Which LLM is best for SEO?

No single LLM is flatly best for SEO, since each excels at a different part of the workflow. OpenAI's GPT models and Anthropic's Claude tend to produce cleaner long form drafts and handle nuanced instructions well, which helps with content writing.

Google's Gemini has a practical edge for keyword and SERP research since it integrates directly with Google's own search data and Search Console in some workflows. None of them replace dedicated SEO tools for crawling, backlink data, or rank tracking, which still require specialized software.

The realistic setup for most teams pairs one strong LLM for drafting and analysis with purpose built SEO or GEO software for the technical and measurement side.

That is the gap our GEO softwarefills alongside whichever LLM you already use.
