My first winter
 

I really don't know what to expect, are sales supposed to increase or decrease over the winter?

They should shoot up in early January and hopefully stay strong through at least April if not May. That's been my experience anyway.

so that means that they go down as the summer approaches?

If you are good they never decline but yeah more people are surfing because it's so cold outside usually...

no, they dont.

so far I haven't noticed any changes, I'm hoping things stay as they are or increase

There are so many variables. Alot of webmasters' sales slow in the summer and around Christmas, but others remain strong throughout the year. Maybe it has to do with the type of websites you have combined with the type of traffic you get?

What does that mean exactly?

if you have bad traffic, why would that mean better sales because of a season?

Honestly I don't know. I've heard alot of ideas as to why. Maybe someone who knows more will post.
