Can anyone suggest on how to increase adsense earnings for the website www.firsteducations.tk my earned now its very small 0,50 € per day.
What is your site about? To make this work you need to be in the competitive markets like financial, health and wealth. Plus you need a lot of traffic.
It seems that you are new in this field . I checked your blog and it seems very strange to me . Nothing best in that . Before starting any blog , you need to do lots of research . Also can you tell me how much traffic you get daily basis ? Working on SEO ? Lots of things must be there to earn through Adsense , its not an easy task . You need to learn lots of things , and only then you will be able to make a good start like $5 - $10 a day , but that is very far from you . Let me know if you need any type of help . I can easily help you in generating good income from Blogs .
Your site is good enough but I recommend you to use .com domain as it will helps you a lot for ranking different keywords.
the content on your blog should relate with what is available on the adsense ad, in short it should be a good quality content
Don't focus on earnings from the beginning as you have to focus on quality traffic and contents. About more earnings , target high paying niches, keywords that you are good to write.
Here are my two cents : More traffic=More earnings. So focus on traffic. Don't use other Ad networks like infolinks,along with Adsense. They will decrease your over all revenue. In order to get the best CTR, change the positions of your ads and inspect that what placement works the best for you.
^^ you can use multiple ad networks using as ads alternate to get best earnings. Like for search traffic AdSense , for direct traffic any other . or ads rotation.
Basically it's all about getting more targeted traffic, more targetered traffic the more adsense clicks you'll get.
