Frequently Asked Questions

Which agency is best for ChatGPT optimisation?

Onely leads at 9.3/10 with real-time ChatGPT tracking and deep crawler expertise. First Page Sage (9.1/10) pioneered ChatGPT work with a Bing-first approach. iPullRank (8.8/10) handles Fortune 500 ChatGPT visibility from £8,000+/month.

How does ChatGPT decide which brands to cite?

ChatGPT uses Bing as its search index. If you are not in Bing, ChatGPT cannot find you. The top citation factors are YouTube mentions (0.737 correlation) and brand web mentions (0.664). 44.2% of citations come from the first 30% of a page. 76.4% of cited pages were updated within 30 days. 71% use schema markup.

Is ChatGPT optimisation different from general AI search optimisation?

Yes. ChatGPT uses Bing, not Google. It has its own crawlers (GPTBot, OAI-SearchBot, ChatGPT-User) and distinct citation patterns. But many signals overlap. Brand authority, entity consistency, and structured content help across all AI engines. A ChatGPT specialist makes sense if ChatGPT drives most of your AI traffic.
