As a sponsor, I can tell you there will always be severe ups and downs...
I've seen it in my own program...webmasters sending 5 signups a day for a few days, then POOF, nothing for a month, then BAM right back...all with pretty close to the same amount of traffic...
If you constantly get your traffic from the same sources, you should always change your sponsors out every couple weeks, keep rotating in and out...If all your traffic comes from the Hun, check and see what sponsors the upper links are using...that can have an effect on your stats as well...
as for ARS, we've had great success using them on our exit consoles...2-3 consoles deep and we were seeing 1:900-1:1200 and that's EXIT traffic...if that's shaving, then whip out the razor blades...
We've rotated out sponsors always keeping our stuff fresh, but ARS almost always outperfrms the others...the only one I've seen convert better is Nakkidnerds.com (no we don't own the site, but we make a hell of a lot of money with them...sure would like to buy that site...if anyone knows the gal who runs it and can put in a good word for me, let me know...LOL ;)))
So, Marc, keep up the good work
