Fetch a public page and get a fast health snapshot: HTTP status, title and meta description with length checks, canonical, robots, viewport, charset, H1 count, page size, and more.
Pro tip: Aim for a single H1 and a 30-65 character title; the table flags both with a warning tone when off.
Give the tool a page address and our Cloudflare edge retrieves the HTML, follows any redirects, and pulls out the handful of signals that decide whether a page is set up sensibly for search and sharing. Rather than scrolling through view-source, you get a compact overview: did the page return 200, is it on HTTPS, is it indexable, how heavy is the HTML, and are the core head tags present and a reasonable length.
It is the check to run first on any page before reaching for deeper, more specialised audits, because it surfaces the most common mistakes in one pass.
Treat each missing, default, or out-of-range value as a to-do. A missing title or description is a quick content fix, and a flagged length is a nudge to tighten or expand the text so it displays cleanly in results. A canonical that points at a different page than you intended can quietly suppress the page you actually want indexed, and a meta robots tag containing noindex will keep it out of search entirely. A missing viewport tag suggests the page may not adapt to phones, more than one H1 muddies the page structure, and an unusually large HTML payload is worth trimming. The snapshot tells you where to look; the actual edits happen in your CMS or template.
Everything reported is read from the HTML returned at request time, so signals injected later by JavaScript may not be captured. The length thresholds are sensible rules of thumb, not hard rules, and the tool reports what the tags contain rather than judging whether the wording is compelling for your audience, which remains your call. The page-size figure is the weight of the HTML document itself, not the full page including images, scripts, and fonts. Pages that block automated fetches with our identified tool user agent, or that require a login, may return an error or partial content instead of the real page. Only publicly reachable URLs can be checked.
Input: https://example.com/blog/post
Output: Status: 200 · HTTPS: Yes · Indexable: Yes · Page size: 38 KB • Title: "How We Built It" (15 chars, flagged short) · Meta description: (missing) · Canonical: self · Viewport: Present · H1 tags: 1
The absent description and the short title are two easy wins to add.
Input: https://example.com/landing
Output: Status: 200 · HTTPS: Yes · Indexable: No • Meta robots: noindex, follow · Title: "Spring Sale" (11 chars) · Viewport: Present · H1 tags: 2
The noindex tag will keep this page out of search; the two H1s are a smaller cleanup.
No. It is a fast snapshot of core on-page signals. For a scored review use the SEO score checker, and for one element in depth use the dedicated tools for links, Open Graph, or page size.
They are sensible ranges, roughly 30 to 65 characters for the title and 70 to 165 for the description, that tend to display without truncation. A flag is a nudge to review the length, not a hard error.
The page is nominating that other address as its primary version. If that is unintended, it can stop the page you care about from being indexed, so it is worth correcting.
No. It measures the weight of the returned HTML document only. For a fuller picture of total page weight, use the page size checker.
No. The edge fetches the page anonymously, so anything requiring authentication will not be retrieved.
It reports the title that exists and whether its length is reasonable. Deciding if the wording is compelling for your audience is left to you.
