What does the Quick On-page Check extension check?

In one click, the extension reads the current page and reports every on-page SEO signal, with a prioritized list of issues to fix.

  • Title and meta description, with character-length indicators
  • Heading outline (H1, H2, H3) and H1 count
  • Open Graph tags
  • JSON-LD structured data, and the page type it implies
  • Images, plus every image missing an alt attribute
  • Internal and external link counts
  • An indexable verdict from canonical, meta robots, and robots.txt, with the reason
  • A Google-style SERP preview, and a prioritized list of on-page issues

Works on JavaScript & logged-in pages

Because it reads the live, rendered page rather than raw HTML, the extension audits pages that JavaScript builds, staging environments, and pages behind a login, which most on-page SEO extensions miss entirely.

Private by design

Everything runs on your device. It only reads the current tab when you click the icon, never runs in the background, and does not collect, store, transmit, or sell any data. Its one network request reads the site's robots.txt. See the privacy policy.

How is it different from the desktop app?

The extension checks the single page you are on. Checks that need a full site crawl are marked "not checked here" and run in the Crawlpit Monster desktop app for Mac. Those page-versus-site checks are:

  • HTTP status code
  • Response time (TTFB)
  • Redirect chains
  • Duplicate titles & descriptions
  • Inlinks
  • Orphan pages
  • Crawl depth

For a full technical SEO audit across up to 50,000 pages, get the free Crawlpit Monster desktop app for Mac. The extension is the fast, single-page companion.

Who it's for

SEOs, developers, content editors, and anyone who wants a fast, honest on-page audit of the exact page in front of them, including staging sites and pages behind a login. It is free, it needs no account, and it adds a one-click on-page SEO check to any tab.

Chrome extension FAQs

Is the extension free?
Yes. Quick On-page Check is free with no account and nothing to set up. Click the icon and it reports the on-page SEO of the current page.
Does it work on JavaScript and logged-in pages?
Yes. It reads the live, rendered page rather than raw HTML, so it works on JavaScript-rendered pages, staging sites, and pages behind a login that most SEO extensions cannot see.
Does the extension collect my data?
No. Everything runs on your device. It only reads the current tab when you click the icon, never runs in the background, and does not collect, store, transmit, or sell any data. Its only network request reads the site's robots.txt to determine indexability. Full details are in the privacy policy.
How is it different from the Crawlpit Monster desktop app?
The extension checks the single page you are on. Checks that need a full site crawl, like HTTP status, TTFB, redirect chains, duplicate titles, inlinks, and orphan pages, are done in the desktop app for Mac, which crawls up to 50,000 pages.
