What does an AI SEO agency actually do?

The term "AI SEO agency" is increasingly used across the UK digital marketing industry, but what the work actually involves is poorly understood. Many agencies have added "AI" to their service descriptions without fundamentally changing their approach. Understanding what a genuine AI SEO agency does — and does not do — helps you evaluate whether you are getting real value.

A genuine AI SEO agency focuses on how AI platforms interpret your business. This is distinct from traditional SEO, which focuses on how Google ranks your web pages. The platforms are different (ChatGPT, Google Gemini, Perplexity, Claude vs. Google Search), the mechanisms are different (answer synthesis vs. page ranking), and the optimisation strategies must be different too.

The core activities of an AI SEO agency include: entity analysis — determining how AI platforms currently define your business and identifying inaccuracies or confusion; structured data implementation — ensuring your website provides machine-readable signals that AI platforms can parse accurately; ecosystem validation — auditing and aligning your presence across directories, social profiles, and third-party platforms; content architecture — structuring your content so AI platforms can extract relevant answers to specific queries; and citation tracking — measuring how frequently and accurately your brand appears in AI-generated responses.

What an AI SEO agency should not be doing: simply repackaging traditional keyword research as "AI-optimised content," running Google Ads and calling it AI marketing, or making promises about "ranking on ChatGPT" (AI platforms do not rank pages in a list).
