There is structural growth and then there is seasonal (cyclical) growth to traffic. Structural growth happens when you are doing things to affect growth e.g. you create a new product, more content, host a giveaway etc. Seasonal growth is the natural ebb and flow of online traffic throughout the year.
Based on analysis of millions of pageviews a year of data for the past couple year I’ve come up with the following high and low season layout. The data pertains to not only personal finance blogs. The traffic differential between low season to high season usually varies between 10%-25% all else being equal. Of course, nothing is always equal with the constant changes in search algorithms, competition, news, and promotional activities.
High Season
January: All those new year’s resolution folks.
March-May: People looking for tax help.
September – November: Catching up with all the things people should have done while on summer vacation.
Low Season
June – August: Summer vacation.
December: Winter vacation, but gearing up towards the new year again.
