I am bit confuse about the Infographic. What is It and what is the benefit of its Submission ?
This is a question you ask your web search engine of choice.
There is also a forum to ask these types of questions in, easily found from the main forum page.
An infographic (like the one below) is a popular form of content marketing that can help you simplify a complicated subject or turn an otherwise boring subject into a captivating experience. Ideally, an infographic should be visually engaging and contain a subject matter and data that is appealing to your target audience …something that is truly ‘link worthy’ or ‘share worthy’.
In simple terms, an infographic is statistics or other information presented in picture form. Infographics are typically used for marketing or backlinking to a company or site.
