What is GEO (Generative Engine Optimization)?

GEO stands for Generative Engine Optimization. It is the practice of optimizing your website to appear in AI-generated answers from ChatGPT, Perplexity, Google AI Overviews, and Claude. Foglift is the first tool to combine SEO and GEO analysis in one scan.

What does Foglift analyze?

Foglift scans websites across 5 categories: SEO (meta tags, headings, Open Graph), GEO (AI-crawler access, structured data, citation-readiness), Performance (Core Web Vitals, load time), Security (HTTP headers), and Accessibility (WCAG compliance, contrast, alt text).

How is Foglift different from Ahrefs or Semrush?

Ahrefs and Semrush focus only on traditional SEO. Foglift is the first tool to combine SEO + GEO (AI search optimization) analysis, checking if your site is ready for AI-generated answers. It starts free and costs 10x less than alternatives.

Does Foglift have an API?

Yes. Foglift offers a free public REST API at foglift.io/api/v1/scan that returns JSON results. Developers can use it from the terminal, CI/CD pipelines, or AI coding assistants like Claude Code and Cursor.

Why do SEO tools have low security scores?

Many SEO tools are missing security headers like Content-Security-Policy (CSP), HSTS, and Referrer-Policy. These headers protect against XSS attacks and data leaks. While they don't directly affect search rankings, they signal trustworthiness to both browsers and users.

We used Foglift's free website scanner to analyze 28 of the most popular SEO tools, content platforms, and marketing agencies. Each site was scored across 5 categories: SEO, GEO (AI search readiness), Performance, Security, and Accessibility.

The results are surprising. Many companies that sell SEO services have significant gaps on their own websites. The average security score was just 50/100. 1 tools scored below 70 on GEO readiness, meaning AI search engines may struggle to cite them.

Here's the full ranking, from highest to lowest overall score.

Key Findings

1. Security is the biggest blind spot

The average security score was just 50/100. Over half the tools scored below 50 on security. Missing Content-Security-Policy (CSP) headers was the most common issue — found on 25 out of 28 tools. SpyFu and Seobility scored 0/100 on security with zero security headers.

2. Most SEO tools are GEO-ready (but not all)

The average GEO score was 87/100 — respectable. KeywordTool.io and AIOSEO scored a perfect 100. But 1 tools scored below 70, primarily due to missing structured data or blocking AI crawlers. Seobility actively blocks GPTBot — meaning ChatGPT literally cannot reference their content.

3. Performance drags down top tools

Script bloat is epidemic. Diggity Marketing loads 107 external scripts. Jasper has 29. SEOPress, a tool that helps others optimize their WordPress sites, scored just 50/100 on performance with 27 external scripts. Only Serpstat (90) and KeywordTool.io (90) scored above 85 on performance.

4. Accessibility is a bright spot

Most tools scored well on accessibility (average 95/100). Ubersuggest, Moz, Semrush, FATJOE, and several others scored a perfect 100. The notable exception: Rank Math at 80/100 with 93% of images missing alt text.

5. The cobbler's children have no shoes

Companies that sell SEO and website optimization services don't always follow their own advice. Serpstat (an SEO tool) is missing its homepage meta description. AIOSEO (a WordPress SEO plugin) has a security score of 15. This is a known phenomenon — teams focused on building tools often neglect their own marketing site.

Methodology

Each website was scanned using Foglift's public API (GET /api/v1/scan) on March 16, 2026. The scanner analyzes 5 categories:

SEO (100 pts) — Meta tags, headings, structured data, sitemap, robots.txt
GEO (100 pts) — AI crawler access, JSON-LD depth, FAQ presence, entity markup, content structure
Performance (100 pts) — Script count, render-blocking resources, external assets
Security (100 pts) — HSTS, CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy, X-Content-Type-Options
Accessibility (100 pts) — Image alt text, heading hierarchy, ARIA landmarks, contrast, form labels

Overall score is the average of all 5 categories. Scans analyze the homepage only. Results may vary if sites update their configuration.

FAQ

Which SEO tool has the best GEO score?

KeywordTool.io and AIOSEO both scored a perfect 100 on GEO readiness. Ahrefs, Semrush, Moz, and several others scored 90. The key differentiators are structured data implementation and AI crawler access policies.

What is a GEO score?

GEO (Generative Engine Optimization) measures how well a website is optimized for AI search engines like ChatGPT, Perplexity, and Google AI Overviews. It checks AI crawler access via robots.txt, structured data depth, FAQ presence, entity markup, and content structure.

Why do many SEO tools have low security scores?

Most SEO tools are missing Content-Security-Policy (CSP) headers — the most common security gap in our benchmark. Many also lack HSTS, Referrer-Policy, and Permissions-Policy. These are simple server configuration changes that most teams haven't prioritized.

Can I scan my own website?

Yes — Foglift offers free scans at foglift.io. Enter any URL to get scored across SEO, GEO, Performance, Security, and Accessibility. No signup required.
