What Makes SEOAudits Different?
SEOAudits's SEO tools are different because they include GEO scoring that helps your content get discovered by AI search engines like ChatGPT, Perplexity, and Google SGE.
Our scoring engine analyzes 15+ critical SEO factors across four categories: Technical SEO (30%), Content & Structure (30%), UX & Accessibility (20%), and Performance (20%). Each issue is assigned a severity level (Critical, Warning, Info) and a point impact, so you know exactly what to fix first.
But we do not stop at traditional SEO. SEOAudits is the first audit platform to include GEO (Generative Engine Optimization) scoring — measuring how well your content is structured for AI search engines like ChatGPT, Perplexity, and Google SGE.
Key Terms

- A set of three metrics (LCP, CLS, FID) that measure user experience in terms of loading speed, visual stability, and interactivity. Google uses them as ranking factors.
- Schema Markup
- Structured data added to HTML using JSON-LD, Microdata, or RDFa. It helps search engines understand the content and context of a page, enabling rich snippets.
- Crawl Budget
- The number of pages a search engine bot will crawl on your site within a given timeframe. Optimizing it ensures your most important pages are discovered and indexed.

Frequently Asked Questions
Are these SEO tools really free?
Yes. The free plan includes 1 audit per month covering up to 25 pages. This is enough for most small websites and blogs. Upgrade to Pro or Agency for larger sites.
How accurate is the Core Web Vitals test?
SEOAudits uses Google Lighthouse for performance measurements, which is the same engine Google uses for Core Web Vitals. Our results are highly accurate and correlate strongly with field data from the Chrome User Experience Report.
What is GEO optimization?
GEO (Generative Engine Optimization) is the practice of structuring your content so AI search engines can easily understand, extract, and cite it. SEOAudits checks for FAQ schema, structured lists, fact density, question-based headings, and more.
