RankMiso

A free, open-source SEO browser extension.

RankMiso reads the page open in your browser and reports the SEO details it can actually measure. Included: - Title, description, canonical, robots, headings, links, images, and JSON-LD syntax - A local checklist score that leaves out checks it could not run - Approximate social cards - A resource count from this browser's timeline for the current page load - Optional checks you start yourself, for one site: response headers, robots.txt, whether this URL is in the first listed sitemap, redirect hops, hreflang return links, and public links 20 at a time Not included: - Search rankings, traffic, backlinks, or index coverage - PageSpeed Insights or Chrome UX Report field data - Largest Contentful Paint, Cumulative Layout Shift, and Interaction to Next Paint. Those cards stay Unavailable in this version - Official rich-result eligibility. The JSON-LD row is a local field list - A crawl of your browsing history Optional checks ask for permission for that site only. They are off until you press Check this site. Analysis stays in the browser. No account, no telemetry, no ads.
