At the Brighton SEO conference, Gary Illyes from Google said that the third party SEO or search ranking algorithm monitoring tools tend to get the weather right most of the time. Here are some tweets covering what he said at the event:

This is all very interesting to me because Google has somewhat been fighting against these tools for some time. Google said in the past that these tools pick up on the wrong signals, has hinted Google messes with the tools and even suggested they were scrapers that were against Google’s terms of service.

But now, it seems at least Gary Illyes of Google is changing his tune.

Gary did add on Twitter that “we see low impact updates freak out MozCast, sometimes it doesn’t notice a bigger change.”

In any event, here is the latest on that controversial topic of rank checking and algorithm monitoring.
