SEO Auto Linker is an update to the much loved <a href="https://wordpress.org/extend/plugins/seo-automatic-links/" title="SEO Smart Links" rel="ugc">SEO Smart Links</a> plugin.
The plugin automatically links words and phrases in your post, page or custom post type content.
The difference is that you no longer have to try and guess what links will appear. Specify keywords in a comma separated list, type in the URL to which those keywords will link, specify how many links to the specified URL per post, and then specify the post type. SEO Auto Linker does the rest.

I just recommended this to Paul Boag of the Boagworld podcast. It's that good that after 4 years since last update it's still working with a WordPress 4.8 I tested it on!

Very robust bit of kit

SEO Auto Linker allows you to automagically add links into your content. Great for internal linking!
