AI Search Engine Visibility
How Purely Air Tech Ltd achieved a perfect AI visibility score using Technical Graffiti.
Purely Air Tech Ltd are an integrated mechanical services company based at Milton Park, Abingdon, Oxfordshire. They specialise in HVAC design and installation, VRF systems, compressed air and ventilation for commercial laboratories and offices across the UK. Founded in 2016, they are a Daikin D1 Business Partner with over 35 years of combined experience.
Their project portfolio includes work for Dyson, Air Canada Cargo at Heathrow, and biotech companies at Milton Park. They operate entirely on referral — no advertising, no cold outreach.
Despite an established reputation and high-profile clients, Purely Air Tech were invisible to AI search. When potential clients — or their referrers — verified them using AI tools like ChatGPT or Google Gemini, Purely Air Tech did not appear. No schema markup. No llms.txt. No meta description. AI engines had no way to identify, classify or recommend them.
A referral-based business depends on trust. If someone is referred to you and searches to verify who you are, AI giving no result is the same as a bad result.
