Don’t we all want an answer to the question whether or not social media activity indeed boosts organic search ranking? So far its been a lot of guessing and that will probably continue to be so for a while.
Some have tested things, like for example yesterday Branded3 published the results of an interesting study they did. Another who tried to figure it out was Tasty Placement, who created 6 similary-sized US websites in 6 different cities. They tried to capture the average change in rankings when promoting on different social media channels.
The results you can see in the infographic below. According to them Google+ gave them the most ranking boost, even though the numbers are low.
In my view social does have an effect on ranking, but maybe not always just directly. It can be that people pick up on your content through social and then start linking to you for example. How would you take that in account?
Now this infographic is not an exact measurement, but is simply a starting point. So I’m curious now: what do you think is the impact of social signals on rankings?
