To create a control we randomly

It’s important to note that it’s incredibly rare to expect a leading factor to show up strongly in such an analysis. While the empirical method is accurate, it’s not as simple as predicting the future as a single factor — it assumes that in some cases we’ll know about a factor before Google does. The underlying assumption is that in some cases we’ve seen a ranking factor (such as an increase in links or social shares) before Google bots do, and that over a 2-week period, Google will catch and correct the misranked results. As you might expect, this is a rare occurrence, as Google crawls the web faster than anyone else. However, with a sufficient number of observations, we should be able to see statistically significant differences between lagging and leading results. However, the method only detects when a factor is leading and Moz Link Explorer has discovered the relevant factor before Google .


Control:
selected pairs of adjacent URLs in the first SERP uruguay number data and determined the probability that the second would outperform the first in the final SERP collection. About 18.93% of the time, a poorly ranked URL would outperform a better ranked URL. By setting up this control, we can determine whether any of the possible correlations are significant factors - that is, they are likely causes of better rankings because they are better predictors of future changes than random selection.

Facebook Shares:
Facebook shares performed the worst of the three variables tested. Facebook shares actually performed worse than random (18.31% vs. 18.93%), meaning that randomly selected pairs would switch more than those where the other had higher shares. This is not entirely surprising as it is the general industry consensus that social signals are lagging factors – that is to say that traffic from high rankings drives high social shares, not social shares driving high rankings. Then, we would expect to see a change in rankings before we see an increase in social shares.
