When AI engines like ChatGPT, Claude, and Perplexity answer questions about plumbers in Penrith Sydney, Service Today comes up most often, appearing in 37.5% of AI responses and cited as a source in 62.5% of them. In House Plumbing and Metropolitan Plumbing round out the top three. Across 20 brands tracked, that gap between first and second place is significant enough to reflect a real difference in how AI engines perceive authority in this local market.
The rankings reflect which sources AI engines trust most when forming answers. Google.com dominates citations, which means business profiles, reviews, and Maps listings carry heavy weight. The other top cited domains are specialist local sites like shipwayseffectiveplumberspenrith.com.au, penrithplumbing.net.au, and mrsplashplumbing.com.au. These are direct business websites rather than aggregator platforms, which suggests AI engines here are pulling from brands that have built strong standalone web presences with locally relevant content.
For a buyer using this page, the practical takeaway is to cross-check AI-favoured brands against recent Google reviews specific to Penrith jobs, not just company-wide ratings. AI engines weight third-party validation and locally specific content, so a brand ranking highly here is likely one that has consistent recent reviews and pages targeting Penrith suburbs directly. That kind of local topical authority is harder to fake and tends to correlate with genuine service presence in the area.
At a glance
What we observed in this categoryauto-generated
Service Today dominates the Plumbers in Penrith Sydney category with a visibility score of 37.5% and a citation rate of 62.5%, producing a composite score of 45.0. Every other brand in the top 10 sits at 0.0% visibility and a composite score no higher than 3.8. This gap is not marginal. Service Today is the only brand Google AI Mode actively surfaces in response to queries, while 19 other tracked brands are effectively invisible in AI-generated answers.
In House Plumbing and Metropolitan Plumbing each hold a 12.5% citation rate despite recording zero visibility. This divergence means Google AI Mode references those two brands in sourced content but does not name them directly in generated responses. Brands ranked 4 through 10, including Reactive Plumbing and Electrical, Laser Plumbing, and Fix-It Right Plumbing, register zero on both metrics, meaning they are neither named nor cited in any AI-generated output observed in this audit.
The top cited sources list reveals Google AI Mode is anchoring heavily on local Penrith-specific domains such as shipwayseffectiveplumberspenrith.com.au, penrithcityplumbingservices.com.au, penrithplumbing.net.au, and mrsplashplumbing.com.au. The trade directory hipages.com.au also appears, suggesting the AI draws on aggregator pages alongside direct business sites. Servicetoday.com.au is the only tracked brand domain appearing directly in the cited sources list, reinforcing its position as the sole brand with meaningful AI presence in this category.

How to read this ranking
Four things worth knowing before you act on the numbers above. These are the same definitions across every industry page — for category-specific observations, see the What we observed section above (where available) and the per-brand insights inline in the ranking.
Visibility = being named

Citation rate = being trusted
Citation rate is the share of AI answers that include the brand's domain as a clickable source link. This is what the AI treats as authoritative evidence, different from being named. More on citation rate →
Top engine differs by brand
The "top engine" column shows which AI surface each brand performs best on. Big gaps between a brand's score across engines usually points to specific content or schema gaps. How AI engines pick sources →
