FAQ

Which code review tools are the most visible to AI search engines?

In our October 18, 2026 crawl, the top-scoring code review tools were SonarSource (98/100), Greptile (96/100), CodeRabbit (95/100). The score measures how easily ChatGPT, Perplexity, Claude and AI agents can crawl, understand and use each product's homepage.

How do code review tools compare with the rest of the AI Visibility Index?

The 8 code review tools we track average 87/100, 1 points above the 86/100 average across all 538 SaaS and AI sites in the index.

What is the most common AI visibility gap among code review tools?

75% of the code review tools we checked miss "Machine-usable interface (API / MCP)" (vs 52% across the whole index). Fix: Expose an MCP server or OpenAPI spec and link it from llms.txt so agents can use your product, not just read about it.

How is the AI visibility score calculated?

RankRoot checks four areas on each homepage: AI crawler access (robots.txt rules for GPTBot, ClaudeBot, PerplexityBot and others), answer-engine content (title, headings, FAQ-style content, server-rendered text), structured data (JSON-LD, Organization/Product schema) and agent readiness (llms.txt, discoverable API or MCP server). Each area is scored 0 to 100 and combined into one score.

When was this data collected, and can a company update its score?

Scores are a snapshot from our crawler on October 18, 2026. They are not updated automatically. Anyone can rescan a site live for free, and we refresh the index periodically.
