Frequently Asked Questions

Which AI SEO agency is best for Gemini visibility?

Found measures Gemini citations alongside ChatGPT and Perplexity with the deepest UK infrastructure. Charle and Impression both track Gemini for client programmes. CarrieAnn Sudlow is the boutique pick for founder-led teams optimising for Gemini and ChatGPT together.

How does Gemini choose its sources?

Gemini pulls heavily on Google's existing infrastructure: Knowledge Graph, organic ranking signals, structured data, and entity authority. Brands already strong organically on the underlying query usually appear in Gemini answers. The optimisation work overlaps with traditional Google SEO foundations.

Is Gemini worth separate optimisation from Google AI Overviews?

Mostly no. The underlying signals are largely shared. The marginal Gemini-specific work is in conversational query intent (Gemini answers run longer and more conversationally than AIO snippets) and in structuring content to be quoted at length rather than as one-line snippets.

How do I measure Gemini visibility?

Run target queries through Gemini and log brand mentions plus cited sources. Specialist agencies do this at scale. Found publishes Gemini citation share alongside ChatGPT and Perplexity for client programmes.

How much does Gemini-focused AI SEO cost?

£1,500 to £5,000 a month. Like other platforms, Gemini work sits inside a broader cross-platform programme since the underlying optimisation overlaps heavily with ChatGPT and AI Overviews work.
