Why doesn't Google tell me all the bad traffic I need to block, to help grow my profits so that I am reliant on their services?

You shouldn't rely on one single stream of data that may have conflicting interests, they may want you to use the service even if it does not align with your website's SEO strategy - It’s best practise to know about bad traffic and sources to begin with, so you understand where that traffic is coming from and block them. Let SEATEXT tell and give high quality insight, so you know what steps you can take to stop this bad traffic from flowing.
