Quick on-page SEO check of the page you're viewing: titles, meta, headings, structured data, images, and issues. Crawlpit Monster - Quick On-page Check See the on-page SEO of the page you're on, in one click. It reads the live, rendered page (so it works on JavaScript-rendered and logged-in pages) and shows a clear, actionable report - no account, no server, and nothing to set up. WHAT IT CHECKS - 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 (article, product, etc.) - Images, plus a list of every image missing an alt attribute - Internal and external link counts - Canonical URL, meta robots, and robots.txt - combined into an indexable / not-indexable verdict with the reason - A Google-style search result (SERP) preview of your title and description - A prioritized list of on-page issues to fix PRIVATE BY DESIGN Everything runs on your device. The extension only looks at the current tab when you click the icon (activeTab), it never runs in the background, and it does not collect, store, transmit, or sell any data. The only network request it makes is reading the site's own robots.txt to determine indexability. GOOD TO KNOW Some checks need a full site crawl and are shown as "not checked here": HTTP status code, TTFB, redirect chains, duplicate titles/descriptions across pages, inlinks, orphan status, and crawl depth. For those, run a full crawl in the Crawlpit Monster desktop app. 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.
