SEO Fundamentals

What is H1 tag?

The primary heading on a webpage, marked with the `<h1>` HTML tag. Google reads H1 as the strongest single signal of what the page is about, so every page should have exactly one.

Common mistake: having two H1 tags on a page (often from a theme bug or an announcement bar). This confuses Google about the page topic and can suppress ranking by 15–30%. Modern best practice is one H1 per page, containing the primary keyword.
