The protection is world class. The reporting is distinguishable between clients. Their service team is really great, they help very quickly and are always available via their website chat. They even added me to their slack for a deeper issue once!
Missing auto refund requests.
You may want to use in conjunction with Clickease for Bing Ads only, and then you have a complete PPC fraud solution. Maybe Amazon will also allow programmers to do this as well someday?
At the end of the day, PPC Protect is seriously a great product and highly recommended.
Saves quite a lot on larger accounts, hundreds even thousands. Makes client's budgets go further.
