Happened with most of keywords.Was it just 1 keyword? What about your other keywords?
Really annoyingHappened to me to yesterday for two websites. Totally annoying.
Both.Question or statement my friend?
Either way that sucks! :-(
On adult niche some experts mentioned this doesn't impact.Did you try disavowing bad low reputition backlinks?
Even escorts is too competitive.I know the issue as you said this happened to your all keywords than there's nothing to worry about backlinks and there's no update recently. So the simple solution is just to update your content with 10-15% more words of your total words in the post. Nothing to worry it will come back with this in about 2-3 days maybe more.
Keep up, and I don't think "Bangalore escorts" is a pretty competitive keyword.
