One of the main reasons I bought the Yoast SEO plugin was for its internal linking suggestions. It automatically flags similar content that you can link while writing or revising posts. But it didn’t work on my site. Here’s what finally fixed it for me, and might work for you if you find Yoast internal linking not working.
Yoast’s knowledge base has a number of suggestions, including looking for errors, disabling plugins, or switching to a stock theme. If none of those suggestions helps, you might have too many tags.
