4. Google Search Console - Real Search Data
Google Search Console isn't a generic "audit tool" - it's Google's free tool that shows how Google sees your site. You can see which pages are indexed (in Google's database and eligible to appear in search), how often you show up in search results, your Core Web Vitals (speed and stability metrics), and any manual actions (problems Google has applied to your site). You must verify that you own the site. Best for: anyone who already has a site live and wants to pair a technical audit with real search data. Use it alongside a free SEO checker for a fuller picture.
5. PageSpeed Insights - Speed and Core Web Vitals
PageSpeed Insights is Google's free tool that tells you how fast your page loads and how it performs on a few key speed and stability metrics (Core Web Vitals). No signup. Best for: a quick speed-only check. For a single report that combines speed with SEO and accessibility in plain language, AuditCrow is a good complement.
