I’ve been experimenting with pulling public business data from Google Maps and enriching it with things like emails and owner information.

One thing I’m trying to figure out is which filters actually help identify businesses that are more likely to need marketing services.

For example:

• Rating
• Number of reviews
• How recently they received reviews
• Business category
• Website/no website
• Owner/contact information
• Location

For agency owners or anyone doing outbound B2B lead gen, what signals do you actually use before deciding a business is worth contacting?

I’m especially curious whether there are less obvious filters that have improved your response or close rates.
