I have a client (ad agency) that runs quite a few Adwords campaigns for clients and has asked me to recommend click fraud tracking software. I run only a few small campaigns and have no experience with any of this.
Could you let me know what software you use and what you like or don't like about it, please?
Google has some built in Click Fraud detection already, but I hate to say it if your buying PPC in certain markets/niches you are probably going to have to live with some level of click fraud.
