On our company site we have pages for multiple products. Some of the products become "deprecated". These products are of no interest for us because they give no income.
Pages for "deprecated" products attract relatively high number of visitors (more than the half combined). Keywords for "deprecated" and "not-deprecated" products have very-very little in common.
Is it wise (from SEO perspective) to move all the pages for "deprecated" products to other sites?
For us it basically doesn't matter what will happen with "deprecated" products and pages related to them but we of course don't want to affect other products in any negative way.
The whole point of all this is to "tell" search engines that our site is more focused on what will left.
