Ive been running a huge ppc campaign in a niche where the cpc is often $90. About a week ago my site was hit with a 30% CTR all coming from one keyword... The total cost was $2500 in a single day. Whoever was clicking on my ad didn't stop until the daily budget was exhausted. I have never had a ctr over 10% after running this campaign for over a year. Fast forward to today after talking with the adwords team for over a week they determined that a 30 percent ctr on one keyword is not click fraud and i am not entitled to a refund. its such bullshit that they get away with this. Nothing stopped someone from blowing my budget and adwords wouldn't even acknowledge the obvious. I feel like i should just do the same to my competition since adwords doesn't want to acknowledge the click fraud. Has anyone had experience with clickcease or similar products that could protect me? I would love some input.
