I used to make like 0,50$+ each click but for example yesterday, i got for 5 clicks just 0,05$.. for 5 clicks! Anyone knows whats going on or what the cause might be?
Adword is what you use to put your website on adsense. Pretty much the exact opposite of Google Adsense. There are a lot of guides online on how to use it, here are just a few i found helpful: The best one: http://www.sitepoint.com/adwords-select-parts-1-4/ Also interesting: http://www.redflymarketing.com/adwords-tutorials/
It's all depends on the competition,days and time period. If you are running your campaign in Off season, then it will have low competition or else though the competition is high, it will be running on a particular period.
can you check and compare the clicks you got from today to rest of days and try to figure out a pattern ? You should look for specially the country from where the click originated and the page where the visitor was. Also it can be a Christmas effect , many ads are disabled after Christmas season is gone which will lead to a lower CPC.
There are alot of factors that can determine your CPC rates for example the country that your visitors are forum to the niche of your website. I have noticed that even in high tiered countries the CPC rates can be terrible. I would recommend analyzing your traffic and then maybe switching to CPA offers. Regards, Luke
