There is a lot of speculation around the March 2019 core update that started on March 12th that it reversed what the Medic update did on August 1, 2018. While many sites did see gains after dropping from the August 1st update, many did not.

I would not call this a reversal – I would call this an update to the Google core ranking algorithm and thus, with any one who got hit on previously passed core updates, some may see their rankings improve, some may see nothing and some may see it get worse. That is exactly what we have been seeing.

In fact, the survey results (please take our survey over here) now have over 330 responses and I went back to a lot of those that got hit by the Medic Update and asked them if they recovered. Less than 60% said they saw a recovery:

When I asked Google if this was a reversal, they didn’t say it was. They just said “We’re constantly improving our algorithms and build forward to improve.” So yea, they didn’t reverse anything specific, just continued to make improvements to their algorithms.

We even see individual examples from SEOs sharing both successes and failures (not that these are the SEOs managing these specific sites but they have access to their data):

Of course, by now you probably saw the Sistrix blog post that said “What’s interesting here is that many of the affected domains (75% of this sample) were also affected by the big updates of 2018.” I’ll have more data from other providers on that on Search Engine Land this morning – plus more details from Google there in the next couple of hours, I hope.

In short – this was not a simple code revert from Google. Google updates their core search algorithm which has resulted in some sites that were negatively impacted in previous updates to benefit, while others did not.
