Notice the link at the end of the infographic. Boosting with backlinks is fun. I never used infographics for SEO, but that sure does seem to work for link/keyword juice on these types of sites.
I was all set to give this post props for it's helpful infographic til I too saw the cheezy ad plug. Even worse, it's not "powered by" or "brought to you by"... it's "This infographic was created by". Disappointing. Though this shouldn't impact my judgement of the value or utility of the infographic in imparting information... it just does.
I had the same reaction, and I know Yoast! Seems out of character.
