Although the updation’s not having large changes but few things have been added to the last paragraph. here we have both version old and the new one let’s compare the changes what exactly has been added or removed?
Old version of “duplicate content webmaster guidelines page”
If you find that another site is duplicating your content by scraping (misappropriating and republishing) it, it’s unlikely that this will negatively impact your site’s ranking in Google search results pages. If you do spot a case that’s particularly frustrating, you are welcome to file a DMCA request to claim ownership of the content and request removal of the other site from Google’s index.
And the new version is
In rare situations, our algorithm may select a URL from an external site that is hosting your content without your permission. If you believe that another site is duplicating your content in violation of copyright law, you may contact the site’s host to request removal. In addition, you can request that Google remove the infringing page from our search results by filing a request under the Digital Millennium Copyright Act.
At this point of time, Google says “We never have an issue with showing your content exactly below down to a site which is copying you content in the search results. Where on the other hand they said that if in case this issue takes place than here is the guideline what to do? Moreover they say that there is only few % of chance for it to take place.
