James Dooley: Why SEOs are switching from ChatGPT over to Claude for Chrome. Today I am joined with Dennis Yu, who has done a lot of split testing on all the different types of LLMs to be able to get those AI agents working 24/7. So Dennis, the question for you today is why should SEOs be switching over from ChatGPT to Claude?

Dennis Yu: Well, James, there is no question that ChatGPT has a consumer advantage with over a billion monthly users. But in 2026, Claude went from 25 per cent market share to 70 per cent market share in business. So for those of us doing SEO as business to business, on behalf of other businesses, businesses want to get work done. It is not just about chatting.

All the processes we use for building sites, recording content and running tools have changed. In the last couple of months you may have seen things like Claude dispatch, co-work, and Opus 4.6 with a million token context window. There was even a period where Claude doubled token credits outside core hours.

In the last week, James, I burned 150 million tokens and it cost me $200 a month. What did I get done? I created about 600 articles. I linked together a network of sites. We got 10 new clients. I wrote three books. I processed podcasts. I had it send emails on my behalf.

I was on a call with a private equity firm helping a client sell their company. The AI even wrote the foreword to a book. It was so good the client read it out loud. That is the level of output we are talking about.

So if you are an SEO, you need to level up as a manager. Claude allows you to do that because it is built around orchestration. Tools like Claude Code and what people call the harness let you manage multiple agents. If you have strong processes, documentation and results, then paying $200 a month while using $15,000 worth of compute makes it an easy decision.

James Dooley: And how much would that cost if you were doing the same thing with ChatGPT? Or would it just time out?

Dennis Yu: I use Opus 4.6, which has a million token context window. Input costs about $5 per million tokens and output is $25 per million tokens. I will likely burn close to a billion tokens this month. That is easily $25,000 worth of usage. That is just one agent, and I have multiple running.

James Dooley: So if someone is currently using ChatGPT and thinking about switching, especially if they want to replace manual work with automation, why is it better to use fixed subscriptions instead of the API?

Dennis Yu: Because API costs escalate fast. This is similar to when companies burn money to gain market share. That is what Claude is doing right now against OpenAI. You might as well take advantage of it.

For migration, ask ChatGPT to export everything it knows about you. All conversations, workflows and SOPs. Store that somewhere safe. Then use that to train your Claude setup.

A lot of people think they have a relationship with ChatGPT and do not want to leave. But once they transfer everything, Claude picks it up quickly. The difference is Claude handles longer workflows because ChatGPT agent mode times out after about 30 seconds.

That means anything multi-step or long-running becomes frustrating. It used to work better, but now it struggles with sustained execution. I still test both, but Claude consistently handles deeper tasks.

James Dooley: Yes, that lines up. Anyone using ChatGPT casually might prefer it. But if you are an SEO trying to produce work, Claude is far more powerful. I have done exactly what you said. I exported everything, moved it into Claude, and now I have multiple AI agents running. The productivity difference is massive.

So Dennis, it has been an absolute pleasure. Hopefully anyone watching this now looks at switching from ChatGPT to Claude and becomes far more productive.
