I’d have to say that internet marketing is quite seasonal. It’s so seasonal, in fact, that next summer I plan on taking some time off to coincide with the lower traffic I’ll be expecting. There is almost no comparison between the traffic levels of June and October. The Fall sees a giant increase in traffic, compared to the summer months which are way down.
Knowing how vastly different the traffic levels are should help when it comes to making your schedule. If your traffic hits a low point in June, then that really is the month you have to consider taking a vacation during.
The flip side of this coin is that you can always consider getting your traffic up in the summer time, even if it is a slow period. Just because the overall traffic is slow doesn’t mean you can’t double your traffic from year to year. If you do, you’ll barely notice the seasonality.
