Welcome to the Q&A Forum

Hello We are just now starting up a niche site that will be the new home for a large group of products from an old site. Apart from straight up informative text links, we have set up 301 redirects for the 100 most important products from the old to the new site. Right now, we are in a transition period where we openly tell our visitors that we have a new site for this certain group of products. My question is: for how long should we keep the products on the old site? Can we remove them straight away, since our intentions of the 301 redirects is to preserve the serp positions for the most important products? Does it matter to google if we let the products remain on the old site for a while? Regards
Oskar
