Algorithm là gì? Google Update là gì? Tất cả những lần Update của Thuật Toán Google

Algorithm là gì? Thuật toán Google là gì?

Algorithm là gì? Đây là tên viết tắt của Google Algorithm (Thuật toán Google): Một hệ thống phức tạp được sử dụng để truy xuất dữ liệu từ chỉ mục tìm kiếm và ngay lập tức cung cấp những kết quả phù hợp nhất cho một truy vấn. Công cụ tìm kiếm này sử dụng một sự kết hợp của các thuật toán và nhiều yếu tố xếp hạng khác nhau để cung cấp các trang web được xếp hạng theo mức độ liên quan trên các trang kết quả tìm kiếm của nó (SERP).

Trong những năm đầu, Google chỉ thực hiện một số cập nhật nhỏ cho các thuật toán của mình. Nhưng hiện nay, Google thực hiện hàng nghìn thay đổi hàng năm.

Các cập nhật này đa số là những thay đổi nhỏ đến mức hoàn toàn không được nhận thấy. Tuy nhiên, đôi khi, công cụ tìm kiếm triển khai các cập nhật thuật toán lớn có tác động đáng kể đến SERP (Search Engine Results Page, trang hiển thị kết quả tìm kiếm).

Đây là bản danh sách những lần Thuật Toán được Google Update (và được coi là bản cập nhật quan trọng) được sắp xếp theo các năm:

Năm 2003

16/11/2003

• Florida Update (Google Florida): Đây là bản cập nhật đánh dấu một kỷ nguyên mới của SEO. Các website (bao gồm các nhà bán lẻ sống dựa vào affliates để tăng traffic) sử dụng các thủ thuật spam từ các thập kỷ trước (ví dụ như nhồi từ khoá – keyword stuffing, sử dụng nhiều website chung thương hiệu, làm chữ vô hình – invisible text và link ẩn – hidden links) để đạt xếp hạng cao cho những từ khoá HOT về thương mại (high-commercial keywords) đã chứng kiến thứ hạng của họ bị xoá sạch ngay trước mùa mua sắm cuối năm.

Năm 2005

01/09/2015

• Jagger Update: Đây là bản cập nhật được chia làm 3 giai đoạn (Jagger 1, Jagger 2 và Jagger 3), tập trung vào backlinks, bao gồm: Xây dựng link một cách không tự nhiên, mua backlinks và các dạng Spam khác.

15/12/2005

• Big Daddy Update: Big Daddy (or Bigdaddy) was a gradual update to Google’s infrastructure that began rolling out in December 2005 and was completed in March 2006. This update changed how Google handled technical issues such as URL canonicalization and redirects. Some websites didn’t make it into the new Big Daddy data centers, typically due to unnatural linking (e.g., excessive reciprocal linking, linking to spammy neighborhoods, paid links). (Xem chi tiết)

Năm 2009

18/01/2009

• Vince Update: Google’s Vince update was a quick, noticeable change in broad-level, competitive keyword terms to favor first page rankings for big brand domains vs. previously ranking sites (typically less authoritative sites, affiliate sites, and sites that had won this coveted visibility purely through SEO efforts).

10/08/2009

• Caffeine Update: Google’s Caffeine update was a new web indexing system that allowed Google to crawl and store data more efficiently, resulting in 50 percent fresher results. Developers were given early access starting in August 2009 before the update officially rolled out June 8, 2010.

Năm 2010

28/04/2010

• Penguin Update: A long-anticipated “over-optimization” penalty finally arrived on this day. Google announced the launch of a (then unnamed) algorithm change meant to downrank websites engaging in aggressive webspam (e.g., keyword stuffing, unnatural linking) that violated Google’s Webmaster Guidelines. Google said this update would impact 3.1 percent of English queries. Just two days later, we learned the name of the algorithm: Penguin.

27/04/2012

26/05/2012

Other websites that hadn’t been caught by Penguin the first time around took a hit.

08/06/2012

• Panda update 3.7 (#15): Google confirmed a refresh of the Panda algorithm started rolling out on this date, impacting less than 1 percent of U.S. queries and ~1 percent of worldwide queries. Ranking tools suggested it was bigger than more recent Panda updates.

