Hello friends, I am a publisher of Adsense since 11 months, recently i observed invalid click activity on my ads and i strongly believe that my competitors are clicking on my ads. My CTR is more than 8 % these days which generally lies between 1-3%. I am having a good website with good earnings. I informed google about this activity by filling the form (reported for invalid click activity on my account). But no improvement found yet. They are clicking on my ads daily and since 7 days, there are regularly make huge of invalid clicks. What are the options for me? and also I also want to know that if there is a way to ban an area from visiting my website. I want to ban the whole city from visiting my website. Is there any way?
Reduce the number of ads on your blog for couple of days. I also had the same problem, so i decided to put a single advertisement on whole website on a page which was very less visited. Then in just 3 days everything got normal. Most people don't know about advertisements looks but when they see media rich ads they easily recognize them, but in textual ads very less people recognize this as advertisement.
Like imuj already said, remove your ads - this should have been the first thing you did... wait a few days and put them back and watch your %% closely..
Those people want to put you out of business but it wise to play a fool and withdraw some adds for a while and resubmit them after some few days
