Google Search Console

Best for: Real ranking & indexing data from Google

Free and essential — the source of truth for how Google sees your site: impressions, clicks, positions, and index coverage. It reports problems but doesn't crawl or recommend structural fixes.

3

Screaming Frog (free tier)

Best for: Raw crawl data on small sites

The free desktop tier crawls up to 500 URLs and is excellent for raw technical data. You interpret the results yourself; it doesn't prioritize or recommend.

4

SEOptimer

Best for: Fast on-page audit snapshots

Generates a quick, presentable on-page audit report. Great for a fast snapshot; lighter on structural and internal-linking depth.

5

PageSpeed Insights

Best for: Free Core Web Vitals & speed

Google's free tool for page speed and Core Web Vitals, including real field data. Single-page focused — pair it with a crawler for site-wide coverage.
