Overview
PROCERT Building Approvals is an accredited building certification firm serving residential and commercial projects. Construction certificates, complying development certificates, occupation certificates, principal certifier appointments - they handle the full scope of building certification.
Strong business, strong referral network, experienced certifiers, solid reputation in the industry. But entirely dependent on word-of-mouth. When homeowners and builders started asking AI tools "how do I choose a building certifier?", PROCERT wasn't in the answer.
We partnered with PROCERT in early 2026. Within 6 weeks of the first AEO-optimised content going live: 82% AI prompt coverage, 11x Google impression growth, and 7 inbound leads driven by AEO content - from a channel that didn't exist 6 weeks prior.
“We've always grown through referrals - builders who know us pass our name on. That works, but it only reaches people who already know someone in the industry. Within a couple of weeks of the content going live, we had someone contact us directly through the website. That's a channel we didn't have before - and the enquiries have kept coming.
Omni Eclipse partnered with PROCERT Building Approvals on an AEO strategy. The first content launched in early 2026. Within 6 weeks, AI prompt coverage reached 82% across ChatGPT, Gemini, Copilot, and Google AI Overview. The same content also lifted PROCERT's traditional SEO performance - traditional Google search impressions grew 11x in the same period. Most importantly, PROCERT generated 7 inbound leads driven by the AEO content - a net-new channel that didn't exist before the engagement.
The challenge
-
Invisible in AI search. When homeowners and builders asked ChatGPT, Gemini, or Copilot "how do I choose a building certifier?", PROCERT wasn't in the conversation. Competitors and directory sites dominated the AI responses.
-
No inbound digital channel. PROCERT had grown exclusively through referrals and industry relationships. The website existed but wasn't generating enquiries - not because the business wasn't good, but because the content wasn't structured for how people now search.
-
Content gap. Existing website pages were service-focused (what PROCERT does) but didn't address the actual questions homeowners and builders are asking AI tools - "private vs council certifier", "how to choose", "what does a certifier cost". Those questions were being answered by competitors and generic content sites.
The approach
To make PROCERT the definitive building certification authority in AI search, we deployed our proven framework: The AI Visibility Flywheel - a four-step system designed to grow your visibility. The content was designed to work on both channels simultaneously - AEO-optimised content that also targets high-intent Google queries. One content strategy, dual-channel results.
The results
PROCERT went from invisible in AI search to being actively recommended across ChatGPT, Gemini, Copilot, and Google AI Overview. Within 6 weeks of the first content going live, PROCERT had achieved 82% AI prompt coverage and an 11x increase in Google impressions.
| Metric | Before | After | Change |
|---|---|---|---|
| AI prompt coverage | Negligible | 82% | Across tracked prompts |
| Google impressions | Baseline | 11x growth | Across AI + traditional search |
| Inbound leads from AEO | 0 | 7 | Net-new channel from AEO |
Traditional Google search performance: 11x impression growth
The AEO content didn't just drive AI citations - it simultaneously lifted PROCERT's traditional Google search performance. Impressions grew 11x from pre-content levels in the same window, with a clear inflection point visible from the moment the first AEO content went live.
7 inbound leads from AEO in 6 weeks
The crescendo: in the 6 weeks since the first post went live, PROCERT has received 7 inbound enquiries driven by the AEO content. Real people finding them, landing on the site, and reaching out directly. A net-new channel that didn't exist 6 weeks prior - and one that's still compounding as the content matures and AI models increasingly reference it.
Don't take our word for it - try the exact search yourself.
PROCERT now recommended by AI assistants for building certification searches - up from zero mentions before AEO.
The bigger picture
PROCERT's results prove that AEO works for professional services businesses that have always relied on referrals.
For service businesses, AI search is the first scalable inbound channel that actually converts. PROCERT didn't just get visibility metrics - they got 7 qualified inbound leads from a channel that didn't exist 6 weeks earlier. And the content that drove AI citations simultaneously grew their Google impressions 11x in the same period. One strategy, two channels, real revenue.
McKinsey's "New Front Door to the Internet" report found that 44% of consumers now prefer AI search for buying decisions over traditional search (McKinsey, Oct 2025). Gartner predicts traditional search volume will drop 25% by end of 2026. And AI search visitors convert up to 23x better than organic (Ahrefs, Jun 2025).
Most professional services firms - accountants, lawyers, consultants, certifiers - are still invisible in AI search. The window to be first in your category is open, but it's closing. PROCERT moved early, and it's already driving real enquiries.
