Google Panda algorithm two anniversary festival-to Baidu Green Luo

February 24, 2011, Google released the "panda algorithm", the algorithm upgrades the entire SEO industry as a shock. And this algorithm is still in the upgrade optimization, is now known as the "Penguin algorithm."

February 19, 2013, Baidu released to date the most widely affected by the "Green Luo algorithm", the same in the domestic SEO circle has produced a great impact. Subsequent effects continue to be observed.

　　

The panda algorithm's first name is "farm", mainly for "content farm" sites that use a lot of low-quality content to get a better ranking. Later, according to the algorithm group, the name of a member changed to a panda. Unlike Baidu, Google, at the beginning of the calculation, did not explicitly identify the site it was targeting. "I think you will have an idea of the types of sites affected by the algorithm," said Matt, the head of Google's trash, who was just vague on his blog. ”。 Indeed, some SEO research companies, by contrast, quickly discovered that the algorithm was clearly pointing.

Search Engine Optimization competition, the same is the elimination of the other long. There are sites affected by the drop in rankings, which also means that there are sites that benefit from getting better rankings. After two years, the famous SEO site search Engine Land (hereinafter referred to as the SEL) and other SEO companies jointly on the impact of the site at that time a review. In the list of more than 20 sites, most of the sites still did not respond to the original rankings, which fully responded to only two.

Historical review:

Searchmetrics (SM) and Sistrix two search engine service companies have made a corresponding website data analysis for Panda algorithm, listed some of the most affected sites. Many of them are familiar websites of Chinese webmaster, such as Ezinearticles,hubpages,squidoo and other articles writing station. Of course, there are demand media stations, such as Ehow, which are most widely affected.

It is also from the data analysis of the two companies, so many domestic webmaster learned that many have not previously paid attention to but in foreign webmaster and SEO circle very famous site. Two years later, what about the SEO performance of these sites on Google?

Current situation Analysis:

We can only use the "dead" four words to describe the scenery of those unlimited content farm site.

The SEL contacted SM in the hope that the other side will make an analysis of the site that was affected two years ago. SM selected 22 sites for comparison, giving the following table:

　　

Note: the "SEO Visibility" parameter in the table is based on the score after the search of millions of keywords

First of all, the author himself to this form of intuitive trust. Table listed in the Tradekey, once in the foreign trade business-to-business market Scenery Unlimited, and in Google's ranking ferocious and famous. But now Tradekey seems to have completely disappeared from Google, that year's ranking advantage has been replaced by Alibaba, I believe many foreign trade friends have a deep feeling about it. Therefore, I think the table can be very valuable reference value, basically can reflect the impact of the panda algorithm before and after the situation.

From the above table we found that the 22 sites after two years of rectification, the status quo is still not ideal. Comparing the H and I columns, we found that only the two sites MerchantCircle and business recovered after the impact. But also only a recovery, compared to the panda before the score gap is still very large, can only talk about the comfort of the table. The rest of the sites were worse off than they were the first to be affected. EzineArticles in the panda algorithm, after the introduction of a series of articles included in the policy, but also issued a corresponding commentary video, but now it seems that the effect does not seem ideal.

About Demand Media

Let's say demand Media again. Panda algorithm released after the DM station group overnight for the world known, a content farm in the form of a huge flow from Google and the listing, is definitely a miracle. At that time, many people are also discussing the DM under the influence of the panda suffered losses. However, it is surprising that at the beginning of the February 2011 Panda release, DM's main site ehow by Google's pro-Lai, the flow will not rise. However, April Google released the panda 2.0,ehow with the fall. The following are two contrasting charts published by SM and Sistrix at the time, similar to the basics:

　　

　　

From the above two tables we can see that ehow between February and April of the ice fire. The same DM another very famous site Livestrong also experienced the same suffering, although the time gap is a bit big. The following figure is a chart published by SM:

On the surface, the panda algorithm has a very big impact on DM. A year ago, the Los Angeles Times reported that DM lost 6.4 million dollars in its fourth-quarter earnings in 2011, affected by Google. But that does not seem to be the case. DM before the release of the financial statement said: 2012 DM's website PV (page views) than in 2011 up 24%. Perhaps as the CEO said: DM is and will continue to improve the quality of the site content.

In short, DM for the panda, seems to be an unresolved problem!

Green Luo algorithm

February 19, 2013, Baidu released a green Luo, designed to combat the chain of intermediaries, selling links, purchase links and other hyperlinks cheat. For this upgrade, must be admitted to the SEO is an important measure of fairness, although there are copycat behavior (described later). Because there is no such a specific SM such as the search engine data analysis company to do some detailed comparisons, but from some webmaster and SEO forum, you can understand that the impact of this upgrade is quite extensive.

As for why the above mentioned follow the bandwagon, because this involves a possible recovery method.

The article began with the Google algorithm to upgrade to today has been renamed as Penguins, and the most serious penguin impact is the chain behavior. After the Penguin, Google released the chain to delete the tool link disavow, similarly, Baidu recently released a rejection of the Chain tool beta test Bulletin. Here, according to personal experience and a lot of foreign research on penguin Algorithms and Solutions, by the Green Luo algorithm impact of the site can be restored.

Recovery scenarios

The author has a total of two sites, one is the company's foreign trade English site, in the panda survived, but under the Penguin gun, has been restored. Another is the search net (www.sowu.com) for the purchase of the chain to accept the effect of green Luo, has been restored. Because the years at home can not surf the internet, after coming back to study the specific situation, according to Google and Baidu algorithm contrast, the following is a list of some of the recovery plans and future arrangements. The theoretical guidance of the recovery plan visible article: Baidu Green Luo chain function is still content tend to small and beautiful. The specific actions are as follows:

1: Outside the CHAIN keyword diversity main keywords will only account for all the chain anchor text 30%, the rest of the use of common words, that is: Click here, the next page, see more.

2: Internal page Connection two-way inner page connection. The first is to get the connection from the outside to the inside page of the website, one is to get the connection from the content inside the external website. No longer limited to the home page interchange.

3: The chain content for the main station of all outside the chain are using manual editing fluent and readable false original articles, do not seek more, only can be read, can be included.

4: Tool use tool not directly to the main station, but to WEB2, free blog and other high-quality content as the goal, indirectly affect the main station.

5: Enhance the social sharing of the revised content typesetting, highlighting the social sharing function, guide users to share the collection, increase the content of the impact on the social web site.

6: To increase the short section due to the lack of personnel, most of the content is still copied collection. Need to add a short original column, simple and easy to operate high.

Because it is personal operation, according to the actual situation such as time and energy, only do the above simple plan.

Whether it is a panda, or penguins, or now we pay attention to the Baidu Green Luo algorithm, in fact, are search engines for the survival of the battle, webmaster should not use the feelings of complaining to treat. Search engine to maintain the quality of content, the webmaster will need traffic. Perhaps, the webmaster should become the search engine's friend, but is not the traffic battlefield enemy.
