H1 Checker

One. A single H1 that states the page’s main topic gives search engines and AI systems a clear primary heading. Multiple H1s compete as “main” titles and weaken that signal; a missing H1 leaves crawlers to guess the topic from the title tag or body copy.

The title tag lives in the HTML head and is what usually appears as the clickable headline in search results. The H1 is the visible page heading on the page itself. They should describe the same topic and often share key phrases, but they are not interchangeable — one shapes the SERP snippet, the other anchors on-page structure and readability.

H1s are not a direct ranking “score,” but they are a strong relevance cue. A clear, topic-aligned H1 helps Google and Bing understand what the page is about and how it relates to a query. Missing, duplicate, or misleading H1s make that harder and can leave other on-page signals doing more of the work.

Large language models and AI answer engines lean on heading structure to outline a page before summarizing or citing it. A clear H1 names the main subject; well-labeled H2s break the argument into sections those systems can lift accurately. Vague or flat heading trees make pages easier to misread or skip in AI-generated answers.

Yes — include the primary topic people search for, in natural language, not as a stuffed list. Weak H1s are vague (“Welcome,” “Services,” “Home”) or so generic they could fit any page. Pair a specific H1 with a logical H1→H2 hierarchy so each section heading advances the topic instead of repeating the same bland label.
