Are the other sites being opened in new browser windows or tabs instead of the same window? And are the other customers using the referrer information to track the source of their traffic? That, by itself, will cause the referrer field to be empty for IE visitors, maybe other browsers too. Haven't checked recently because we haven't used referrer for a long time for this purpose. We put marking parameters into the destination URL itself, which is extremely accurate unless somebody decides to list the resulting URL on their site. Also we use "ondown" to add the parameters so that search engine spiders never see the extra arguments, meaning that the search engines will hopefully never list the modified URL.
Web analytics is hard!

Could you please elaborate on that? First time I read this.

It's embarrassing to say this, but I got carried away and was talking about what we do for sites that are not using js tagging. You are exactly right. My ondown suggestion had to do with only server logs!

I don't believe it opens in another window. When someone clicks on a banner it accesses the data base to let them know its gone through and then the visitor is redirected to the site. Yet, the analytics for these sites don't show the incoming redirect.

Another possibility, unlikely from your description, but I'll put it here anyway. Is the traffic flowing from a secure page to an unsecure one? That's another case where the referrer field is empty.

In most cases that I know of, it's going from an unsecure site to another unsecure site.
