Best ChatGPT SEO Agencies UK 2026
Last updated: April 2026 | Based on public information, published methodologies, and client outcomes
ChatGPT is where most people first encounter AI search. When someone asks ChatGPT to recommend a business, the answer draws on a combination of training data, Bing search results, and real-time web browsing. Getting your business into those answers requires a specific approach.
The Bing relationship matters. ChatGPT uses Bing as its primary search backend for real-time queries. That means Bing indexing, Bing Places listings, and structured data that Bing can read all influence whether ChatGPT recommends your business. Most traditional SEO agencies optimise exclusively for Google and miss this entirely.
Assessed on: understanding of the ChatGPT-Bing relationship, multi-platform testing (not just Google), practical methodology for ChatGPT visibility, and published results or case studies.

Why ChatGPT Optimisation Is Different
Most SEO agencies optimise for Google. ChatGPT uses Bing. That single difference changes which signals matter. Your Bing Places listing, your Bing Webmaster Tools setup, your IndexNow implementation, your structured data that Bing specifically supports - these all feed into whether ChatGPT can find and recommend your business.
Beyond the Bing pipeline, ChatGPT also relies on its training data and browsing capability. Content clarity, entity consistency across the web, and authoritative citations all influence how ChatGPT talks about your brand. A good ChatGPT SEO agency understands all three layers.
