Read-only SEO basics and tracker detection for the page you are on. On-device. Nothing is sent. Site Check is a quick, read-only audit of the page you have open. Click the icon to get one clear report: • Overview: a shareable summary of the page's SEO health, the tags it loads, and its tech stack. • SEO: title and meta description length, canonical, robots meta, language, viewport, heading outline, Open Graph and Twitter cards, structured data types, images missing alt text, links, hreflang, word count, and a plain-language indexability summary. • Trackers: common analytics and ad tags, plus session-replay scripts. Shows the IDs it finds and how each tag was detected. • Tech: a short, confident list of the CMS, ecommerce platform, framework, CDN, hosting and payment tools in use. Copy a single value, or copy the whole report as Markdown or plain text. Private by design: Site Check never changes or blocks the page and sends nothing anywhere. There is no account, no analytics and no remote code. Notes about a tab live in your browser's session storage and are removed when you close the tab. Available in English and Dutch, with light and dark themes. Limits: server-side tagging and first-party proxies can hide tags, so an empty tracker list does not prove that a site sets no cookies. Made by Cookie Free Analytics (cookiefreeanalytics.com), cookieless web analytics.
