Once links to a page have been found, it may be possible to form an objective opinion about the value of that page. The pages that link to the page in question act as an unsolicited list of references which may include indispensable external evidence (for more on evaluating external evidence, see Other Evidence).

Who would you expect to find linking to the page in question if it is a legitimate site? What do you find? Are the "links to" pages trustworthy sites?
What links does the author use and what do these reveal about him/her or the subject matter? Are there any links to outside sources? If not, what does this say about the author? Do all the links work?
