Baidu ranked a variety of factors accounted for the proportion of analysis

Baidu ranking of the final formula is:
1, ∫ is an integral symbol, C = content, L = link, K = keywords, O = others. SEO is a long-term "time" integral process, the content is the core;
2, C1-rich content is the first element, in accordance with the original, pseudo-original, reproduced in order to meet the importance of content to meet the user experience;
3, L2-link reasonable and rich is the second element, a reasonable and effective internal links and rich external links are equally important, and external links are highly relevant Pr value pages is particularly important;
4, K3-key factor is the third important factor, including: reasonable Title, Description, Keywords, page keyword and related keyword density and reasonable layout;
5, O4 - other factors, such as: domain name, age, server, site architecture, typesetting, neighbors, Url, maps and so on;
This formula is a very general description of SEO optimization, SEO optimization need to be aware of the problems are taken into account.
According to this formula, you can find a lot of valuable concepts, interested friends can taste carefully taste, but the premise is that you have to understand the formula This formula in mathematics, called the indefinite integral formula, if the formula is written as Integral formula, then, huh, huh, that effect is great, but in this case, it is transparent SEO optimization.
SEOer seems to be very concerned about the spider experience, in fact, the user experience is also very important. I use the following formula to sum up:
SEO = user experience + spider experience. SEO / SEM theorem: SEO / SEM = UE + SE;

The following order from heavy to secondary arrangement:
1, the site's external chain probably occupy 20%
I believe we all know that sentence outside the chain as the king, the content of the classic king, a lot of time the quality and quantity of the site outside the chain to a certain extent affect the website keyword rankings. Foreign chain in the entire optimization rankings accounted for the largest proportion, so many of my friends take the risk, to buy black chain, mass external chain. In fact, the website of the chain is not better, more important than the quality of the chain.
2, website domain name registration time accounted for 20%
This incident I recently discovered, I recently engage in foreign network site keywords: Guangzhou website construction rankings, my site personally think that both the external chain, content originality, the site open speed and so on the factors to compare My site is stronger than the opponent's site, it is not on the Baidu Home. After this period of observation, I found that rivals' websites are all older than 2006, and my registration is in 2008. In this regard, I believe it is short-lived, and it is estimated that Baidu is content-based. Time domain name website ranking is only temporary.
3, the site's chain accounts for 10%
The inner link is in the web content keywords plus links to the corresponding page. This inner chain accounts for 10% of the entire scale. In fact, a manifestation of our users, Baidu Encyclopedia is the use of this chain, so we do Chinese website Baidu ranking is still very necessary reference to Baidu's products. One thing to note is that the number of links within the site should not be too many, usually a thousand words of articles, up to 4 times the chain appears.
4, website content update accounted for 10%
General content updates include updated frequency and content quality, update frequency I believe we all know, is like a feeding for children, if you feed too much, fed a few days a second, such children can Healthy growth? The content update frequency is best updated daily, time is sufficient, update two or three times a day. Update time is generally 8.9 o'clock in the morning, 5.6 o'clock in the afternoon, there is about 10 o'clock in the evening, these spiders are more frequent. As content quality is nothing more than asking everyone original, the best number of words in the article remained at 300 words or more, to match the keywords of the site, such as website construction, do not write a medical technology. Reduce the readability of users, to a certain extent, affect netizens' re-visit.
5, website traffic accounted for 10%
This point, I deeply understand, I have a web site in the past is to do video broadcast, you search the central five broadcast, and now still in the home, because the site's keywords have not yet jump to the current site content, so every day The traffic to my site has dozens of separate IPs. Although I made this website now site made content sites, due to the daily traffic has a certain amount of Keywords Keywords: to do the site, do a few companies such as website ranking has always been the home page.
6, website layout and website speed accounted for 10%
I believe this is also very easy to understand, often a successful site, the layout will be considered when the good, how beautiful and generous and practical, with the most simple page, the fastest speed to tell customers what to provide this site services, products . This problem can basically be fixed in the initial stage of website construction.
And the remaining 20% ​​is the site's space server turn on speed, ALEXA global rankings, website PR value, and a few other things. These are some of the ranking algorithms I've recently discovered, but the Baidu ranking algorithms are constantly changing, and some factors may be accurate for the time period and have changed over time. These may be some of these people will be recognized, there are also that bad, I hope you help out.
