First of all get to know adwords,it’s very good to know what’s behind adsense.
Write pages based on top paying keywords,on this pages top paying adsense ads will be shown and you will end up earning more through adsense.
Use keywords in english language,most of the websites are in english.
Put your ads on a strategic place,these are places that are eyecatchers.
This way people will have the intention to click faster on your ad and your click through rate raises.
Also make sure your ads blend in with your web page,they better have the same colors as the template you are using.
This way you will prevent advertising blindness.
While gathering info about links I found out that blue is the best option for links,it’s some sort of a standard option so people will click it faster.
Also it’s better to make the url the same as your ad text,this way your url “melts” into your ad text.
All this will get you a better CTR(Click through rate)
