Hello DP! How do you tweak your adsense, if any for the holidays? or in general, how do you tweak your contents/sites? just throwing it out there. -Tim MOD: Please move my post to the AdSense board, as I posted in the wrong category.
You don't need to tweak your adsense ads. Just leave them alone and try to push more traffic onto your sites. You just need more holiday-type content.
Try to get backlinks from highly traffic site or blog and if you have good and interesting content you can got lots of visitors. Another way is improving your ranking for targeted keywords that has high search volume before the holiday starts.
