My AdSense Revenue is declining continously in the past Three Months

I have noticed that my adSense Revenue is getting reduced lot in the the past Three Months.
I use my Adsense account in many of our different websites, blogs, Forum and YouTube Channel.
Not much traffic change in our sites. I couldn't understand the reason for this drastic reduction in adSense revenue.

Any solution to fix this problem? Anyone else face similar problem?

 

It can happen by time, Adsense not giving much ernings when acc comes old.

 

I don't agree with you. It didn't happen with me in the last 4 years. My earnings are consistent.

 

Analyze your traffic, check what is going wrong. Optimize your content by using better titles. Promote your articles on social media sites.Changing ad placements or using different ad blocks will also work.

 

Thanks for your suggestions. I understand that your suggestions will be helpful to increase the revenue.
But right now, I would like to know why the revenue is decreasing without making any change in sites.

 

I would change up the ad placements and see of that makes an improvement. I believe that Adsense might see it as getting stale and you will make less. It's just a theory but also something that I have noticed on my own sites over the years.
