First of all, the so-called "tag algorithm" is only a comparison of the selection of the title of the update, not Baidu search engine official out of the latest keyword sorting algorithm, plainly, is that the Baidu update algorithm is more appropriate to use this "tag algorithm" nickname. So let's call it a moment, and ask your little friends not to misunderstand. Although the Baidu update is not in the official what algorithm notice, but according to the real data to speculate that the so-called "tag algorithm" is still relatively close.
Analysis on the reason of the mass website being lowered in May 2015
1, the site's internal optimization is not good enough
TKD Optimization: The current site title tags and introduction tags are participating in the Site keyword ranking, but we need to use reasonable, if you in the title tag and the introduction tag in a large number of keywords, will be easily punished by the search engine, although there may be a temporary good effect, but definitely not worth it. The title tag of the website should be fine, simple, short, so that more value, the site introduction tag contains 1-3 keywords in the title, only coordinate well to play a greater effect.
H1 Label Optimization: Although the site of the H1 tag can effectively improve the keyword rankings, but definitely not because of the effect of the frequent use, in fact, the so-called effect is probably just a period of time, it is because the search engine has not been found, once the search engine will give you a surprise. Suggest a page H1 label only use 1 times, of course, you can use H2 or H3 label, the effect is very good, must be reasonable use.
Dead chain optimization: Regular inspection of the site's internal chain connectivity, once found that the station has a dead chain to be submitted to the Baidu Webmaster platform to deal with, so as not to touch the search engine down the right rules, resulting in the ranking down the site is punished/down right.
Content Quality Optimization: At present, Baidu search engine for this kind of work is more serious, as far as possible to update some of the original valuable content, do not for the amount of content to make a large number of copy and paste, generally the content of the similarity is recommended not more than 50% is better.
Internal chain optimization: in-station article within the chain recommendations control in 3 or so, it is best to be able to grasp the relevance of the link word, so that your users read this article will click on the link in this article, so as to better reflect the quality of the chain within the site.
Page keyword Density optimization: A page appears a large number of keyword stuffing, usually the keyword density in the 1%-4% can, do not in order to quickly improve the rankings and to accumulate a large number of keywords, so it is easy to be the search engine to be convicted of cheating suspects.
2. Poor quality of the external chain of the website
Links outside the chain: usually we will say that the link is a high-quality chain, but I think not necessarily, why? Because when you exchange a cheat site link, then your website is to be seriously affected, so, we in the Exchange site links when must pay attention to the quality of the other site, If the other side of the site quality is not what (there is a suspicion of cheating), then we would rather not change this friendship link. There is that we need to regularly detect the link on their website is abnormal, such as the discovery of links in the site of the right to fall, we should notify the other webmaster and temporarily cancel links, so as to avoid their own site is implicated punishment.
In order to chain outside the chain: found that a lot of small partners are more like crazy to do outside the chain, although the outside chain is still some effect, but this is also for high-quality outside the chain, garbage vulgar outside the chain basically no effect. What kind of outside chain is considered high quality? The author's understanding is that the more times the chain is clicked by the user the more it is easy to prove that this is a valuable outside chain, because it can really help users solve some problems. Please remember a little, do not do outside the chain to do outside the chain, we should be to help other people to do the outside chain.
3, excessive SEO optimization caused
What is called over-seo optimization? In fact, you have the pain of the egg, all of your site can optimize the part of all optimization, and even some can not optimize the part of the optimization, such as: the bottom of the page there is a lot of meaningless anchor text links, TKD piling keywords, the content of the article deliberately to repeat the key words, In order to quickly reach the effect in the short term, in a short period of time to increase the chain, when the achievement of their desired results and then stop the increase of the chain and so on, these are part of the excessive SEO optimization behavior.
4, the website is not safe to appear the loophole
The security aspects of a website is extremely important, when your website page by some so-called "hacker" intrusion, or the occurrence of dangerous loopholes are exploited, then your site may be at any time the risk of paralysis, if you are hung up some of the user has an impact on the "virus" code or something, the search engine will certainly take measures in time, The right to fall is a slight act. Therefore, the website security must pay attention to.
SEO thinking Optimization site must kill technology
Recycle trend Time SEO thinking
It sounds like a little bit of a feeling, but in fact this SEO thinking is so, I called the "cycle of the current era" SEO thinking means that now everyone's life is very good, the overall promotion of a lot, but people began to slowly yearn for the past life, and often let people have a kind of circulation feeling, Not only is life so, such behavior is often reflected in the trend, we can think about it. In fact, we do SEO optimization is similar to this, although the search engine algorithm in the change of the update, but always inseparable from a number of primitive foundation, often is a big circle of the end or around back, so, no matter how the algorithm changes, we just need to do those basic optimization to ensure that the bottom line adhere to go down.
Optimizing SEO thinking with precision and intentions
I believe that we are "accurate" and "intentions" two words are not unfamiliar, in fact, think carefully about doing anything is so, do not ask for a large quantity, only accurate, hard to get more people's recognition. Either do or do not, since done must be good intentions to treat, because everyone is not a fool, there is no one eye can see, like my blog, there is no intention to believe that everyone can see, I think if you want to do a good word of mouth is also very important.
Summary: If your website has some of the symptoms mentioned above, then I hope you can adjust, insist on doing the normal maintenance work, I believe the site will be restored as soon as possible. The ultimate goal of search engine optimization is for the user experience, the real help users solve the problem, that we are in conjunction with the search engine algorithm, but also to do a good user experience, to help users really solve the problem as the core to do SEO optimization, for ta people to bring help while also help yourself.
