The most likely reason is that Baidu database has been updated. If this is the case, you should not worry too much, because such updates will not affect Website construction Of SEO situation. It is also rumored that Baidu is moving its database. It is expected to complete this huge work by the beginning of July. Let me wait patiently!

I believe you still remember Baidu K Station on 6.22. Because the K station is already a large area this time, and most of the old stations are suddenly raised to a very forward position by some new stations that are not well done by K SEO in the same period. Recently, I have been communicating and speculating with many friends who do SEO. Many people complain that Baidu K is a bit baffling this time, because most of the websites that follow Baidu's search engine optimization guidelines have been demoted. For example, I have sniffed the Rose blog and basically haven't optimized it. I only occasionally update and publish SEO articles, which is not cheating and over optimizing. Of course, It is understandable that the change of Baidu's algorithm has just given some new stations the advantage of focusing on some aspects and punished some old stations with too heavy optimization traces in optimization techniques, but today's second wave of K stations has made many friends unable to understand that they came up in the morning, and almost all groups related to SEO are talking about whether the website has been K like frying pan

At present, the number of visits to posts has exceeded 2800. First, let's take a look at the votes launched by the seouchi forum. Voting was initiated by the webmaster Lone Wolf SEO and soon became a hot topic. As of my screenshot, 324 webmasters have voted. The voting results are as follows. 232 webmasters have been K, accounting for 71.6% of all the people

vote

Although it can also explain the wide area of K, this simple vote may be a bit one-sided. But it is not enough. Next, let's see that chinaz gives me an SEO vane through its database. There is a data item (total number of data sampling stations: 575710K stations account for 2.29% of the total number of data sampling stations, while the average proportion of the previous K stations has always been more than 0.2%. It has suddenly increased by more than 10 times, so we can imagine that the website is covered by K

Chinaz data vane: the proportion of websites targeted

The main guesses are as follows: carefully collected the discussion on the reasons of K station in various forums.

1. A large number of collected or low-quality pseudo original content;

2. Cheating external chain operation of mass sending links or buying links;

The keyword density is too high.;

If filing, 4 website space problems. Server stability, etc;

5 Operation of medical stations or stations in a sensitive industry;

6Web2.0 sites are affected by spam information;

7 Baidu's own database is updated.

According to my understanding, these are rare reasons. Personally, I prefer the last point, because there are many signs that this K station is totally unreasonable. Here are some reasons to summarize:

It can't be said that it is unprecedented. The area of 1K station is vast. At least 2.29% of the websites listed on the Chinese Internet have been K dropped, and tens of thousands of websites have been K dropped, which is a disaster for SEOs and webmasters. K site involves all walks of life, although there is also a large area of medical treatment

Look at the famous SEO forum post after drinking, 2 famous websites in the industry have been lost by K, just for the SEO industry. A5 The blog of Tang Shijun's eldest brother has been knocked out of the website by K, not to mention how good the optimization method is, but at least it will not use cheating. If it is knocked out by K, it will be a bit abnormal

Although each website optimizer may have different technical means, 3 K websites are mostly optimized by dedicated SEO staff. There may be a lack of correct understanding of SEO, but the website can't be killed because of an algorithm update.
