Too Long; Didn't Read
Link spamming is the practice of publishing or embedding links without consideration of the context of the post, the value of the link or the website, or accepted link-building techniques. Spammy links add nothing to the sites they are on, thus they have no meaningful impact on how well-written your website is, as determined by both users and search engine algorithms. Google, Yahoo, or Bing (the top three search engines) may deindex your site's content or impose a rank penalty on it.
