Pricing page should list how many visitors each plan serves
Your web site should list front and center, on the home page and the pricing and plans pages, how many visitors each plan serves...
E.g., 17/month ... 30-40k visits monthly
34/month ... 100k monthly, etc
This info is not easily found and it is frustrating.

This depends completely on the type of application u are trying to host so this is not a given they can share....
