I have lot of Ad's on many different web pages, not to make money but just track visits and possible clicks. Most of people hate google Ads and never click on those! Only those pages that trick customers into clicking those. I also noticed right before $100 the not adding any revenue! Even I sometimes get clicks.
Google got to powerful and lazy and should be broken up by the Gov!
I don't know how those European companies can be so unorganized with basic functions like collecting payment and customer info! I think a company working out of garage would do a better job! Booking.com is not even able to collect full address from a customer at the time of booking! I can do this with a $10 webpage form. Not collecting basic info let customer put fake credit card info is a source and heaven for criminals and bad people booking trought the site! Looks like the corporate office in Amsterdam does not know what the are doing!
