H1 Tag
The main heading of a page, telling users and search engines what the page is about.
The H1 tag is the main heading of a web page. It's the largest, most prominent heading and should clearly describe what the page is about. In HTML, it looks like: <h1>Your Main Heading</h1>.
Every page should have exactly one H1 tag. It's the first thing users read and one of the first things search engines look at to understand a page's topic. Your H1 should include your primary keyword naturally — not stuffed in awkwardly.
H1 is different from the title tag. The title tag appears in search results and browser tabs. The H1 appears on the actual page. They can be similar but don't need to be identical. The title tag has character limits for display purposes, while the H1 can be longer.
After the H1, use H2 tags for main sections, H3 for subsections within H2s, and so on. This creates a clear content hierarchy that both users and search engines can follow. Don't skip heading levels (jumping from H1 to H4) — it's bad for accessibility and SEO.
Why It Matters for SEO
The H1 tag is a strong on-page SEO signal. It tells search engines and users what your page is about. Missing, duplicate, or poorly written H1 tags are one of the most common on-page SEO issues, and one of the easiest to fix.
