Q: Google Charge on Landing Page Click to Call
1. How much Google charges if someone calls within my landing page with a Click to Call Button?
2. Does Google provide Click to Call extension for Banner Ads on Display Network and Remarketing?
Re: Q: Google Charge on Landing Page Click to Call
To answer your questions:
1) You do not get charged for a click to call that is on your landing page. If you are referring to the call extension on mobile then the charge will be for one click of your ad.
2) No, your banner ads do not sow extensions only your text ads.
