Listing all local businesses on certain area in Google Maps

Hello dear developers!

I'm currently in the process of doing a research that is going to require me to list all businesses in my city and compare how much percentage of them have a website.

Is this possible to do? Maybe using the Google Maps API? Any output would be acceptable, I can manage.

I've tried to use this http://ift.tt/2f0Bknr but without success.

I've read about the limitation of Google's API to be around 200 location searches (per-day?), but I think that'll be enough.
