Well, today is a holiday in the US, so traffic could take a hit. Its bound to be more like a weekend.
What you are observing is just a part of the profile of the type of people who visit your website. Every site and every business in the world experiences a normal rise and fall of customers within the week, the month, and the year. As you accumulate this data, you will begin to understand when to maximize marketing efforts to either smooth out the cycles or maximize the high points of the cycle without hurting the low. If your site offers content which is seasonal in nature, it may not make sense to waste much money promoting it during the off-cycle periods. That might be a time when you work hard on content and feature improvement. Then, you hit the marketing trail in time to boost traffic during the site's natual peak. The point . . . don't moan about the off-cycle periods, just work on different aspects of your site.
Yep, confirm this Monday was the worst (for the eCPM) in Jan so far... @ clancey Thanks for the advise, it's a good one.
