I have an online marketplace platform. Because of adding new products/services, I had to update my links to match the new list. Earlier, Google has indexed most of my pages. Now with the new links architecture, most of the results shown by Google are 404. I submitted new sitemap and the new links are yet to be indexed.
Question: Will 404 pages hinder my websites PageRank? If yes, how to mitigate it? Also, how can I get the new web pages indexed fast?
Please let me know your inputs, as most of my traffic is from Google search, fixing this is very important for us.
