Sound familiar (Cough, Old School Panda)? Let's talk more about data refresh. Note: this is how I think quality updates work. Only Google knows the exact process. We know that Google's quality updates should use data collected over time. And when the algorithm update is rolled out, it uses data that Google has collected and processed up to that point (or at some point in the past). So even if Google collects more data

beyond that date, it's not until the algorithm rolls out again and uses the latest data that websites can see the chnges. Again, I can't say 100% that this is how fax number list Google's Quality Updates work, but it does seem to be the case from what I've seen since May 2015. It doesn't doesn't seem to work all the time. Instead, it's a very old-school Panda with the way it unfolds. If the algorithm were real-time, it could constantly use new data to make decisions about URL rankings. But it doesn't seem to (yet) do that.

From what I've seen, a refresh happens every several months; sometimes it's every two or three months, and other times every five or six months. Like Panda of the past, there's no exact timeline, but it's great to see quality updates rolling out every few months. I hope this continues. New factors or just data refresh? Also, since Google doesn't tell us much about its quality updates (or any basic ranking algorithm changes),
