Why do we need internal links?
– They may help your new page get indexed faster.
– They will transfer PageRank to the new page, which may help it rank higher in the search results.
To find pages with few internal links, go to the Links report in Search Console. Click “More” under the “Top linked pages” report under the “Internal links” subheader.
Sort the list by “Internal links” to see “forgotten” pages.
If you find pages with few internal links that are worth keeping, then it would make sense to either:
– Add more relevant internal links to them;
– Update the content and add more internal links where appropriate.
