Site Audit
Enter a domain to crawl its sitemap.xml and audit every page found. Get SEO scores across your entire website in one go.
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:
- Sitemap.xml — checks common paths: /sitemap.xml, /sitemap_index.xml, /feeds/sitemap.xml, /wp-sitemap.xml
- Robots.txt — if no sitemap found, checks robots.txt for a Sitemap directive
- 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, structured data, and Lorem Ipsum placeholder text. Click Details on any result for the full breakdown.
Common Issues Found in Site Audits

| Missing meta descriptions | Google generates its own snippet, often poorly |
| Duplicate title tags | Search engines confused about which page to rank |
| Missing H1 tags | No clear main heading for search engines |
| No structured data | Missing rich results in Google |
| Missing alt text | Poor accessibility, missed image search traffic |
| Lorem Ipsum placeholder text | Signals unfinished content, damages credibility and rankings |
