Infographics are the most popular visual asset to generate backlinks. If you're not familiar with them, it's a good idea to try them out.
Google basically tells Google that backlinks from websites other than your own site owners are trustworthy sources. This website considers the other site trustworthy. This is especially true if the other website has a high domain authority.
