During the hangout on 10/1/2021, one webmaster asked John Mueller whether or not their site had been hit by the June spam update.
The webmaster’s situation is that they had reverted a few sites back to their prior format. Then they did a redesign. After the redesign, the site has dropped in rankings and performance.
John explained that he would not expect the spam update to target sites that were hit after doing a redesign.
He expects the spam update to really go after very bad spammy content or really bad spammy links.
Even keyword stuffing is not the type of spam that would have been targeted by that spam update.
To John, it sounded like perhaps the site is set up in such a way that Google is unable to process the pages as it was able to before.
John also mentioned that the algorithm runs into lots of sites that offer illegal movie downloads, and as a result of that, perhaps the algorithm is seeing the client’s site as a potential site in that vein, which is why they dropped in performance.
The conversation starts at the 24:55 mark in the video.
