seo优化中,你知道蜘蛛怎么抓取吗?

来源:www.sjkhdkf.com 发布时间:2017/08/10

爬行是一个搜索引擎蜘蛛从一个已知的页面中解出一个URL的过程,然后跟踪一个链接来发现一个新页面。当然,蜘蛛并不是为了在过去找到新的URL,而是为了找到存储库中的地址的URL地址,这是一个爬行器,它可以从地址库中抓取提取的URL地址。
Crawling is a search engine spider that solves a URL from a known page, and then tracks a link to find a new page. Of course, spiders are not trying to find new URL in the past, but to find the URL address of the address in the repository. This is a crawler that grabs the extracted URL addresses from the address library.

抓取是搜索引擎爬行器从地址库抓取的URL,访问URL,并将读取的HTML代码存储到数据库中。爬行器的爬行就像打开页面的浏览器,以及用户的浏览器,并在服务器的原始日志中留下记录。

Crawl is the search engine crawler crawling from the address library URL, access to URL, and read the HTML code stored in the database. Crawlers crawl like the browser that opens the page, as well as the user's browser, and logs in the original log of the server.
索引指的是将一个URL的信息分类到数据库中,这是索引库。当用户搜索时,搜索引擎从索引库中提取URL信息并对其进行排序。英语索引是索引。索引库用于搜索,因此索引的url可以被用户搜索,而未索引的url在搜索结果中是不可见的。
Indexing refers to classifying an URL's information into a database, which is an index library. When a user searches, the search engine extracts and sorts the URL information from the index library. The English index is the index. The index library is used for the search, so the index URL can be searched by the user, and the index URL is not visible in the search result.
一个URL的信息是不限于蜘蛛抓取的URL,以及来自其他来源的信息,如外部链接,链接锚,等等。有时候,这个URL的信息在索引库中没有捕获任何东西从这个URL,但搜索引擎知道URL存在,有一些其他信息。
The information of an URL is not limited to spiders grabbing URL, as well as information from other sources, such as external links, link anchors, and so on. Sometimes, this URL information does not capture anything in the index library from this URL, but the search engine knows that URL exists and has some other information.
