For enterprises building online service platforms, website traffic is the key to the success of websites. And the access to website traffic is closely related to search engines. Such commonly used search engines as Baidu, Sogou, 360, Google, etc. may not include all the information of enterprise websites. Without them, it is difficult to obtain good rankings. Inquiries and orders will also be affected, making it difficult to improve enterprise performance.
So, what is the principle of Baidu based search engine inclusion?
The working process of search engine is generally divided into three stages: crawling and crawling, preprocessing, and ranking.
1、 Spider crawling and grasping
In order to automatically crawl tens of thousands of web pages on the Internet, search engines must have fully automated page crawling tools. This program used to crawl and access pages is called spider or crawler. Spider is an important crawling technology of Baidu and other search engines, and also the source of websites. The source code is equivalent to its web, allowing it to crawl in the source code of any webpage.
When another new link is found in the source code, it will shuttle to another page through this link to continue crawling → crawling → crawling → crawling... so as to achieve the goal of web pages being included.
The higher the weight of a website, the higher the frequency of crawling by spiders. For new stations, the weight will be increased for at least 3 months to half a year. At the same time, the new station should maintain a high update frequency. If the new website does not update the content for a long time, and the spider does not find any new information that can be captured when it comes many times, it will slowly reduce the frequency of capture, from once a month to once a few months.
But in actual work, the bandwidth resources and time of spiders are limited, and it is impossible to crawl all pages. In fact, the largest search engine only crawls and includes a small part of the Internet.
2、 Pretreatment screening
Through spider crawling and crawling, the original database is established, and the search engine will extract text from the web page. In addition to the text displayed on the page, the search engine will also extract the text in such parts as meta tags, flash replacement files, anchor text, alt tags, etc. And for "de", "le", "ah" and so on Words without practical meaning, a large number of repetitive content and pages are eliminated, So as to improve the computational efficiency of search engines.
3、 Correlation calculation of ranking
The calculation of website ranking relevance is not based on the optimization of a single site or the click rate of a site, but the ranking given by search engines through various comprehensive scores.
1. Importance of keyword location
There are many tags in the source code of the website page. Some tags represent subtitles, and some represent pictures... When keywords appear in certain tag positions, the relevance between keywords and pages will be higher. These positions often include titles, bold fonts, picture Alt tags, and so on.
2. Anchor text keywords and link content
If we add our website pages to the matched keyword anchor text on external websites such as blogs, forums, and community platforms, it will be very helpful to improve page relevance.
3. The higher the page weight, the higher the import link relevance
If your website link can appear in an authoritative website, and links to anchor text keywords related to the website, the more relevant your page will be.
In recent years, in order to guide a wide range of reasonable SEO behavior, combat the use of malicious means to obtain rankings that are not consistent with the quality of web pages, and make the Internet ecosystem more healthy and orderly, Baidu and other major search engines have constantly improved their algorithm rules, which have a serious impact on user experience and the quality of search results, remove the weight obtained by cheating and reduce the weight of websites, Until it is completely cleared from the search results. Therefore, it is very important for enterprises to choose a professional search marketing team.
There is a benign symbiotic relationship between search engine algorithm rules and search marketing behavior. Professional search marketers will timely adjust the planning strategy according to the development needs of the enterprise, and use formal optimization means to do search marketing within the scope of the algorithm rules, so that the website can be included in the shortest time and obtain a stable ranking, so as to seize more successful websites and promote continuous business growth.
