My 2026 free toolkit is: Google Search Console for indexing and crawl data, Google Analytics 4 for traffic insights, Ahrefs Webmaster Tools for backlink audits, Screaming Frog SEO Spider (free tier) for technical scans, plus PageSpeed Insights.

Together they cover crawl budget, SERP visibility, link equity, indexing, and on-page diagnostics.
