Myth: One effective way to improve my blog’s SERP rank is to purchase or exchange links (sometimes known as “backlinks”) with as many bloggers as possible, so that there’s a lot of traffic going to my blog.
Fact: If you blog about sailboats, the more sailboat-focused sites and articles that organically link to your blog as a fantastic source of sailboat info, the better. On the other hand, Google won’t be impressed if it sees a ton of links to your sailboat blog from blogs about, say, marketing, basketry, lipstick, electronics, or SEO tactics.

The more tactics bloggers come up with to fool Google into ranking their sites higher than they deserve to be, the more Google corrects its search algorithms to screen out such bad behavior.
Paying for backlinks is a case in point: in April 2012, Google introduced its controversial Penguin algorithm that improved screening for this bad practice, and many bloggers with excessive backlinks found that their SERP rank plummeted.
