I am looking at sitemaps of a few large websites like
ebay.com and I noticed that the URLs in the sitemap point to search results rather than the actual product page and I have confirmed that all the URLs are pointing to search results of some keywords.
For example this is a sample URL in the sitemap of
ebay.com, it points to search results of a set of keywords passed in the URL.
Is this a best practice to not to include the actual product pages in the sitemap to reduce the sitemap size? if it is indeed the case then how do the actual product pages get discovered then?
Any guidance understanding this would be greatly apprecitated.
