How to Run a Free SEO Audit on Any Website

A free SEO audit scans a single URL for the issues that block rankings — meta tags, Core Web Vitals, schema markup, content quality, internal links, image alt text, canonical tags, HTTPS security and robots directives — and returns a prioritized fix list. AuditMe runs 159 checks across 16 categories and delivers the report in about 60 seconds: no signup, no credit card, 1 free audit per day.

AuditMe's 86 free SEO tools cover everything around the audit: SEO score calculator (0–100 from 12 weighted factors), meta tag analyzer, schema validator, rank tracker, AI content detector and competitor research — all free, no signup.
