Google burned me good with AdSense. I had been running their contextual text links on a half dozen of my sites.. after I had earned about $400, they sent me an "invalid clicks" email which looked like it wasn't even written by a human. I had no idea what they were talking about, and I promptly asked what was up, and nicely offered to fix the problem..
They ignored my responses and I never did see the money.
I would suggest that folks avoid AdSense like the plague. I searched around about this "invalid clicks" issue, and it seems to happen to a lot of people, and it always seems to happen when it's getting close to payout time. Maybe this is part of a plan to increase their margins?
I've since swapped out all my CPC Google AdSense ads with CPA ads from AzoogleAds. I'm making WAY more money with them, and the checks show up on time every month when they're supposed to. No lame excuses or reps hiding under their desks.
I have earned over $200,000 USD lifetime with them, and I've been paid on time every time. I would strongly suggest that folks check them out, and stop running Google AdSense ads on your sites before you get burned too. It seems to be standard protocol. It's quite unpleasant to drive in thousands of legitimate clicks over the course of a few months for an advertiser, and then get screwed by them when it comes time for them to square up.
I'd also like to mention that I'm NOT an employee of AzoogleAds, nor am I trying to just spam their name out. I have had great personal experiences with them, and I think they're a rock solid Internet marketing agency.
...and they've never burned me like Google AdSense did.. even on 5 figure checks.
Two Thumbs Up!
