hello, it's my rate for google today: 4 Click 190 impermission But 0.01$ Also yesterday i have 4 click for 200 impermission but 0.17$ What's problem?
Some niches don't pay much and the value of the click depends on number of factors including user location, add location etc so I guess you need to see from where you traffic is coming from. Also, research some high value keywords for you niche and add content related to that keyword on your site to increase your chances to earn better.
It possible that you ad may need to incorporate more keywords into your PPC Ad or you may need to improve on your sale copy!
If all the clicks came from the same visitor, google may have not credited you for some of them because they suspected click fraud ("invalid clicks" - it doesn't have to be you who clicked on them).
Atleast you have got few clicks, I am not even gettign a single click for lots of impressions and I am really disappointed with it.
