Do SEO is to do relevance

When a search engine searches for a keyword, it usually returns a large number of pages, which are arranged in a relatively fixed order for us to read and click. This amount of clicks affects the traffic of the site represented by the entry. As a site contractor, of course, want to profit from the site. But no matter how you make the site profitable, traffic is the basis. To improve the flow of the site, so that their site's entry ranking on the front will be an effective good way-this is the main goal of SEO. The factors that determine the order of the entries are called correlations, and the higher the relevance, the better the ranking. It can be said that doing SEO is actually to do relevance-let the site page with a large number of people search the keyword to establish a high correlation, the site traffic will naturally improve.

However, determining the relevance of a page to a keyword is not so simple, because this is the search engine's core technology and top secret, others can not easily know. It is said that only three to five people in Google know about Google's full relevance algorithm, which is certainly suitable for other search engines as well. In other words, we can not thoroughly understand the search engine relevance algorithm. But do not lose heart, although we have no way to thoroughly understand the search engine relevance algorithm, but from the search engine's purpose is not difficult to introduce some rules.

Search engines are designed to enable users to quickly find interesting content in the vast web world by searching for relevant keywords. Search engine to judge a content is not interested in the user, is to determine whether the content and his search for the keyword-related, the higher the relevance, the more likely that this content is interested in users, in order to give users want, the natural ranking is the more forward. To illustrate this issue, here's a real-world example to illustrate:

The birth of a brilliant doctor

In the real world, we judge Dr. Wang is not a good doctor, can start from several aspects: 1. Dr. Wang himself said he was a good doctor; 2. Many people say Dr. Wang is a good doctor, and even many doctors, especially the medical profession, say the Doctor is a doctor; 3. Dr. Wang is very busy, Healed a lot of difficult and incurable patients, received a lot of banners. Through the 1th, we think Dr. Wang may be a doctor, or maybe not, because Wang Po may sell melon puff. Through the 2nd, authoritative certification, Dr. Wang may be the probability of a good doctor increased a lot. Through the 3rd, the facts show that we can be sure that Dr. Wang is a doctor. If someone is looking for a doctor, then you know he's actually looking for Dr. Wang.

If there are Dr. Lee, Dr. Zhao, Qian doctor, Dr. Sun have met these three conditions, how to sort? In fact, it is also very simple to deal with, for these three conditions each set a score, and then according to the total number of doctors to sort it. In the relationship with the key words "Doctor", if the doctor Wang's score is: 100+100+100=300, Dr. Li's score is: 99+100+100=299, Zhao Doctor's score: 99+99+100=298, money doctor's score: 99+99+99= 297, Dr. Sun's score is: 98+99+99=296, then someone to find a doctor, we can give him a form, which says: "Dr. Wang's first, Dr. Lee second, Dr. Zhao's third, money Doctor four, Dr. Sun."

Return to the search engine. Search Engine Judge a page and a keyword relevance can also start from three aspects: first, the content of this page and a keyword-related; the second is a lot of pages, related pages and even the authoritative page that this page is related to a keyword; third, this page is very popular with relevant people. Simple to say, the actual operation is not simple, the following discussion of these three aspects.

The impact of page content on relevance

When I go to school, I often listen to the teacher say "digress". With the knowledge of SEO to explain "digress" means: the composition of the content and key words are not relevant or too low correlation. To make a page relevant to a keyword, this composition cannot be irrelevant. Want to let a page and the key words "mobile phone" related, do not have the whole content around the "car" to write. However, not to digress is the basis, to improve the value of this parameter, it is necessary to write a good essay. To write a composition and no fixed mode, do SEO is also so. Some people put the keyword density and other dead rules are too important, in fact, SEO does not understand. In fact, as long as around a topic to do content, a topic clearly, the key words will naturally be introduced, essentially do not have to deliberately pursue what keyword density, if excessive pursuit of keyword density, resulting in the readability of the article, the SEO is not good.

Impact of external links on correlation

Outside the chain is a site SEO level of an important parameter, the more the number of chain to the site ranking the better. A few years ago, a site as long as there are enough outside the chain, even if the content is a mess can also get a good ranking. With the development of the search engine, the function of the outside chain is gradually reduced, and the correlation requirement is more and more high. There are two important parameters affecting the correlation of the outer chain, one is the content theme of the page where the link is, and the other is the anchor text used for the link (the point to be particularly noted here is that someone likes to write the keyword in English or Hanyu Pinyin in the form of a URL, in fact, in order to obtain a similar anchor text effect). To illustrate the role of these two parameters, the following examples illustrate.

Suppose a website is to do mobile phone, hope the keyword "mobile phone" get rank, there are outside the chain A, B, C, a link to the site is to do the mobile phone, B link site is to do medical, C-Link site is to do literature, then a link to improve a site and the key words "mobile phone" the relevance of the largest. If a, B link uses the anchor text "mobile phone" a word, C-link is just a simple link, then to improve a site and "mobile" relevance, a link to the largest role, the second link role, the role of the third link is minimal. If a link does not use anchor text, and B link uses "mobile phone" as anchor text, then A, B link which contribution is big? This question is left to the reader to think for themselves.

The impact of user behavior on relevance

The user's action on the search engine affects the relevance of the site. Suppose that there are 10,000 users in Baidu search keyword "mobile phone", of which 6,000 people directly click on the second site, then the search engine will be ranked second site and the keyword "mobile" more relevant (title will also affect the click Rate, more on the title of the content, please read the capture Wen " Carefully write a good website Title,seo optimization success half "). In another case, if the user clicks on the first site and then exits quickly, then clicks on the second-ranked site and stays on the second site for a longer period. Both of these situations will improve the ranking of the second site and the keyword "mobile" relevance, but the second situation will weaken the first site and the keyword "mobile" relevance, because the user's behavior is obviously told the search engine, ranked first site is not what he is looking for.

Site PV and user dwell time will also have a positive impact on relevance. The higher the PV of the website, the longer the user stays, the greater the value of the website to the user. If it is a functional site, like the site's users will be bound to carry out a variety of operations, the inevitable cause of PV upgrade; If it is a content site, like the site users will need to spend more time to read. Most of the time, PV and stay time are proportional, because the operation itself takes more time.

There is also a situation where the user's sharing behavior affects relevance. A user search for a keyword, and then into a website, and finally the site's URL to share the social media, the whole process is not difficult to draw this keyword and this site related to this conclusion. Share once, that is to affirm once this kind of correlation, more people's sharing accumulates, is more people affirm this kind of correlation, accumulate over time, will have a big influence to the correlation. In fact, even if you do not consider this correlation, the only consideration of Baidu search results after the number of entries, it will have a positive impact on the click-through, it is worth us to install the share button. Crazy Brother recommended the installation of Baidu share button, it seems that only the installation Baidu share button, will be in the search results show this share number.

The article writes here is very near to the end, because the crazy male brother most hates dogmatism, therefore this article only discusses affects the correlation the factor and the principle, wants to use in the actual combat also to need the reader nimble application. In fact, because the crazy male brother can be limited, the examples of these factors may not be complete (not correct), to become a master SEO, but also need readers to further explore and think, and constantly absorb nutrients from the practice.
