搜索引擎如何查看动态配置文件? [英] How do search engines see dynamic profiles?

问题描述

最近搜索引擎已经能够在社交网站上分页动态内容.我想了解这是如何完成的.是否有像 Facebook 这样的网站创建的静态页面半频繁地更新.Google 是否尝试存储所有可能的用户名?

Recently search engines have been able to page dynamic content on social networking sites. I would like to understand how this is done. Are there static pages created by a site like Facebook that update semi frequently. Does Google attempt to store every possible user name?

据我所知，像 www.facebook.com/username 这样的页面并不是存储在磁盘上的实际文件，而是以下查询的简写:从用户中选择用户名并在页面上显示信息.谷歌如何了解每个用户，当涉及推文之类的事情时，这会变得更加复杂.

As I understand it, a page like www.facebook.com/username, is not an actual file stored on disk but is shorthand for a query like: select username from users and display the information on the page. How does Google know about every user, this gets even more complicated when things like tweets are involved.

我想我并没有真正问我想知道什么.我需要像 twitter 或 facebook 一样大才能让谷歌以特殊的方式抓取我的网站吗?如果我允许任何人查看我的用户个人资料，谷歌会自动找到它们吗?如果不是，我需要做什么才能使它工作?

I guess I didn't really ask what I wanted to know about. Do I need to be as big as twitter or facebook in order for google to make special ways to crawl my site? Will google automatically find my users profiles if I allow anyone to view them? If not what do I have to do to make that work?

推荐答案

特别是在推文的情况下，谷歌并不是传统意义上的爬行"；他们与 Twitter 集成 实时提供搜索结果.

In the case of tweets in particular, Google isn't 'crawling' for them in the traditional sense; they've integrated with Twitter to provide the search results in real-time.

在您的问题的更一般情况下，动态内容对于 Facebook 或 Twitter 来说并不新鲜，尽管它可能看起来如此.谷歌抓取一个网址；URL 提供 HTML 数据；谷歌索引它.无论是呈现页面的动态查询，还是静态 HTML 的缓存，理论上都对索引过程没有什么影响.在实践中，还有更多内容(参见 Michael B 的评论)下面.)

In the more general case of your question, dynamic content is not new to Facebook or Twitter, though it may seem to be. Google crawls a URL; the URL provides HTML data; Google indexes it. Whether it's a dynamic query that's rendering the page, or whether it's a cache of static HTML, makes little difference to the indexing process in theory. In practice, there's a lot more to it (see Michael B's comment below.)

查看 Vatec 的简洁帖子，了解 Google 如何在不实际登录和浏览 FB 的情况下找到所有这些公开的 Facebook 个人资料.

And see Vartec's succinct post on how Google might find all those public Facebook profiles without actually logging in and poking around FB.

好吧，这过于简单化了，但让我们看看人们还有什么要说的..

OK, that was vastly oversimplified, but let's see what else people have to say..
