One thought on “Why Do We Need Dofollow and Nofollow Links?

  1. Arti says:

    Google originally created nofollow links in response to blog comment spam. Other search engines, which include Yahoo and Bing, soon followed suit. As blogging grew in popularity, spammers would leave links back to their websites in blog comments. This led to Google creating the nofollow tag in 2005. As a result, these spam sites would gain rank authority on Google, and blog spamming became even more rampant.
