I have a client who is using google as their internal search tool. I've run their site through two different stats packages and in both cases, internal searches are showing up in the total number of google referrals. In other words, whenever a user searches on the client's site, that search is registering (incorrectly) as a site visit referred by Google.
Has anyone had any experience with this? Is there a way to filter out the internal searches so that I can get an accurate picture of how many visitors are being referred by a search on Google?
