Welcome to the Q&A Forum

One of my e-commerce clients has a script enabled on their category pages that allows more products to automatically be displayed as you scroll down. They use this instead of page 1, 2, and a view all. I'm trying to decide if I want to insist that they change back to the traditional method of multiple pages with a view all button, and then implement rel="next", rel="prev", etc. I think the current auto method is disorienting for the user, but I can't figure out if it's the same for the spiders. Does anyone have any experience with this, or thoughts? Thanks!
