Infographics didn't garner the results we expected from our inbound marketing efforts.
We had much more success with other strategies.
In 2014 my goal is to do more of what worked last year:
Guest posting is not going away, even though Matt Cutts has mentioned it as being a gray area. It never appeals to me when Google authoritatively says they frown upon decades old marketing strategies that didn't have anything to do with spam. Guest posting is more than just link building, it's more about sharing your expertise with someone else's audience. How can that be gray /black hat?
As years go on, I have learnt to ignore what any SEO authority says, and do more of what I feel helps create a great brand.