14/03/2013

• Panda Update (#25): This update was not confirmed by Google though tools suggest it occurred on roughly this day.  Google’s Matt Cutts seemed to suggest that this would be the final update before Panda would be incorporated directly into the core Google algorithm. Instead, however, Panda data refreshes started rolling out monthly over a 10-day period, without any further confirmation from Google.

22/05/2013

• Penguin Update 2.0: This was a “next generation” of the Penguin algorithm, as Google’s Matt Cutts explained in a blog post. This version looked deeper than the website homepage and top-level category pages for evidence of link spam being directed to the website. Penguin 2.0 impacted around 2.3 percent of English queries.

11/06/2013

• Payday Loan Update: Google Payday Loans algorithm update targeted spammy queries mostly associated with shady industries (including super high interest loans and payday loans, porn, casinos, debt consolidation, and pharmaceuticals). It took about 1-2 months to fully rollout and impacted about 0.3 percent of U.S. queries.

26/09/2013

• Hummingbird Update: The Hummingbird update was a major overhaul to Google’s core search technology. Google needed a way to better understand and return the most relevant results to more complex queries as a result of the growth of conversational search (i.e., voice search). Google said the new algorithm affected about 90 percent of searches worldwide. Although this update was announced on this date, it actually started rolling out in August 2013.

Năm 2014

24/07/2014

23/09/2014

• Panda Update 4.1 (#27): Google’s Pierre Far announced that this update to the Panda algorithm added “a few more signals to help Panda identify low-quality content more precisely.” It impacted 3 to 5 percent of queries.

17/10/2014

• Penguin Update 3.0: Though named like a major update, this was actually another data refresh of Google’s Penguin algorithm. Penguin 3.0 allowed those impacted by previous updates to emerge and recover, while many others who had continued to utilize spammy link practices, and had escaped the radar of the previous updates, saw an impact. The update took about three days to fully rollout and impacted less than 1 percent of English search queries.

Năm 2015

21/04/2015

• Mobile-Friendly Update: The Mobile-Friendly Update (or “Mobilegeddon”) was an update meant to reward mobile-friendly websites with better search rankings and provide better results to searchers on mobile devices. This update impacted all languages globally

03/05/2015

• Quality Update: The Quality Update (or the Phantom Update) was a confirmed change to Google’s core ranking algorithm – specifically, how Google assesses quality signals. Websites with content quality issues, as well as too many ads, seemed to be impacted the most by this update.

17/07/2015

• Panda Update 4.2 (#28): Google announced a Panda refresh that would take months to roll out and impact 2 to 3 percent of English queries. Due to the slow nature of the rollout, it’s unclear how substantial the impact was or precisely when it occurred. It was the final confirmed Panda update.

26/10/2015

• RankBrain: Though it had been in testing since April 2015, Google officially introduced RankBrain on this date. RankBrain is a machine learning algorithm that filters search results to help give users a best answer to their query. Initially, RankBrain was used for about 15 percent of queries (mainly new queries Google had never seen before), but now it is involved in almost every query entered into Google. RankBrain has been called the third most important ranking signal.

Năm 2016

16/01/2016

• Panda Core Algorithm Incorporation: Google confirmed that Panda had been incorporated into the core Google algorithm, evidently as part of the slow Panda 4.2 rollout. In other words, Panda was no longer a filter applied to the Google algorithm after it does its work, but is incorporated as another of its core ranking signals. It has been clarified, however, that this doesn’t mean the Panda classifier acts in real time.

12/05/2016

• Mobile-Friendly Update (#2): The second Mobile-Friendly Update (or “Mobilegeddon 2”) was an update to Google’s first mobile-friendly update, meant to “increases the effect of the ranking signal.”

01/06/2016

• Quality Update: Though unconfirmed by Google, data indicates that another content-related Quality Update to Google’s algorithm began rolling out around June 1, with additional search ranking volatility seen on June 8, 21, and 26.

23/09/2016

• Penguin Update 4.0 & Core Algorithm Integration: The final update to the Penguin algorithm saw it integrated into Google’s core algorithm, meaning Penguin was now evaluating websites and links in real-time. Another big change was Penguin devalued links, rather than downgrading the rankings of pages.

