As we had expected and already pre-announced in our coaching group, Google rolled out a CORE update in May 2020:
The May 2020 Core Update is now rolling out live. As is typical with these updates, it will typically take about one to two weeks to fully roll out.— Google SearchLiaison (@searchliaison) May 4, 2020
Right now, it's probably early to make any assumptions - as Google states, it's going to take up to 2 weeks for the update to come through, but we can definitely see its impact on a variety of sites right now already.
Our R+D department is working like crazy analyzing impacts, possible recovery strategies, so make sure you come back to this post once in a while and check for updates!
