SEOTyde

Instant on-page SEO audit: score, Google/social preview, broken links, page speed, competitor compare. 100% local, no AI.

SEOTyde gives you an instant, complete on-page SEO audit for any website — right in your browser, with zero setup and zero data collection. WHAT IT CHECKS ✓ Title tag & meta description (length + presence) ✓ H1/H2 heading structure, with a full outline tree ✓ Image alt text coverage ✓ Canonical tags & meta robots (catches accidental "noindex") ✓ Open Graph & Twitter Card tags ✓ Mobile viewport tag ✓ Structured data / JSON-LD ✓ Content length SEE HOW YOUR PAGE ACTUALLY LOOKS Most SEO extensions just tell you a character count. SEOTyde shows you a live mockup of your Google search result snippet and your Facebook/LinkedIn social card — so you know exactly what visitors will see before you publish. CHECK YOUR SPEED & LINKS Get load time, page weight, request count, and DOM size straight from the browser's own Performance API — no external tools needed. Then scan your internal links for anything broken. COMPARE AGAINST COMPETITORS Paste in any competitor URL and SEOTyde fetches it, runs the same scoring engine, and shows you a side-by-side comparison table — title length, word count, structured data, and more. TRACK YOUR PROGRESS SEOTyde remembers your score for each page you visit and shows you whether it's trending up or down over time — all stored locally on your device. READABILITY & KEYWORDS Get a Flesch Reading Ease score for your content, check keyword density for any target term, and highlight every occurrence directly on the page with one click. EXPORT FOR CLIENTS Download a complete Markdown report of any audit — perfect for freelancers and agencies delivering SEO reports. PRIVACY FIRST SEOTyde runs 100% locally in your browser.

Perfect for bloggers, developers, freelance SEO consultants, small business owners, and anyone who wants to understand and improve their website's on-page SEO — instantly.
