Well, that's my take on it, anyway. Summertime is my worst season, when traffic and income falls to extremely low levels. Over the last two weeks, my sites' income has increased over 3,500%. So, I declare Internet summer to be officially over. If you were waiting for your SEO efforts to produce during the upcoming holiday season, you should start seeing those efforts begin to pay off. On the other hand, if summer is your best season, you'd better start storing nuts for the winter.
