Google has thoroughly evaluated each of these requests, and once they deem it valid, the content in question, especially the ones that violated the copyright act guidelines were taken down. To further Google’s continuous effort in taking down new online piracy or copyright violators, they officially updated and refined their Pirate signal in 2014. In addition, Google has also introduced a new ad format where they show legitimate content results to users looking to download free content. Jumping forward to February 2022, Search Engine Land wrote about Google releasing a document to the US Copyright Office.
The document states that Google has developed a demotion signal for its search engine where it causes sites to appear and rank much lower in search results. The document also states that “when a site gets demoted (by Pirate signal), the traffic Google search CY Lists sends it drops, on average, by 89% on average.” You can read more about the document shared by Torrentfreak here. Hummingbird Hummingbird was not just a simple core update. In fact, this was a complete overhaul of Google’s algorithm since 2001. Matt Cutts explained that Hummingbird was a rewrite and not just a part of the core algorithm.

What Cutts essentially means is that Hummingbird does “a better job of matching the users’ queries with documents, especially for natural language queries, you know the queries get longer, they have more words in them and sometimes those words matter and sometimes they don’t.” This move from Google intends to refine its search results as users began utilizing voice search. What Google actually noticed is that users who do voice searches on mobile devices ask long conversational search queries. With the old algorithm, Google would match a user’s typed search query with a webpage containing every word in that query. But with Hummingbird, means instead of just matching keywords with pages. Hummingbird uses semantic search to do the heavy lifting in creating and understanding its user query intent.
