For people who give time and effort to compose articles and gather information, this is a good play for Google. The copyright those people possess will get them the ranking and the audience that is rightly for them. This has been dogging Google for a long time. It took a step to answering this call for originality and quality. They have received more than 4.3 million URLs for copyright removal notices (made under DMCA) for the last 30 days. That data will be used in their new search rankings. This is good news to copyright advocates like the MPAA and the RIAA but it makes others uneasy. There are challenges to this decision. Some sites may unjustly be put down.
Google cannot decide and determine which webpages have violated the copyright law and which did not. The amounts of removal notices will determine the SEO of the sites and they will only remove pages if they receive a valid copyright removal notice from the owner. That said, pages that will be removed can still be reinstated. Google has “counter-notice” tools that give webmasters the chance to make appeals and have their site be on the SERP again.
