You write: “Why would hair salons in San Jose get vastly more ratings than car washes in San Jose, which also get vastly more ratings than photographers in San Jose?”

Let me try to address this. It’s more likely that someone would store a phone number for a hair salon to set up an appointment than the phone number or address of a car wash. As far as photographers, it turns out there are more implicit recommendations for photographers than car washes…one just has to scroll down to see the full list of photographers (we are modifying the correlation between query term and business categories so that these results will show further up). Hope this helps. Look forward to your continued coverage and review of grayboxx.
