Baidu Algorithm Update (2013 – 2017)

A few days ago, I felt that, Google and Baidu have changed their attitude towards SEO in recent years. Since Matt Cutts left Google, Google is increasingly secretive about algorithm adjustment. On the contrary, Baidu has announced a number of officially named algorithm adjustments in the past two years, and held communication meetings everywhere, which is a busy scene.

Take a look at Baidu's official algorithm updates. There are a lot of them. The information is scattered all over Baidu's resource platform, concentrated here, so that you can not remember it in the future. In fact, you can't remember it now. Readers can also make a reference. In the future, there will be updates officially named by Baidu, which will be updated on this page.

There are some suspicious algorithm names, such as the so-called Ruili algorithm. I have not seen any official statements, do not know the source, and have not listed them.

From the name of the algorithm, Baidu has shifted from the plant series to the weather forecast series.

Baidu Green Basket Algorithm

Online time: February 19, 2013

Target: buying and selling links, including hyperchain intermediaries, websites that sell links, and websites that buy links.

The green basket algorithm has affected 10W+low-quality sites.

Baidu pomegranate algorithm

Online time: May 17, 2013

Target: a large number of bad advertising pages and low quality content pages that impede users' normal browsing

The pomegranate algorithm is especially targeted at spam advertising pages that pop up a large number of low-quality pop-up ads and confuse the main content of the page.

Green Basket Algorithm 2.0

Online time: July 1, 2013

Target of attack: the external link in the soft message and the site that punishes the soft message.

Baidu Ice Bucket Algorithm 1.0

Online time: August 30, 2014

Target: landing page of mobile terminal that affects user experience.

The main targets of Ice Bucket 1. 0 include the forced pop-up app download, user login, large area advertising and other pages that affect the normal browsing experience of users, especially the sites that must download apps to use normally.

Ice Bucket Algorithm 2.0

Online time: November 18, 2014

Target: full screen download, placing large area advertisements on narrow mobile phone pages to block the main content, forcing users to log in before use, etc.

Ice Bucket Algorithm 3.0

Time of launch: released on July 7, 2016, launched on July 15

Hit object: the behavior of breaking the user's complete search path.

The so-called interruption of a user's complete search path mainly means that when a user visits a mobile page, he or she is forced to open and download the APP of the website before continuing to browse or use it. However, these APPs are not necessarily necessary or commonly used. The simple act of obtaining information is forced to become a complex or costly download act. Baidu Mobile Search will significantly reduce the evaluation of such pages in mobile search.

Baidu Skynet algorithm

Online time: released on August 10, 2016

Target: websites that steal users' privacy.

The theft of user privacy is mainly manifested in the malicious code embedded in the web page, which is used to steal the QQ number and mobile phone number of Internet users. If the website that has been detected and punished has been rectified and meets the standard, the punishment will be lifted.

Ice Bucket Algorithm 4.0

Online time: released on September 19, 2016

Target: mobile pages that have too many advertisements and affect the user experience.

SEO needs to optimize the layout of advertisements on the page, control the proportion of advertisements on each screen, and ensure the user's browsing experience, so as to avoid being hit by the algorithm strategy and affecting the website ranking and traffic.

Ice bucket algorithm 4.5

Online time: released on October 26, 2016

Target: the page that publishes bad inducement advertisements.

The so-called bad induced ads refer to the use of pornographic pictures, explicit text, gambling and other eye-catching forms to induce users to click on illegal advertisements.

As far as I can see, there are still many such pages at present, but few of them can maintain their rankings.

Baidu Blue Sky Algorithm

Online time: released on November 21, 2016

Target: to crack down on the sale of soft articles and catalogues by news sources.

The website that triggered the "blue sky algorithm" problem will be cleaned out of the news source, and its evaluation in Baidu's search system will be reduced.

Baidu Fenghuo Plan

Online time: released on February 23, 2017

Target: Baidu mobile search page hijacking.

