Does anyone know why clicks for adwords is way more than what both adsense and analytics are showing? According to adwords, I've had 418 clicks, according on analytics I've had only 257, and adsense is showing 212 impressions.
Analytics will not register every click, because people have to have javascript, cookies and images all enabled on their browser for it to work. For my site, about 80-85% of people don't have all three enabled, so that is about how many clicks that analytics is off by. See http://adwords.google.com/support/bin/answer.py?hl=en&answer=55610
