An infographic is a visual representation of some type of data or information, presented in an easy to understand graphical style. Infographics are often used in SEO link building by allowing other webmasters to place the infographic on their website, along with a link back to the site who originally published it. Like many SEO and website promotion tactics, this has become somewhat abused and can be considered spam if the infographics are not really useful. A well designed, useful infographic can still be helpful in gaining incoming links to a website.
