AI SEO: LLM Optimzation, AEO, GEO Google AI Overviews Case Studies

LLM · AEO · GEO · AI Search Optimization · 10 Industry Case Studies

ChatGPT. Perplexity. Claude.
Google AI Overviews.
They're Sending Thousands of Customers to Our Clients.

The AI search revolution is not coming — it has arrived. ChatGPT sends referral traffic directly into Google Analytics. Perplexity cites businesses as authoritative sources. Google AI Overviews replace blue links entirely. We optimise businesses to dominate every single AI engine. Here's the proof, industry by industry.

After full AEO / GEO / LLM optimisation across all AI engines: monthly AI-referred sessions grew from 106 to 1,840+ sessions. Revenue from AI sources scaled from £132 to over £4,200/month. ChatGPT engagement rate remained above 67% — the highest of any channel. This is what systematic AI optimisation looks like.

The Proof Is Already In Your GA4

ChatGPT Already Ranks as a
Top Traffic Source
for Our Clients.

This is not a theory. The GA4 screenshot above shows ChatGPT appearing as the 3rd and 6th largest traffic source out of 25 channels — before we even began optimisation. After a full AEO / GEO / LLM campaign, that number scaled to over 1,840 monthly AI-referred sessions from ChatGPT, Perplexity, Claude, and Google AI Overviews combined.

The chatgpt.com/referral traffic shows a 67.74% engagement rate — nearly double Google organic. These visitors arrive with trust already established because ChatGPT personally recommended this business. That's the highest-intent traffic available anywhere on the internet — at zero cost per click.

After full optimisation: £4,200+ monthly revenue from AI channels alone. Growing every single month. Zero paid AI platform spend.

The question isn't whether AI engines send traffic. The question is whether ChatGPT, Perplexity, Claude, and Google AI Overviews are sending that traffic to you — or exclusively to your competitors.

The Window Is Open. Not For Long.

Your Competitors Are Not Doing This Yet.
That's Your Advantage. Right Now.

In 2012, businesses without social media were invisible. In 2016, businesses without mobile-optimised websites lost half their traffic overnight. In 2020, businesses without Google My Business missed the local search revolution entirely.

We are in that same moment right now — except the scale is vastly larger. ChatGPT alone processes over 100 million queries per day. Perplexity and Claude are growing at exponential rates. Google AI Overviews is appearing on over 90% of commercial searches. The businesses that get into these engines now — as citations, as recommended sources, as trusted entities — will own positions that compound in value for years.

Our client's GA4 already shows £132 in revenue from just 31 ChatGPT referral sessions — before any optimisation. After systematic AI optimisation, that became £4,200+/month from 1,840+ monthly AI sessions. At £0 per click. And growing.
