Well, Facebook is one of the most popular ways for advertising today and lots of companies use it.  It’s clear that ads with social medias helps to reach absolutely different results and in some occasions it’s more efficient than any other. Ads is an important part of business and making money, that’s why it’s  important to know how to get the most. I also use Facebook for ads and for me it was very interesting to know if I can get any better results.  I know some people who put ads on the first place and use pay day advance to pay for it. As for the infographic, I think it's a string tool because it allows your consumers to see everything in pictures.
