Free Meta Tag Checker: title, description, H1 and schema

It requests your page's live initial HTML and reports the title tag, meta description, H1 headings, the HTTP status code, and any JSON-LD structured-data schema types it detects in that response.

A meta description is an HTML tag summarizing a page's content. Search engines may show it as the snippet under your title in results, so a clear, relevant one can improve click-through even though it is not a direct ranking factor.

There is no universal character limit because result titles are constrained by rendered width and may be rewritten. Use the measured count as a review cue, keep the identifying words early, and judge clarity in context.

Add a single, descriptive H1 heading that states the page's main topic. The checker lists detected H1s, so if none appear or several compete, you can consolidate to one clear heading.

The title tag is a strong on-page relevance signal and the clickable headline in results; the meta description shapes the snippet. Together they influence whether searchers understand and click your listing.

JSON-LD is a script format for embedding schema.org structured data in a page. It helps search engines understand entities like articles, products, or FAQs, and can enable rich results. The tool reports which schema types it detects.

It reads the initial HTML response only. If your title, description, or JSON-LD is injected after browser JavaScript runs, it may not appear here even though a full browser render would show it.

The title tag lives in the HTML head and appears in the browser tab and search results; the H1 is a visible on-page heading. They often align but serve different placements and audiences.

One clear main heading is a useful editorial convention, but HTML permits multiple H1 elements. The checker reports what the initial HTML contains; whether the hierarchy is clear still requires review.

A 200 OK confirms the page is live and its metadata applies. Redirect or error statuses like 301 or 404 mean crawlers may not see the content you expect, so investigate those first.
