Which LLM is best for SEO?

No single LLM is best for SEO; each wins a different job. Claude is strong for long-form drafts that need consistent voice. GPT models are reliable all-rounders for briefs and meta tags. Gemini connects to Google's index, and Perplexity is the researcher, returning cited sources.

As for whether LLMs are good at SEO overall: good at production, weak at strategy. They draft fast but cannot pick winnable keywords, and raw output reads generic enough that readers and detectors notice.

For SEO content writing specifically, Claude and GPT trade the lead depending on the prompt and the edit pass that follows. Pick a model for writing; keep humans or purpose-built systems for keyword selection and editing.
