Can ChatGPT do SEO?

It can do parts of it well. I use ChatGPT and Claude daily for brainstorming and quick data analysis. For the barbershop project I built the whole single-page site with AI tools in an afternoon. That used to take me days.

But if you just ask an LLM for SEO advice cold, even Claude Opus 4.7 or ChatGPT 5.5 will confidently hand you tips that is not working or is non existing for the last three years. I still see them daily: "add FAQ schema for more SERP real estate," recommendations that assume Google shows 5–10 FAQ answers in results, advice built on rules that died. None of it true anymore.

The model doesn't know what's been deprecated most of the times, it just predicts text that sounds like SEO. So you have to verify everything it gives you against current SERPs, current Search Console data, and current documentation.

What it genuinely cannot do on its own: cannibalization by default or make business-level decisions without proper data, guidance and prompting As an assistant with a human checking its work, it's a massive speed-up. As a replacement for the thinking part, it can produce forgettable, often outdated or hallunicated stuff if not double checked.
