Well it is hard to judge since we are only into July a few days and it is a holiday weekend. I am have a myspace site and yes my traffic and therefore earnings was a lot less over the laste few days. Probably the teenagers who usually are on myspace decided to leave the house blow some fireworks up and party.
I had a low day on the 2nd, since it was Sunday, but other than that, I had one of my highest days ever on the 4th...
My ypn RPC has dropped about 20 cents lower then last month, it is incredible but I am now making slightly more with AdSense then I do with YPN on some sites. But as far as my ypn RPC drop, it has dropped on all my sites and niches that use ypn. I believe it's the 4th holiday effect, and this really is now the summer season, so it might be kinda bad from now until sep. I usualy see a big drop every year from June-Sep, but this year it didn't happen for me in June, it has now that July is here. My best times on the net over the years, as far as traffic and sales has always been from sep-dec, then jan-may it's a little worse, june-aug is the worse for less traffic and sales, but that is again my sites, niches, etc
