Infographic: 40 pervasive SEO blunders

Google, which wields immense power in determining how businesses rank online, is notoriously secretive about the inner workings of its algorithms. They don’t fully reveal the rules of the game, and, as anyone who follows SEO knows, Google’s guidelines are quite fluid.

There are, however, certain rules that don’t change. MarketingProfs posted an infographic that lists 40 common SEO mistakes, along with descriptions of how bad each bugaboo is for your website. The graphic, originally created by SEMRush, features data pulled from audits of 100,000 websites and 450 million webpages.
