Our website promotes a web-based application that's actually on another site (in the ebay.com apps center). When someone hits the "sign up" button on our website, it implements a redirect as it takes that visitor to eBay's apps center to actually sign up for the product. We do that so we can pass information to Google Analytics about the source of those individuals. So i can tell X people from SEM clicked over to the eBay Apps Center and Y people from a banner ad clicked over, etc. Otherwise all source information is stripped out as they go through ebay.com.
The question (finally) - this redirect takes 5 seconds which seems like an eternity. Is there any standard for doing this type of redirect implementation that perhaps we're not doing correctly?
Any help greatly appreciated, Chris
