I include most of mine directly in the sentence by highlighting the pertinent phrase, word or sentence and then clicking on the link button and inserting the link directly in the text.
You can also have a link capsule and add them there but I prefer to do them as I go. However HPs (Google) doesn't like some websites so, they may ask you to remove them, they have a word for it . . . let me think . . . oh yeah it's called . . . CENSORSHIP.
You may remember when Google declared that ONLY they were able to discern the truth and any websites or links that didn't fall into their omnipotent paradigm of the truth gets the ax.
So be prepared to delete your links if Google doesn't like them.
