GA and AdSense both seem to measure things differently depending on your cookie setup. Read that discussion, and check your Cookie Consent implementation.

OK thanks I will implement it

@not2easy

What if I decide not to show non personalized ads.. Do I still need to activate those consents

@Prince112
If the European GDPR regulations apply to you, then yes you need a cookie consent banner. As to the question of whether GDPR applies to you, only you can answer that for sure. But if you are located in the EU, it certainly does or if you get significant portion of your traffic from the EU it likely does as well. Anything else becomes a legal matter that is related to your jurisdiction. If you don't want to take any risk just apply the cookie consent banner.

As to the problem you describe in your OP. I'm not sure that this will solve your problem but I'm not sure I understand the problem. If you are getting 19 clicks from 23 pages views, then the issue will not be solved with a cookie banner. Instead you need to find where the traffic is coming from and block it.

I just check in now ..it's now 47 click from 59 page views and its seems so inappropriate .. I can't block traffic from UK because my site is hosted there.. I can't tell if its all these site monitoring bots from my host but I'm sure bots can't get past consent..is there any other solution?

You obviously can't block all traffic from the UK. What you need to do is find the IP addresses that are doing the clicking and block those, assuming that this is a bot or malicious actor, then there will likely only be 1 or 2 to IPs to block. Good luck.

If you are sure that these are invalid clicks, you can proactively advise AdSense by reporting invalid click activity.

@NickMNS

The issue seems to have been resolved after activating European GDPR privacy message..

My ads and traffic align quite well now. Some of these hosts providers can cause problems with their monitoring activities especially if you show video, anchor or gif ads .. Their monitoring I.p can access the site automated ads will load .. I usually don't have this issues until I activated animated ads

I'm happy to hear that your problem is solved!

Thanks I appreciate your help
