How much does Xmas season affect your earnings?

Have a mature amazon affiliate site but two new ones which I started at the beginning of this year.

I'm seeing big increases in daily commissions and traffic. But my SERPs are also increasing so it's difficult to pin down how much of this is down to the xmas season.

Those already earning through Amazon Associates, how much more do you find yourselves making during late October/Nov/Dec vs other months? 2x? 3x?

Usually 2x. I'm in the UK so with the dark evenings and poor weather people are sat in front of their computers/devices browsing. I use that to my advantage though and get a few topical posts up and running that are focused on who is browsing, what times and what they may be interested in

For me, it's the same. Cause I don't make much money.

People usually making something like up to even 5th amount of what they need to considering all that anyway. That way we can go on doing something we really do with whatever you want really. You need just to test it for yourself anyway and take care of the rest.