10/11/2016

• Unnamed Update: Search industry chatter and data from SEO tracking tools indicated some sort of unconfirmed Google update happened on November 10.

Năm 2017

10/01/2017

• Intrusive Interstitials Update: On August 23, 2016, Google announced an upcoming change that would target intrusive interstitials and pop-ups that hurt the search experience on mobile devices. As promised, this update rolled out January 10, 2017. The impact of this update on rankings was minimal.

01/02/2017

• February 1 Update: This was a minor and unconfirmed Google update. Although all information about this update is more speculation than fact, it seemed to target private blog networks or those doing spammy link building.

07/02/2017

• February 7 Update: This unconfirmed major update resulted in massive rankings shifts in Google’s SERPs, which also meant major increases or decreases for some websites. Overall, it seems higher-quality and more relevant websites gained the most visibility.

07/03/2017

• Fred: Google’s Gary Illyes jokingly referred to this update as “Fred” and the name ended up sticking. But this algorithm was no laughing matter for those impacted. This major algorithm update seemed to mainly target low-value content. On March 24, Illyes officially confirmed the update. But Google has refused to share any more specifics, instead choosing to say that all the answers about Fred can be found in Google’s Webmaster Quality Guidelines.

17/05/2017

• Quality Update: Starting May 17 and lasting for about a week, SEO tracking tools reported lots of SERP volatility. While the impact seems limited, those sites impacted by this update tended to have issues with aggressive/deceptive advertising, UX issues, and thin/low-quality content.

25/06/2017

• June 25 Update: Various SEO tracking tools detected a significant, though unconfirmed, Google update on this date. One analysis found that this update caused the biggest fluctuations for pages ranking in Positions 6-10. While it impacted most niches, the good and beverage industry was reportedly impacted the most.

09/07/2017

• Quality Update: SEO ranking tools detected some minor volatility on July 9, potentially another (unconfirmed) Google quality update.

19/08/2017

• Quality Update: Webmasters and SEO ranking tools detected some minor volatility on August 19-20, with signs indicating this may have been another (unconfirmed) Google quality update. Among the ranking casualties: category pages, pages with aggressive advertising, lower-quality/thin content, and other negative user experience elements, according to an analysis by Glenn Gabe, president of GSQi. There was some speculation that Google began testing this algorithm on August 14 because pages that were impacted (either positively or negatively) on this date were further impacted on August 19.

08/09/2017

• Fall Flux: Industry chatter and SEO tracking tools indicated some sort of (still unconfirmed) Google update may have occurred on this date. Glenn Gabe, president of G-Squared Interactive, also detected several noteworthy Google changes impacting traffic and search visibility starting September 8. This was followed by additional volatility and fluctuations on September 18, 25, and 29, as well as October 4, 8, and 12.

12/12/2017

• Maccabees Update: Some in the search community reported their websites being hit by update between December 12 and 14. Google confirmed several minor changes to the core algorithm during the timeframe, but downplayed the significance of the period of flux.

• Broad Core Algorithm Update: On March 12, Google confirmed via Twitter that a “broad core algorithm update” had rolled out the prior week. While Google was light on details, Google said the changes were meant to “benefit pages that were previously under-rewarded,” and advised everyone to “continue building great content.”

27/09/2018

• A “Small” Update: On September 27 (Google’s 20th birthday), many within the SEO community began noticing significant spikes and drops in traffic, indicating some sort of update was underway. Some of the sites impacted by the August broad core algorithm update reportedly made a recovery. Google’s Search Liaison Danny Sullivan confirmed via Twitter September 29 that some sort of “smaller” update had taken place (but it wasn’t a broad core algorithm update).

31/10/2018

• Unconfirmed Halloween Update: Some webmasters reported changes starting around Halloween, perhaps indicating an (unconfirmed) Google update. But there was little evidence of a significant update here.

02/06/2019

08/04/2021

• Product Reviews Update: This new search ranking algorithm update was designed to reward “product reviews that share in-depth research, rather than thin content that simply summarizes a bunch of products.” In their announcement, Google also shared nine useful questions to consider when creating and publishing product reviews.

• Broad Core Algorithm Update: Google Search Liaison Danny Sullivan announced via Twitter that a broad core algorithm update was about to be released.
