I did have a link from my blog for the firefox web browser via google; over the last 1.5 years this has been clicked on 4,000 times without a conversion - so I haven't earnt a single $. Then a friend rings me and tells me not to spend the dollar he helped me earn; he had finally installed firefox after much pressure from me and he made sure he clicked on the firefox button on my blog - the conversion never showed up on my adsense account. For a living I fix computers; so a week later I was at someone's house and installed firefox on their computer (and made sure I clicked on my blog) - and the conversion never showed up on adsense. So what is going on? Where are my conversions after 2 months?
Well, I always knew AdSense was messed up....... But your actions could get you banned. Try checking the code / re-install it......
I am banned - I write articles about Nigerian letter scams and they threatened to have my account disabled - and they did! Having your account banned and having no conversions is virtually the same thing.
