Are you using AI for your content or keyword analysis? Then it's time to discover what it can really do – and where it falls short. In Previsible's first comprehensive AI SEO Benchmark, Claude Sonnet 3.7 emerges as the strongest model. However, that is no guarantee for flawless SEO.
When AI Performs – and When It Doesn’t
Claude scores 83% on a test with 50 objective SEO questions, surpassing competitors like Gemini, Perplexity, Copilot, and ChatGPT. However, the human SEO specialists from the Previsible team performed better, with an average score of 89%. The difference lies not in speed or output, but in experience, insight, and collaboration across disciplines.
Claude and other LLMs excel primarily in content tasks, where the average score is 85%. Tasks such as drafting content briefs or identifying internal linking opportunities can be effectively outsourced to AI. However, for technical SEO, AI only scores 79%, and for e-commerce SEO, it is even lower at 63%.
Another noteworthy observation is that popular features like "in-depth research" or web search tend to be counterproductive, reducing the accuracy of the answers. Only adding a persona such as "you are an SEO expert" results in an average improvement of 2.8%. AI models excel at predicting text, but this makes them probabilistic. They know nothing with certainty. And that is precisely why it is better not to use them for a technical site audit or migration.
Consequences for your SEO strategy
AI is useful, but not autonomous. There are no reliable AI agents that can execute SEO tasks from start to finish. AI generates answers, but does not carry out strategy or project management. The strength lies in support, not in replacement.
For companies, this means that AI must be used wisely. Use it as a supplement in content development. Think about structure, keyword opportunities, and quick analyses. Leave strategic choices, technical execution, and collaboration to people. To be prepared for what’s to come, visibility in AI output is just as important as in Google. Tools like Peec.ai help you see if your brand is visible in LLM responses. This way, you can discover where content opportunities lie in relation to your competitors.
