In an effort to improve performance of my website and to give users a better experience I decided to use CloudFlare. It was supposed to make my website load faster.
Big surprise this morning when I checked yesterday's stats:
1. According to Google Analytics my site speed didn't improve!
2. According to my Adsense account there was $*** invalid traffic. More than 50% of my Adsense income vanished because Google thinks it was invalid traffic.
Conclusion: do not use CouldFlare. It is doing something that upsets Adsense.
