I guess that update is not fully rollout. If my site gets affected by this, then why not on other keywords. Why vanished my site from google on a particular keyword.

2 Days ago, my website was ranking on Google on 2nd position, on CDAP Digital Advisor, but now it's not, not even on the 10th page of Google. And if I re-arrange the keywords and check with (Digital Advisor CDAP) my ranking is stable. No idea why it is happening on a particular keyword. Already checked with the webmaster and SEMrush for Spam or any issues with the site, but couldn't find anything. Can anyone help me out with that?
