Common questions
How was this commercial construction contractor list generated?
We asked ChatGPT, Google AI Overviews, and Perplexity the questions a customer actually types — such as "best commercial construction contractor in Duncannon, PA" — on August 13, 2026, then recorded every business each engine named. Nothing is ranked by us, paid for, or editorially chosen. A business appears here because an AI engine named it.
Why does the answer change when I ask myself?
Model outputs are probabilistic and shift with phrasing, session history, and model version. The same question asked twice can return different companies, which is why a single check is not evidence in either direction. What matters is which businesses appear consistently across engines and over time.
