Hello If I had an ecommerce site and in the sidebar had random listings, do you think this is a good idea? or should I stick with more permanent links to the product pages, perhaps linking to the 10 best selling or specials? My thinking is that with random listings the pages are already indexed and that each time google recaches the site, the pages linked to from the homepage won't be the same, and that the most important pages won't be always cached from the homepage. What do you guys think?
