About the Project
- Industry: HVAC (residential and commercial)
- Target market: California
- Service: AI SEO / GEO
- Engagement timeline: May 2026 – November 2026 (6 months)
Our Goal
Get the company cited and named in AI answers for high-intent HVAC queries, ahead of third-party sources.
We prioritized decision-stage topics where homeowners use AI answers to shortlist options before they call a contractor: replacement costs, ductwork pricing, and AC brand comparisons.
Success was measured by brand mentions and citations across AI platforms (Ahrefs Brand Radar), plus organic clicks and impressions on the same topics (Google Search Console).
The Challenge
- Third-party sources dominated AI answers. Queries like “air duct replacement cost” and “most reliable AC brand” were answered from aggregators and publishers.
- Cited, but not named. AI answers linked to the site as a source but rarely mentioned the brand by name.
- No visibility outside Google. Zero mentions in ChatGPT, Perplexity, and Copilot.
Execution
Baseline and Tracking
- Built a prompt set and set up tracking in Ahrefs Brand Radar
Answer-First Content
- Built new info pages (e.g., duct replacement pricing, top AC brands) with the answer and price range in the first lines, a pricing table by home size, and an FAQ block
Entity and Schema
- Added Organization, LocalBusiness, Service, and FAQ markup with sameAs links
- Aligned brand name and NAP across the site, GBP, and directories
Technical Access
- Checked robots.txt and WAF rules for AI and search crawlers
- Set up Bing Webmaster Tools and IndexNow, since ChatGPT and Copilot rely on Bing’s index
Citation-Source Building
- Built presence on third-party sources AI engines already cite for target prompts (directories, review platforms, industry publications)
Freshness and Proof
- Updated pricing data and dateModified on cost pages
- Added original price ranges AI can quote
Prompt Expansion
- Added new prompts from responses where the site was found but not cited
