搜索引擎是如何工作的?

来源:www.sjkhdkf.com 发布时间:2017/08/23

搜索引擎优化是搜索引擎不是人的思维方式,这对于每个人来说都是显而易见的,人的主观和搜索引擎如何浏览网页是不同的,搜索引擎是文本驱动的。随着科技的不断发展,搜索引擎远远不能智能的搜索,搜索引擎抓取网页寻找特定的网站项目,从而获得一个网站是什么样的推广想法。

Search engine optimization search engine is not people's way of thinking, this is obviously for each person, the subjective and the search engine how to browse the web is different, the search engine is a text driven. With the continuous development of science and technology, search engines are far from intelligent search, search engines crawl web pages, search for specific web sites, and thus get a website is what kind of promotion ideas.

章丘网络推广

首先,章丘网络推广公司针对搜索引擎抓取网页,是先看看有什么。这个任务是由一个软件进行的,称为爬虫或蜘蛛。蜘蛛遵循从一个页面到另一个页面的链接和索引以及每一个他们能找到的方式。想到网站推广公司的网页数量,因为蜘蛛每天去访问一个网站,每天去看是否出现了新的一页,或者有一个现有的网页已被修改,这是不可能的,有时,爬虫可能最终不会一个月或两个月访问你的网站。
First of all, Zhangqiu network promotion company for search engines crawl web pages, is to see what there is. This task is performed by a software called crawler or spider. Spiders follow links and indexes from one page to another, as well as every way they can find them. Think of the number of web pages of website promotion company, for a spider to visit a web site every day, every day to see whether there is a new page, or an existing web page has been modified, this is not possible, sometimes, the crawler may not end up with a month or two to access your site.
正如我们已经提到的,爬虫不是人类它们看不到图片,Flash,JavaScript,密码保护的页面和目录,所以你最好跑下蜘蛛模拟器看看。在页面被抓取后,下一步是索引其内容。索引页面存储在一个巨大的数据库中,从那里可以检索到。从本质上讲,索引的过程是确定最佳的描述页面和分配页面,特别是关键字和表达式。
As we have already mentioned, reptiles are not human. They can't see pictures, Flash, JavaScript, password protected pages and directories, so you'd better run down the Spider Simulator to see. After the page is crawled, the next step is to index its contents. Index pages are stored in a huge database that can be retrieved from there. In essence, indexing is the process of determining the best description pages and distribution pages, especially keywords and expressions.
对于一个人来说,处理这些信息是不可能的,但是一般的搜索引擎都会处理好这个任务。有时他们可能没有得到一个页面的意思,但如果你帮助他们优化,它会更容易为他们正确分类你的页面,以获得更高的排名。
It is impossible for a person to process the information, but the general search engine handles the task well. Sometimes they may not get the meaning of a page, but if you help them optimize it, it will be easier for them to correctly classify your pages in order to get higher rankings.
在搜索请求时,它将搜索请求中的搜索字符串与数据库中的索引页进行比较。因为它很可能不止一页包含搜索字符串,搜索引擎开始计算其索引中的每一个页面的关联度与搜索字符串。
When searching the request, it compares the search string in the search request to the index page in the database. Since it is likely that more than one page contains search strings, the search engine starts to calculate the relevancy of each page in the index and the search string.
有不同的算法来计算相关性。这些算法有共同因素,如关键字密度,不同的相对权重的链接,或元标记。这就是为什么不同的搜索引擎会给出不同的搜索结果,搜索结果页面的相同的搜索字符串。
There are different algorithms to compute correlation. These algorithms have common factors such as keyword density, different relative weights of links, or meta tags. That's why different search engines give different search results, the same search string for the search results page.
