Five rows from the full 132-row dataset, sorted by rating & review count. The full file has one row per business with 16 columns: business name, email, email type (business or personal), phone, street address (with postal code), city, state/province, country, Google rating, review count, website, email quality, audit date, and any other emails and phones we found for the business with where we found them. The CSV adds email_2, email_3… where a business has more than one address. Service-area businesses (mobile mechanics, handymen, cleaners) deliberately don’t list an address on Google, so that column is blank for about 2% of rows.
