What Is a Site Audit?

A site audit is a comprehensive analysis of every page on your website. Instead of checking one URL at a time, the site audit discovers all your pages and runs 30+ on-page SEO checks on each one. The result is a complete picture of your website's SEO health with average scores, worst-performing pages, and common issues.

How RankNibbler Discovers Your Pages

RankNibbler uses a three-step discovery process:

  1. Sitemap.xml — checks common paths: /sitemap.xml, /sitemap_index.xml, /feeds/sitemap.xml, /wp-sitemap.xml
  2. Robots.txt — if no sitemap found, checks robots.txt for a Sitemap directive
  3. Homepage crawl — if no sitemap exists, crawls the homepage for internal links as fallback

What Gets Checked on Each Page

Every page is scored out of 100: title tag, meta description, H1/H2 headings, canonical URL, robots directives, word count, text-to-HTML ratio, image alt text, HTTPS, viewport, lang, favicon, Open Graph, and structured data. Click Details on any result for the full breakdown.
