another five or six days to start school, find out about search engine rankings, the following this article is still relatively good, first praise a ^_^! Search Engine Ranking Definition: Enter a keyword in the search engine, usually get a lot of search results, the ranking of these search results have successively points, this is the search engine ranking search engine ranking principle SEO, referring to the user-friendly and search engine based on the algorithm,   Use the site or outside the site optimization means, so that the site in search engine keyword ranking to improve, so as to obtain target search traffic, and then establish direct sales or establish network brand. Search engine rankings are basically divided into four steps: 1. Crawling and crawlingThe search engine sends out a program that can find new Web pages and grab files online, a program that is often called a spider. The search engine, starting from a known database, accesses these pages and crawls the files like normal users ' browsers. Search engines track links in Web pages and access more Web pages, and this process is called crawling. These new URLs will be stored in the database waiting to be crawled. So tracking web links is the most basic way search engine spiders find new URLs, so Reverse LinkBecome one of the most fundamental factors in search engine optimization.   No backlinks, search engines even the page can not find, not to mention the rankings. Search engine crawl of the page file and the user's browser get exactly the same, grab the file into the database. 2. IndexSpider Crawl page file decomposition, analysis, and in the form of huge tables into the database, the process is both index. In the index database, Web page text content, keywords appear location, font, color, bold, italic and other related information have a corresponding record. 3. Search word processingUsers in the search engine interface input keywords, click the "Search" button, the search engine program is to deal with searching words, such as Chinese-specific word processing, remove the stop word, determine whether it is necessary to initiate integrated search, to determine whether there are spelling errors or typos and other situations. The search term must be handled very quickly. 4. SortingAfter the search word is processed, the search engine program starts to work, finds all the pages that contain the search terms from the index database, and calculates which pages should be in front based on the ranking algorithm, and then returns to the search page in a certain format. No good search engine can be compared with people, this is why the site to search engine optimization.  Without the help of SEO, search engines often do not return the most relevant, authoritative, and useful information correctly. Factors affecting the search rankings of the domain name, server stability, keyword distribution density and distribution, site update frequency, the number of external chain, traffic ranking, user experience. Domain and host pairs SEO the Impact: The domain name and the host is the foundation of the website, the commercial website chooses the domain name and the host computer specially should pay attention to the image and the quality, for the network marketing carries on the solid foundation. At the same time, the choice of a good domain name and host is also the first step in search engine optimization. How the search engine determines the ranking between related sitesThis depends on a number of factors. In general, in order to have a keyword-containing page will have a high ranking, this keyword must appear in the page TITLEVolume label (TAG), METAThe volume label (TAG) KeywordsSection Descriptionsection, of course, must also appear in the Web content.   Remember that the search engine does not understand graphics, which means that the most critical text must appear in the HTML content itself. A growing number of search engines have ranked the popularity of site links as a determinant. That is, if your site is a lot of users linked to the object, and these links or links near the text contains some specific words, that these words can make your site better search rankings. For websites that have links to (English-language sites), there will be a "book" (books) of links or adjacent phrases. domain name selection and SEODomain name and IP: Each site's domain name corresponds to an IP address, which is a digital ID assigned to each computer or network device on the network. Domain names must be resolved by the Domain name server (DNS), converted to a digital IP, so that the computer can understand the identification, such as: 219.136.248.149 most of the SME Web site is stored in a server divided by a number of virtual host, a number of sites share a server and IP address, Some Web servers have hundreds of domains sharing an IP address. This cost to the webmaster is lower, but the search engine rankings for the site brings the following potential risks: 1 , other sites that share the host are punished by search engines and will spread more or less to your site. If a website is cheating under the same IP, then our search engine will punish all sites under that IP.   Fortunately, most search engines are less judgmental, such as Google, which is generally not subject to such collateral penalties. Conclusion: The domain name weight is high year old, the server is stable enough, is one of the important factors to get good rankings! 2 . The density and distribution of keywords. Want to get a better ranking, the optimization of the internal structure of the site is one of the key, like 126 mailbox cases, the keyword density, and distribution control of the good, the chain is not strong, can still get high rankings. 3 . Site Update frequency. The faster the website update frequency, it proves that you attach great importance to the site, you value your site, the search engine is also attached importance to. Why would ADMIN5 have such weights? It's a certain relationship with his update frequency. Google Ranking Formula Googlescore = (KW Usage score * 0.3) + (Domain strength * 0.25) + (Inbound Link score * 0.2 5) + (User Data * 0.1) + (Content Qualityscore * 0.1) + (Manual boosts) – (Automated & Manual Penalties) Translation: GOOGL E score = (Related keywords score X0.3) + (domain weight X0.25) + (outside chain score X0.25) + (user data X0.1) + (content Quality score X0.1) + (manual Plus)-(automatic or manual derating) factor analysis in the formula: from the formula we can clearly know, The factors that affect PageRank score are "Related keywords", "domain Name", "Outside Chain", "User Data", "Content quality" and "human intervention" in six aspects.   So what are the factors that affect these aspects?
