Welcome to the Q&A Forum

HI, If you are seeing these warnings in your crawl reports then 410 pages would be a high priority issue since it means you are still linking to these pages from within your own site. In that respect there is no difference between 404s and 410s, they both declare a page is no longer available and if you are still linking to these pages in your site then you should try to find the pages that are linking to them and update the links. If you download your crawl report, open in excel and then filter for 410 errors one of the columns on the far right should tell you which page was linking to the 410 page(s) in question.
