This question already has an answer here:
Our website has showing Japanese keywords in Search engine result pages, there are multiple URL's that are appearing on the result page which is not associated with our website
In starting the URL's were up to 1 lakhs, after 15-20 days it went 16k and after that 13k, but again in this week it rises up to 20k which is weird and none of these URL's are in our Website. Can anyone explain or give some solutions regarding this.
We have tried to remove it manually through webmaster but it is not happening.
Also we have put 410 error code but it is also not happening.
