I need to tweak some setting but I don't know how to, is it my daily budget? It's currently $4 a day, is that too low? How do you find out which country/city has the most number of webmasters? I'm selling webmasters stuff, php scripts etc.
$4/day? Try using like $200.. you won't pay that much, but you'll get more impressions and clicks then... - Chris
Its not working... I tried everything. My keyword is PHP script, US targeted. And now it says that the ads are not showing. CPC is pretty High, and the daily budget is around 20 bucks
so when you search for "php script" is your ad even showing up? It could be just you're not bidding enough, or your QS is bad and you need to streamline that more
