SEOmator: SEO Extension

Inspect any page for SEO: meta tags, indexability, headings, links, images, structured data and hreflang.

SEOmator shows you what search engines see on any page, the moment you click the icon. KNOW IF A PAGE CAN RANK One verdict tells you whether the page is indexable, and why: the HTTP status, robots.txt rules, noindex in the page or its headers, and where the canonical tag points. SEOmator re-checks the page's headers without your cookies, so a logged-in session doesn't hide what a crawler gets. FIX THE RIGHT THINGS FIRST The Issues list ranks what matters: missing or overlong titles and descriptions, missing H1s, skipped heading levels, images without alt text, links without anchor text, conflicting canonicals and more. Click an issue to jump straight to it. EVERYTHING ON THE PAGE, ORGANIZED • Search appearance: title and description length in characters and pixels, with a preview of the Google result. • Headings: the full outline with hierarchy warnings. • Links: internal, external and other links with nofollow, sponsored and UGC markers, filters, search and CSV export. • Images: alt text, rendered and natural sizes, oversized images and CSV export. • Structured data: JSON-LD and microdata as a readable tree, invalid blocks flagged, one click to Google's Rich Results Test. • Hreflang: alternates checked for their status and return link, the first 50 at once or all of them on request. • Social: Open Graph and X card previews with the tags behind them. • AI readiness: which AI crawlers your robots.txt allows, and whether the site has an llms.txt file. TOOLS WHEN YOU NEED THEM Highlight nofollow links on the page, run site: searches, open the page in PageSpeed Insights, the Rich Results Test and other popular SEO tools, or start a full SEOmator site audit with the URL already filled in. PRIVATE BY DESIGN • No site-access warning at install: SEOmator reads a page only when you click its icon. • No analytics, no tracking, no account. • Page data stays in your browser. The only requests it makes are the checks you'd expect: the page's own headers, its robots.txt and llms.txt, hreflang alternates, image previews from the page itself, and the tools you choose to open. MADE FOR DAILY USE Light and dark themes that follow your system, full keyboard support, and a layout that adapts to browser zoom. Open it with Alt+Shift+S, or change the shortcut at chrome://extensions/shortcuts. From SEOmator, the SEO audit platform: https://seomator.com
