I believe Systreg is doing ok.
Yeah, in December, January, February and March I got quite a lot of sales and commissions, but nothing at all in April so far, not sure why, still seem to be getting the same amount of visitors, but not getting any sales for some reason
I know my sales could go up considerably if my sites were showing up well on Google, but for whatever reason, none of them are, I checked some of them again today and the best one is the mountainbikeframes site, which is on page 11 of the results, can't even see the others anywhere, although the sites are fully indexed on Google, just not showing in the results pages properly. I have a feeling that Google might be recognising myaffsite store designs as all being the same, like they do with parking pages, hence why they are not ranking well in results.
Not sure what to do, leave the stores up, and hope they pick up now that summer is on it's way and more people are back on their bikes and looking for new ones, or just call it a day and sell the domains, alternatively, try to get them showing up in Google myself by making mini sites on my domains, I don't know.
[edit]
In contrast to Google results, they are well ranked well in Yahoo search:
carbon bikes = result 2 for "carbon bikes" & "carbon bike" (usually both #1)
mountain bike frame = result 1 for "mountain bike frame" & "mountain bike frames"
mountain bike frames = result 7 for "mountain bike frame" & "mountain bike frames"
excercise bike = result 1 if choosing
Show only excercise bike, otherwise page 4
tread mills = result 1 if choosing
Show only tread mills
bike lights = result 15 (has been #1 for months but now dropped down)
bmx bikes = result 6
