – is about. In summary, one H1 tag is sufficient to designate the key information of your page and make it easier for search engines and users alike to understand it.
