Philadelphia foundation repair

Finding 01

Does ranking well on Google mean AI recommends you?

It helps, and it is nowhere near enough. Of the 22 best-ranked businesses in Philadelphia, 2 got named by an AI engine — 9.1%. Of the 22 ranked lowest, 0 did. The single most-named business in this market ranked 3rd on Maps, coming up in 10% of answers.

Google rank and AI answers are decided by two different systems looking at different things. Your map position comes from how close you are, what category you are in, and how people engage with your listing. Whether an AI names you depends on whether it can find, read and trust a description of your business in the sources it pulls from. Ranking first buys you better odds. It does not buy you the answer.

How many local businesses actually appear in AI answers?

Very few, and the ones that do take most of it. Of 66 businesses measured, 2 were named at least once and 64 were never named. The three most-named businesses took 100% of every mention in the market.

Finding 03

Are the best-reviewed businesses invisible to AI?

Often, yes. Take the 16 strongest businesses in Philadelphia — the top 25% once you combine Google rank, star rating and number of reviews — and 14 were never named by any engine. That is 87.5% of the best businesses in town, missing from every answer.

One of them ranks 12th on Maps with 5.0 stars, and was named zero times across all 50 answers. One of them ranks 27th on Maps with 4.9 stars, and was named zero times across all 50 answers. Their customers rate them highly and Google ranks them well. The AI engines do not know they exist.

Finding 05

Do ChatGPT, Gemini and Perplexity recommend the same businesses?

No. Asked the same questions about the same market, the closest any two engines came to agreeing was 60% of thebusinesses they named — and the furthest apart pair agreed on just 0%.

Each engine surfaced a different slice of the market: Perplexity named 5, Google AI Overview named 4, Gemini named 3, ChatGPT named 2, Claude named 2. Showing up in one does not mean showing up in the others, so checking yourself against a single assistant tells you very little.

How we measured it

Google Maps position, star rating adjusted for how many reviews back it up, and review count on a sliding scale that levels off around a thousand.

Scope

One market, one category. Every number on this page describes Philadelphia and comes from that market alone — results differ between markets and we do not carry them across. We never name individual businesses. AI engines change over time; this describes July 2026.
