Why my AdSense earnings so low?

first and only one important thing for adsense user is High Traffic

If you get high traffic so the CTR is high and the chance of click on ads is bright so ur income is getting rich

Try Experimenting, Change the ad location if you are not getting any results! the only reason why you are not earning is placing ads in the wrong place! For Example, if you have traffic from mobile users more...Don't Place an Ad on Sidebar Since it won't reach the mobile users.....

I suggest you to not depend on Google Adsense.

You have give lots of time to make earning from that.

So don't waste your time in Adsense and try some points I mentioned below.

Try to registered user by email newsletter or use singup to get a audience data.

After that try to approach some gaming product company for email marketing their product with your data.

Sell your own gaming product if possible or type with some thrid party to sell there product on your website.

One more good option is join a amazon affiliate marketing program sell product related your content.

Hope this help. If you need any help you can ping me.

Many countries are having low cpc rates like 0.01 $ per click or even less. You should try to increase your traffic and focus on US/UK/Canada traffic, they are having high cpc rates. CPC rates are also dependent on keywords which you are using in the articles. First do proper keyword research. Adsense is mainly for high traffic blogs, which will give you good CTR.

For low but targeted traffic blogs, sometimes affiliate marketing works.

You should try other ad networks , they may pay better

People are not earning like 10 years back with Google Adsense. Try other monetization platforms like Infolinks etc. If you have a blog with great content, then you will get offers for sponsored posts from companies.

If you having low earning, then start to targeted tire 1 countries traffic such as USA, UK, France, Netherlands, etc.

You will achieve high CPC.
