Sometimes you have to lower prices, I don’t mean $5 but whatever minimum you can live with. I did that on 12/3, on 12/4 I got three orders.
Or if you have no sales, increase your prices (on your two most popular gigs) by $10 and see what happens.
My December income varies wildly, but it’s not necessarily my worst month.
There’s a lot of people advertising in December, not to mention people that want ads ready for January. For real estate flippers, winter is a great time to score great deals. Houses tend to sit on the market longer, so sellers are more flexible.
December means a lot of high schoolers will be on vacation, some of them might be young entrepreneurs, seeking professional services.
Some companies close the last two weeks of December, so you might get some trade from their employees.
This is also a great time to create Christmas or Holiday gigs. I’m sure Santa Claus impersonators are making a killing.
