H1 Tag SEO FAQ
Can I have more than one H1 tag on a page?
While HTML5 technically allows multiple H1s (one per section), SEO best practice is to have only one primary H1 that defines the page topic.
Should the H1 be the same as the Page Title?
They should be similar and contain the same keyword, but the H1 can be longer and more descriptive than the meta title.
Does the H1 tag affect rankings?
Yes. It is one of the strongest on-page ranking factors as it tells search engines what the most important content on the page is.
What is the ideal length for an H1 tag?
There is no strict character limit, but it should be concise enough to be readable—usually between 20 and 70 characters.
Where should the H1 tag be placed?
The H1 should ideally be placed near the top of the page, above the main content, acting as the title for the article or page.
Is an H1 tag necessary for accessibility?
Absolutely. Screen reader users rely on H1 tags to understand the page's purpose and to navigate content effectively.
