So I just set my account up today. My (parked domain) AdSense for Domains has made money. But my other website which is actice and has had multiple page impressions and ad clicks has made no money what so ever. Why is this? How can I fix it?
I think either you are getting invalid clicks or its just a low paying keywords for you, so lookout for the niche
Mjewel is right, either someone with a "no-pay IP"(could be you) is clicking the ads (this means someone is constantly clicking ads at an abusive rate, publishers do not receive any money for this user's clicks) OR your eCPM is sooooo low that you aren't making anything, I have seen this multiple times when i'm starting sites or facebook apps.
You are more than likley getting invalid clicks, Just to let you know that if you click your own ADS that won't get you far either accept a ban by adsense. If i was you i would try some other types of keywords.
maybe you are getting invalid clicks. you can add more relative contents so that you can get good clicks
Perhaps you are getting invalid clicks or you are having very low paying niche so look for it and add nice contents to your site
It's possible that those are invalid clicks. I also encountered that situation. I got more clicks from same IP and got low income. Then google email that there is/are invalid clicks on my blog.
