Adsense CPC has gone down

The CPC has gone down by as much as 50% for my site in the last couple of months, while the visitors location has not changed, is this normal or should i be doing something

 

You lost a higher paying advertisers. They may have seen your site as not the right target.

 

Then we should try for another best option to earn money as I am earning $10 by just clicking on 6 clicks only.

 

Adwords has such option? I think it works on the conversion rate.

 

What kind of traffic does your site get? How much? What geo's? have you changed anything about your site? Added more ads? Changed up placements?

It works on a combination of CPM, CPC, and Conversions.

 

it is completely normal for CPC to go up and down. Maybe next month it will be better.

 

If you are comparing it to Nov/Dec results, it will likely be lower. CPC always goes up for the holidays
