Its presence provides webmasters with a way to tell the search engine to "do not track links on this page" or "do not track this particular link."

The first nofollow just appeared in the page meta tag to tell the search engine that all the outside links on the page should not be tracked. The format is:

Why? such as: You mentioned in the article Chengdu SEO is very good, but also for the link added nofollow attribute requirements Search engine does not track, this is not very contradictory??
