Google started its mobile-first indexing initiative over 5 years and 8 months ago, in November 2016. But we still have sites that are being migrated over from Google desktop-first indexing to mobile-first indexing in 2022.
Yes, last November, Google removed any deadline they had for the mandatory mobile-first indexing switch over. As a reminder in May 201 we reported that mobile first indexing switch was not done yet and then in March we reported that Google was going to migrate over the last batch of sites to mobile first indexing soon. This was after moving the mobile-first indexing deadline from September 2020 to March 2021. Well, Google is still not done moving some sites to mobile-first indexing, even as we pass the second half of 2022.
