Google adsense Invalid traffic

Hi

I had an email from google adsense advising me that there is a high amount of invalid traffic going to my site.

How do I identify this invalid traffic? I have gone through google analytics and I can not find anything?

I have followed guides on how to find bots / invalid traffic but I can not see anything?

My domain was an expired domain, I guess the link building done before has caused this issue??

FYI : There is nect to nothing Direct traffic and refferal traffic hitting my site

Here is a guide that should help.

following, I am interested too.
Where is your traffic is coming from? Search engines, social media?

Block bots, block traffic from countries you dont need, it be easier if you use cloudflare firewall protection.
