Frequently Asked Questions
Which agency is best for ChatGPT optimisation?
Onely leads with 9.3/10, offering real-time ChatGPT citation monitoring and the deepest technical understanding of how ChatGPT's crawlers work. First Page Sage (9.1/10) pioneered ChatGPT optimisation with their Bing-first approach. For enterprise, iPullRank (8.8/10) handles Fortune 500 ChatGPT visibility at $10,000+/month.
How does ChatGPT decide which brands to cite?
ChatGPT uses Bing as its search index, so Bing visibility is the foundation. Beyond indexing, the strongest citation factors are YouTube mentions (0.737 correlation), brand web mentions (0.664), and entity consistency. 44.2% of citations come from the first 30% of a page, and 76.4% of cited pages were updated within 30 days. Schema markup is used by 71% of cited pages.
Is ChatGPT optimisation different from general AI search optimisation?
Yes. ChatGPT uses Bing as its index (most SEO agencies only optimise for Google), relies on specific crawlers (GPTBot, OAI-SearchBot, ChatGPT-User), and has distinct citation patterns. However, many signals overlap — brand authority, entity consistency, and structured content help across all AI engines. A ChatGPT specialist makes sense if ChatGPT generates most of your AI referral traffic.
