Google prevents click fraud, isn’t it enough?

The short answer is that no, it’s not enough. Google detects very basic click fraud and also, it doesn’t prevent it so it’s not a real protection measure. 
The way it works is by detecting simple suspicious clicks and refunding your account 60 days after you claim it. All the while, your monthly budget continues to be affected. What is more, the attacks are not blocked for good. 

More importantly, since it’s not their priority solution, it is not customizable for the different needs and challenges each industry and company has, rendering it much less efficient than software whose sole purpose and attention is to combat click fraud. 

This is PPC Shield’s bread and butter, our solution was built exclusively to tackle the costly and specific pain of click-fraud.
