Who else here has to deal with click fraud?
In April I spent over $200 MORE on advertisements (google adwords) than I did in March and my earnings STILL DROPPED 20%. I'm not talking $10 or $20 less, I'm talking multi-thousands less - yet I paid for 100's more clicks with the SAME keywords I've been using

My highly targetted campaign yielded more visitors, more expenses but LESS results, grrrr
So should I contact google regarding this? Tell them I think I've been a victim of click fraud?
What do you guys do to battle this?
