Run the full audit when you want the complete 100+ check report with a scored breakdown and prioritized fix list.
Want a scored report for a single page instead of a single check? Our sister tool SEO Analysis Checker runs 40+ weighted checks against one URL in about 10 seconds — also free, also no signup. It stops at one page; the full audit here crawls up to 1,000.
