AI visibility of Dunedin plumbers: the data.
We audited 22 plumbers’ websites in Dunedin. The average AI-visibility score is 67/100: 5% block at least one AI search crawler and 41% have no structured data — meaning ChatGPT and Google’s AI often can’t read the businesses they’re asked to recommend.

What are Dunedin plumbers getting wrong?
82% show no visible 'last updated' date
The fix: Display and maintain a visible update date — AI engines strongly favour recently-updated pages.
41% have no structured data at all
The fix: Add LocalBusiness JSON-LD so AI engines can identify the business, its services and its area.
5% block at least one AI search crawler
The fix: Allow OAI-SearchBot, Claude-SearchBot, PerplexityBot, Bingbot and Googlebot in robots.txt — training-only bots can stay blocked without losing citations.
0% serve their content only via JavaScript
The fix: Server-render the key pages — AI crawlers don't run JavaScript, so a JS-only site reads as a blank page.
Why does this matter for a plumber in Dunedin?
When someone in Dunedin asks ChatGPT, Gemini or Perplexity for “a good plumber near me”, the engines recommend from the businesses they can actually read and verify. With an average score of 67/100, most of the local market is effectively invisible to those answers — which means the few businesses that fix their basics take a disproportionate share of AI recommendations. That gap is the opportunity.
Compare: the national average for plumbers is 70/100 across 256 sites.
