How list sources are chosen
The businesses on a list are map data. The source recommended for the complete list follows one rule, the same for every page.
What a source must do
To be recommended for the complete list, a source must take a search such as “dentists in London” and return business rows with a phone number and a website column in its published output schema.
How sources are ordered
Each eligible source scores points for the columns in its published schema that a list buyer needs most:
| Column in the schema | Points |
|---|---|
| Emails | 4 |
| Phone numbers | 2 |
| Websites | 2 |
| Star ratings | 1 |
| Review counts | 1 |
| Opening hours | 0.5 |
| Social profiles | 0.5 |
| Number of columns (40 or more scores the full point) | up to 1 |
| A ready-made example setup on the Store | 0.5 |
The highest score is the best fit. A second Google Maps source and a Yelp source (where Yelp covers the country) are shown as alternatives, and a few sources specific to one kind of business are added where they fit, such as a menu source for restaurants or an official register.
What is never used
- Payment. Nobody can buy a position.
- Who publishes the tool.
- Claims we cannot check: a column only counts when it is in the published schema, and a schema column does not guarantee a filled value.
