Hello. Well I have my store ready, I have ads ready. However Christmas is coming up and I feel that it would not be the best time to launch this store right now because the item won't arrive by then. I believe most people are done shopping right now. This would be my first campaign EVER and I hear that cpm is high during this time.
When is the best time to launch? January 1st? Should I launch now.
I'd advise you against launching the store now since even when you do everything right and perfectly perfect - the market is oversaturated with Holiday specials and products right now, with high CPM and CPC - while people are slouching into the holiday season so the demand for most products will slowly drop and pick up again around mid-January.
You can use Google Trends to get a better picture of your product's demand before deciding whether to launch it now or later.
Let me know if my answer is of any help, with a like or thumb up.
