This question already has an answer here:
Our website was copied 100% and duplicated in a different domain
Another website is reflected and located above my site in the search results
What part of your content should be copied before you can file a DMCA complaint?
I have noticed a big change in my SERP over the months and I have come to know that few sites have copied my content. How should I claim this from Google?
Is there any general criteria for this?
There are Google provisions that I understand. But are your policies clear about this?
