ok, I don't want to brag, (well, maybe I do), but our ratios are really good. Now this may be due to the fact that the program is only a month old and I'm not getting much traffic, but here's an example.
2 weeks ago
Dixie Trailer Trash
only got 3274 unique hits, but we had 33 sign ups. ratio is 1:99
Valerie Exposed only had 420 uniques, but 10 sign ups. ratio 1:42
Now I'm sure once my affiliates start pushing more the ratios may get worse, but right now, the sites are converting.
