The working principle of the search engine

SEO, translated into Chinese is search engine optimization. SEO before you have to understand some of the basic principles of search engine work. We want to do the job is to make their own site in line with search engine search habits, improve the search engine on the site's friendliness, so that the engine for the site to bring traffic. Search engine algorithm In addition to a very small number of internal staff, no one can know their algorithm, we can do is to test, the search engine to enter some search instructions, see what the result is, so as to infer some of its basic working principles, Research on search engine optimization is actually the reverse inference of search engine work process. Therefore, learning search engine optimization should start from the basic principle of the search engine work.

Search Engine Basic working principle is: Crawl, index, sort.

Crawl, first search engine set up a Chinese called "Spider" (or robot) program, this "spider" will follow the link path to the various sites it can go to crawl some Web pages, save into the search engine database, for some of the pages it feels good may also come to see whether there are updated information and so on. Index, the search engine set up an analysis program to analyze the collected pages, including the URL of the site, the site's tags (title tags, keyword tags, description tags), and content encoding details, and then according to a set of work procedures to calculate their classification and analysis of the content of the relevance of certain words, And then stored in the database. Sorting, when the user input search instructions in the search engine, they will make a judgment on the instructions and then from the database to find the corresponding classification of the pages and their relevance to the importance of a sort.

The basic working principle of search engines is this.

Second, in-Station optimization

After understanding some basic working principle of search engine, we should make some detailed analysis on it.

1, a reasonable and simple title and the relevance of the content, many people will be the title written very long, this is actually a search engine is very bad, search engine difficult to determine the Web page on the user's search instructions to the relevance of how high. For example, a customer wants to buy a pair of myopia glasses, she went to the street, see signs on the written there is a certain glasses shop, will be very generous into the consultation to buy. If the shop signs that we have glasses, cigarettes, hardware, shampoo and other commodities, price concessions, welcome to buy. Then the customer will not necessarily go in.

2, advertising and external information to take the call, in the process of website optimization, it is unavoidable to reference some external resources or advertisements on their website, but directly to the code will lead to the code too many, will affect the speed of the spider access, and then cause some unnecessary impact, So we can use JS call and other methods to solve. There is not to decorate the site too loud, as simple as possible, so that not only a good user experience and the search engine is also extremely friendly.

3, the content of the king, outside the chain for the emperor. SEO is not so complicated, we think it is too complicated. SEO Basic Most important is two points, one is content, one is outside the chain. This simple principle is applied to an enterprise, content is equal to the quality of the product, quality is an enterprise existence of the fundamental, whether it is a tangible product or intangible products, so we do the site or to be their own site content to do first, the chain is equivalent to advertising, an enterprise product quality again good, Who knows, have to rely on publicity, propaganda people just know how good your products, the kind of wine is not afraid of the deep lane of the era has long passed. We are on each site to send their own outside the chain, in fact, is to advertise, this advertisement on the engine useful to the user also useful, so we also want to build a good site some external links.

4, the picture attribute problem, the website does not put too many flash and so on picture, because the search engine currently to the picture attribute is unrecognized, the engine to the picture attribute recognition the only method is through the ALT to the picture description to judge the picture.

5, reasonable and effective to do the site links, hyperlink links to the URL link and Miao text links, some of the pages in the site, there are other pages related to the keyword, you can add some hyperlinks to the relevant pages, thereby increasing the weight of the page, so that the page in the engine index to get a better ranking , because you add a hyperlink that is tantamount to a vote of trust to the page.

Well, SEO optimization no one else said so God, SEO is to do some simple things repeatedly do, adhere to do will be successful, remember: SEO no shortcuts, your implementation.
