Google Maps may sometimes add additional categories of listings to your search depending on the specificity of your search and location. For instance, when searching using the “restaurant” keyword, you may also be presented with other similar results, such as cafes, bars, coffee shops, or other venues. This could potentially yield leads that aren’t as relevant when using more specific search terms such as tennis courts.
You can ignore those entries and select the leads that are most relevant to your search when choosing which leads to add to a list.
