Product from an e-commerce that is out of stock and will be restocked soon
The page, of course, must remain on the site, but list of phone numbers in india the unavailability of the product must be communicated to Google in the best possible way, both to deal with the high bounce rate and to improve the overall user experience. For example, you could think of inserting a call to action that invites the user to leave their email to receive a notification when the product is available again, as Zalando does:
Seasonal product, as in the case of fashion products (e.g. swimwear)
The page should be left on the site and re-proposed two or three months before the peak search period. Why? These product listings may have acquired a good ranking and a significant amount of link equity over time. If you do not want to show the page during the off-season, you could consider, in addition to removing it from the menu and sitemap.xml, adding a noindex meta tag . As a result, users would no longer be able to access that link from search results, but only through direct links.
Replacement with a new product line
Again, if the old page is well positioned and generating traffic, you might consider keeping the content and adding a call to action that recommends related content. I happened to use this “trick” with a client who sells beauty products, where I was explicitly asked to also keep the old line, to allow them to run out of stock (below, an example image). But, be careful! The risk of this choice is that you end up creating duplicate content that, if not managed correctly, could be unfavorable for the positioning of the site.
