One of the most common surprises when brands first use Lighthouse is how much their visibility varies across AI platforms.

Key Takeaways
  • The same brand can score 70% on ChatGPT and 20% on Claude — same prompts, wildly different results
  • Each AI platform has its own personality, training data, and biases
  • Perplexity responds to content changes fastest; ChatGPT is the slowest to update
  • Your AI visibility strategy needs to be platform-aware

This isn’t random. Each AI platform has different training data, different retrieval capabilities, and different behavioral tendencies.

ChatGPT (OpenAI)

ChatGPT has the largest user base and tends to be the most “mainstream” in its recommendations. It favors well-known brands and tends to list multiple options.

Tendency: Lists popular options, balanced tone, moderate detail per brand.

Claude (Anthropic)

Claude tends to be more analytical and nuanced in its responses. It’s more likely to qualify its recommendations and discuss trade-offs.

Tendency: Detailed analysis, source-heavy, acknowledges limitations.

Gemini (Google)

Gemini has the advantage of Google’s search infrastructure. It frequently grounds its responses in live search results.

Tendency: Search-grounded, current, links directly to sources.

Perplexity

Perplexity always uses live search and always cites its sources. This makes it the most transparent and the most responsive to content changes.

Tendency: Citation-heavy, real-time, heavily influenced by current web content.

What This Means for Your Strategy

Don’t treat AI visibility as a single number. Each platform is its own channel with its own dynamics. Use Lighthouse’s per-platform breakdown to identify which platforms you’re strong on and which need work.
