Old Xie Research website promotion for many years, SEO is a very good promotion. Webmaster Study SEO Interest is also very high, which is very good, because SEO can directly bring traffic to your site. But old Xie thought that we study the SEO the thought can replace, this effect should be better.

SEO is a technology based on search engine. We're working on it as a black box to study the search engine, which means that we're betting on a root that doesn't understand its basic workings. We take it as the result of our experience. Touch the stone across the river, just imagine, if we know the ' river ' flow, and depth, to our research is very favorable. But now our thinking has been set, so that our SEO technology can not appear the quality of the overflight!

Although we do not fully understand the full operation of the search engine, but we assume that its operating process, through the results of validation. Is this method better?

Search engine is a working principle process, I have studied it for a long time, but some basic things that we must understand.

Search engine can be divided into 2 kinds, Full-text search engine and directory index.

In the Search engine classification section We mentioned the full text search engine from the site to extract information to build a Web database concept. The search engine's automatic information collection function is divided into two kinds. One is a regular search, that is, every once in a while (such as Google is usually 28 days), search engine actively sent "spider" Program, a certain IP address range of Internet stations to retrieve, once found a new site, it will automatically extract the site's information and Web site to join their own database.

The other is to submit web search, that is, the site owner actively to the search engine to submit the Web site, it in a certain period of time (2 days to several months) directed to your site sent "spider" Program, scan your site and the relevant information into the database, in case the user inquiries. As a result of the search engine indexing rules have changed a lot in recent years, unsolicited Web site does not guarantee your website access to the search engine database, so the best way is to get some external links, so that search engines have more opportunities to find you and automatically your site included. "Spider" Program it has a lot of mysteries waiting for us to find out, if the study of good it, we can imagine how much of the SEO will change words.

When a user searches for information with a keyword, search engine will be in the database search, if found with the user requirements of the content of the site, then use a special algorithm-usually according to the page of the keyword matching degree, the position/frequency, link quality, etc.-to calculate the relevance of each page and ranking level, The links are then returned to the user in order, depending on the degree of relevance.

There are many differences in catalog indexing compared to Full-text search engines.

First, search engines belong to automatic Web site retrieval, while directory indexing relies entirely on manual operations. After the user submits the site, the directory editor will personally visit your site and then decide whether to accept your site based on a set of criteria and even the editors ' subjective impressions.

Second, the search engine included the site, as long as the site itself does not violate the relevant rules, the general can log in successfully. Directory indexing is a much higher requirement for web sites, and sometimes it may not be successful even if you log on multiple times. Especially Yahoo! such as Super Index, login is more difficult. (Due to login Yahoo! is the most difficult, and it is business Network marketing battleground.

In addition, when you log in to search engines, we generally do not have to consider the classification of the site, and the login directory index must put the site in a most appropriate directory.

Search engine information about each site is automatically extracted from the user's web page, so the user's point of view, we have more autonomy, while the directory index requires the need to manually fill out the site information, but also a variety of restrictions. What's more, if the staff think you submitted the site's directory, website information is not appropriate, he can adjust it at any time, of course, will not discuss with you beforehand.

Old Xie here just as a scratch, more search engine principle, waiting for us to study, to find, Lao Xie also very much hope that with some high-level search engine enthusiasts to exchange. Old Xie QQ466715240.
