Long-tail anchors are similar to partial anchors, but they contain more words. These give you a chance to include your keyword along with some related, descriptive, generic, or branded keywords. 

Sometimes, long-tail anchors can include an entire subheading or headline for a link. Other times, writers will link to a whole sentence. While you don’t necessarily want to write long-tail anchors all the time, they can be useful for SEO. Plus, you can’t control what other sites do.
