January is often the biggest month of the year for education and information products. It is also the best month to promote a business opportunity or self-improvement program.
February is good simply because it is a very slow time for many businesses and advertising is way down. This is a time when you can frequently get great advertising for cents on the dollar.
Remember that while there are theories that for every advertising dollar you spend, you should convert that to turnover. When value opportunities arise to enhance your profile, they should be seriously looked at.
It is a known fact that a lot of advertising translates into sales further down the calender. This is one of the reasons campaigns are measures over a lengthy time frame.
