I did it, I asked John Mueller of Google to please give additional advice to SEOs and webmasters about the Google Medic Update, the core algorithm update on August 1st. He said there is "not really" any more advice to give.
I asked John at the 4:28 mark into the video:
I was wondering if this any advice, outside of the advice already given to those who were impacted by the August first ish broad core update. Is anything more you want to tell anybody about that, that hasn't been communicated outside of just keep working on your site and making it better?
John Mueller said:
Not really.So that's something we we've looked at together for a while to see what we can tell people about that but essentially these are algorithmic changes as they can happen any time. And it's not a matter of us saying like the sites of bad suddenly and they need to change but rather things have evolved like things change overall and then that can be reflected in the search results as well.
You can see that Google did spend time thinking about what advice they can give that is new, but they came up with nothing. Or at least that is what John is saying here.
So despite Google saying there is nothing to do - we all have been looking for something to do.
It is important you watch the short clip, I've embedded it to start playing at the start time:
