A free Chrome extension that shows every redirect between the URL you typed and the page you landed on, with status codes, timing and protocol for each hop, plus the final page's indexing, caching and security headers. Nothing leaves your browser.
Open the popup on any page and get twelve on-page checks marked pass, warning or fail: title and description length, canonical, meta robots, the robots.txt rule for that URL, H1, image alt, language, viewport, schema, hreflang and word count.
Seven tabs go deeper: a headings outline, a link checker that HEAD-requests every URL to find broken ones, image file sizes, every JSON-LD block, the Open Graph card, and keyword density. It all exports to CSV or JSON.
Free, no account, no tracking.
