SEO Launch Auditor - Technical SEO Audit

Technical SEO audit for pages and small sites. Check on-page SEO, find launch blockers, and recheck changed pages.

SEO Launch Auditor is a technical SEO audit and site audit extension for checking pages and small websites before launch. Run an on-page SEO audit on the page you have open, or a broader website SEO audit across a small site. Catch launch blockers before publishing. SEO Launch Auditor checks indexing directives, canonical tags, titles and descriptions, headings, internal links, images, JSON-LD structured data, basic accessibility, mixed content, and differences between source HTML and the rendered DOM. Findings include evidence, confidence, why the issue matters, and a practical fix. Checks that cannot be confirmed are shown separately as “Could not verify.” THREE WAYS TO CHECK YOUR SITE • Current Page — audit the page you are viewing directly in Chrome. This mode runs entirely in your browser and sends nothing to the public audit service. • Full Site Crawl — explicitly start a bounded site audit of up to 100 public pages. SEO Launch Auditor’s public audit service discovers and fetches public pages on the same site. • Changed Pages — after a fix or deploy, recheck only the URLs you select, up to 20 at a time, instead of crawling the whole site again. Successful rechecks update your saved site baseline while unrelated pages are preserved. LAUNCH READINESS, NOT A RANKING SCORE The Launch Readiness Score shows category breakdowns, deductions, caps, and verification coverage. It is designed to help you decide what to fix before publishing. It is not a Google ranking score and does not guarantee rankings, indexing, or traffic. SAVE, COMPARE, AND EXPORT • Save reports locally in your browser. • Compare before and after a fix or deployment. • See new, changed, resolved, and unchanged findings for Changed Pages. • Copy a structured summary for a coding assistant or ticket. • Export JSON, CSV, or self-contained HTML, or print the report. • Back up or clear all extension-owned local data from History. PRIVACY BY DESIGN • No account, email, or login. • No telemetry, analytics, ads, or affiliate links. • No remote code. • No automatic scanning of other tabs. • Current Page audits stay in your browser. • Full Site Crawl and Changed Pages run only after you explicitly start them. SEO Launch Auditor is a focused SEO checker and SEO auditor for launch hygiene, not a replacement for Google Search Console, a dedicated enterprise crawler, Lighthouse/PageSpeed, a full accessibility audit, or professional SEO judgment. The extension interface and generated reports are currently English-only. Desktop Chrome only.