The so-called mobile search page hijacking means that when the user returns the search results after browsing such cheating pages, he does not return to the real Baidu search results page, but enters a fake Baidu mobile search results page, which simulates the home page of Baidu search results, but is actually a fake high-risk site, and there are great security risks when the user visits it.

Baidu did not specify how this hijacking was achieved. I guess one possible way is to continuously jump and detect the browser referrer. I mentioned the use of this method in search advertising in the only online SEO training before. I wonder if someone has been inspired by it?

Baidu Hurricane Algorithm

Online time: released on July 4, 2017

Target: websites with bad collection as the main source of content will be severely punished.

Baidu Search has zero tolerance for bad collection, and bad collected pages will be completely removed from the index library, providing more opportunities to display high-quality original content.

Hurricane algorithm will routinely produce penalty data, and will adjust iteration at any time according to the situation. It seems to be offline preprocessed data, which will be centralized online after calculation.

High quality original sites can give feedback in the feedback center if they find that the index volume has decreased significantly and the traffic has declined significantly. Therefore, the algorithm may be misjudged.

At least so far, it is common that the collected and reproduced content ranks better than the original content, and the Hurricane algorithm has not played a full role.

Baidu Spider Upgrade https Grab

Online time: announced on August 30, 2017, and has been online during August

Main impact: The capture of HTTPS data has been upgraded, HTTPS data will be captured by Spider faster.

In addition to crawling, Baidu said that, The weight of https pages also has bonus points. Baidu's original words are "high website evaluation, high landing page evaluation, search and display and other benefits." Google began to raise the right of https pages several years ago.

HTTPS is the trend of the times, mainly for security. Search engines will also give more preferential treatment to https pages in terms of crawling and ranking. It is suggested that the webmaster should transfer the website from http to https as soon as possible. It is better to transfer the website sooner or later.

Baidu Qingfeng Algorithm

Launch time: released on September 14, 2017, and launched at the end of September

Target of attack: It is mentioned that the page title cheats to cheat users to get clicks.

The title cheating mainly refers to the false content of the title (such as the title party, fake official website, fake download page, fake online viewing, etc.), or deliberately piling keywords in the title.

Baidu Lightning Algorithm

Launch time: released on October 19, 2017, and launched in early October

Main impact: The first screen loading time of the mobile page will affect the search ranking

If the first screen of the mobile web page is opened within 2 seconds, it will get a certain weight increase and traffic tilt in the mobile search ranking. If the first screen of the mobile page is loaded very slowly (3 seconds or more), it will be reduced. Between 2 and 3 seconds, no rise, no drop.

As mentioned before, page speed is an important part of mobile SEO.

Improving the speed of page opening involves many things, including but not limited to: server location, bandwidth, performance, database optimization, HTML code, image optimization, compression, reduce the number of requests, CDN, cache usage, etc.

Baidu Thunderbolt Algorithm

Online time: announced on November 20, 2017, and launched at the end of November 2017

Target: The behavior of improving Baidu's ranking through swiping and clicking, that is, the popular Baidu Quick Ranking in recent two years, referred to as Quick Ranking for short.

Excerpted from Baidu's official description of thunderbolt algorithm:

Thunderbolt algorithm will routinely output punishment data to punish the behavior of click traffic cheating. In addition, websites with punishment records will be severely punished, and the serious ones will be banned for a long time.

Since it is ranking, you can give it to competitors. In order to prevent others from framing, Jinglei algorithm will comprehensively consider multi-dimensional features such as website quality and historical data. It is impossible to just look at click data, otherwise it is too easy to frame competitors.

There are two worthy opponents. First, even with preventive measures, is it possible to injure innocent websites by mistake? It should be possible, so the official added a special sentence: if there is abnormal traffic during this period, you can go to the feedback center to complain. Second, from the official tone of Baidu, Jinglei algorithm is retroactive.
