Free SEO tools that connect directly to your Google Search Console data - no third-party database required. The GSC-connected tools (GSC Dashboard, Opportunity Finder, CTR Finder, Cannibalization Checker) read your live performance data via read-only OAuth, surfacing insights that generic keyword tools miss because they're based on your actual traffic. Standalone tools (PageSpeed Checker, Schema Tester, Redirect Checker, Hreflang Generator, Robots.txt Tester) work without any login. Together they cover the full technical SEO workflow: diagnosing crawlability issues, improving search snippet CTR, identifying quick-win ranking opportunities, fixing structured data, and auditing redirect chains - all without paying for an enterprise SEO platform.

When to use SEO & Analytics

1Monthly traffic reviews: connect your GSC account and run the Opportunity Finder to surface queries stuck in positions 4–20 with the highest upside.
2Before publishing or updating a page: use the Schema Tester to validate your JSON-LD and the Meta Preview to check how the title and description will appear in Google.
3After a site migration or domain change: run the Redirect Checker on all old URLs to confirm 301 chains are clean and no hops are missing.
4International SEO projects: use the Hreflang Generator to create the full set of alternate tags for every language/region variant and validate the configuration.
5After a traffic drop: check the Anomaly Detector, Redirect Checker, and Robots.txt Tester to quickly rule out technical causes before investigating content.

Frequently Asked Questions

Do I need a Google Search Console account to use these tools?+

Only the GSC-connected tools (GSC Dashboard, Opportunity Finder, CTR Finder, Cannibalization Checker, Keyword Tracker, Anomaly Detector) require a Google Search Console account and read-only OAuth. All other tools in this category - PageSpeed Checker, Schema Tester, Redirect Checker, Robots.txt Tester, Hreflang Generator, Meta Preview, UTM Builder - work instantly with no login.

How is this different from Ahrefs, Semrush, or Moz?+

Those tools use their own crawl databases to estimate traffic and rankings. Searchlight reads your actual Search Console data - clicks, impressions, CTR, and position for every query you rank for. There is no sampling or estimation. The data is your real performance as Google sees it.

What is keyword cannibalization and how do I detect it?+

Keyword cannibalization is when two or more pages on your site rank for the same query, splitting ranking signals between them. Both pages rank lower than one consolidated page would. The Cannibalization Checker clusters your GSC queries by URL overlap and flags the affected keywords so you can consolidate, redirect, or canonicalise.

How do I improve my page's click-through rate from Google?+

CTR is primarily driven by your title tag and meta description. Use the CTR Finder (connected to your GSC data) to identify pages where CTR is below the average for their ranking position. Then use the Meta Preview tool to rewrite and visually check the snippet before publishing the changes.
