Does Squirrly SEO Offer Any Internal Linking Features?
The My Articles section of the Blogging Assistant (shown below) lets you check the existing content on your site, to help you find if you’ve ever written about the Main Keyword before and add references or internal links.
You can even add snippets of other articles you’ve already written, along with the inner link and reference to your own content.

Also, for Focus Pages, Squirrly checks for Inner Links: checks (using the internal WordPress system) to see if you have built links from other pages on your WP site to that specific focus page.
