SEO meta checker
The page is fetched once through our reader (10 requests/min) and analysed locally: nothing is stored, and you can also paste HTML directly to audit without any network at all. Checks follow what Google actually documents — lengths are guidance, missing canonicals and stray noindex are the real killers.
- Runs from your browser, not our server
- No sign-up
- No watermark
Loading the tool…
How it works
- Enter the page URL (or paste its HTML for the offline mode).
- Read the pass/warn/fail list — each row shows the actual value found.
- Fix what is red, re-run, and compare the redirect chain if something looks off.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
Why can’t the browser fetch the page by itself?
Cross-origin security (CORS): a web page cannot read another site’s HTML. Our small reader fetches the page server-side — public URLs only, 10 requests per minute — and hands the HTML back to your browser, where all the analysis happens.
What exactly is checked?
HTTP status and redirect chain, X-Robots-Tag, title and meta description presence and length, meta robots (noindex/nofollow), canonical, hreflang set, Open Graph basics, H1 count, lang attribute, viewport, charset and the share of images without alt text.
Are the length limits official?
No — Google truncates by pixels, not characters. The 10–60 character title and 50–160 description ranges are practical guidance for staying inside the usual truncation, flagged as warnings, never failures.
Is anything stored?
Nothing. The reader returns the HTML and forgets it; the audit runs in your browser and the result never leaves it.
