On February 7th, Google seems to have rolled out one of the most far reaching updates of the last few years – with the fascinating fact that nobody really knows what exactly Google changed.

This would indicate a granular change at the directory level. If we take a look at the last and the following example we can nicely see how some directories profited from this Google update while the others stayed the same:
The best anyone can do is speculate on which factors play into this update.
