搜索引擎是怎么工作 How Search Engines Work

Before we can talk about everything that makes up SEO, we’ve got to start with the basics – how the internet and search engines work.

在我们初步构成SEO的所有内容之前，我们必须从基础开始–互联网和搜索引擎如何工作。

Boiled down to the simplest concept, the internet is really just a huge collection of pages that are connected by links. I like to use cities as a metaphor – a website is like a house, where each room in the house is a different page on the site, with hallways and stairs connecting the different rooms, but therooms add up to a cohesive whole. You have different houses on the street, but everything in the neighborhood is related. If you add even more houses, you end up with a city .

归结为最简单的概念，互联网实际上只是一个由链接连接的大量页面集合。我喜欢用城市作为比喻–一个网站就像一个房子，房子里的每个房间都是网站上的不同页面，走廊和楼梯连接不同的房间，但房间加起来是一个有凝聚力的整体。你在街上有不同的房子，但附近的一切都是相关的。如果你添加更多的房屋，你最终会得到一个城市。

Think of links like roads – they connect the different buildings and neighborhoods together. A big popular website is like a large office building, with lots of roads leading to it. It’s easy to see, and there are plenty of different ways to get there.

一个很受欢迎的网站就像一座大型办公楼，有很多变成它的道路。这很容易看到，有很多不同的方法可以达到目的。

If you’re building a new site, it’s like you’re adding a new building to the city. Where would you rather have that building? If you’re right on the intersection of the freeway and several cross streets, it’ll be a popular location that’s easy to find. But if you build it way outside of town in the middle of a huge field, no one will know it’s there.

如果您正在建设一个新网站，就像您正在为该城市添加一座新建筑。你想在哪里建造基础建筑？如果您在高速公路和几条十字路口的交叉路口，那么是一个很容易找到的热门地点。但是如果你在一个巨大的田野中间建造它的方式，没有人会知道它在那里。

Back in the beginning of the World Wide Web, when there weren’t that many sites, you could only reach a website by typing in the address of the page or by clicking a link on another site.

回到地球的开头，当没有那么多网站时，您只能通过输入页面地址或点击其他网站上的链接来访问网站。

In the early 90s, the web had grown too large to sustain such a simple navigation and discovery process. The first search engines were born – now users could type keywords into the search engine and receive a list of websites related to the search phrase. Excite , AltaVista, and Yahoo! quickly changed the way that people were using the internet.

在90年代初期，网络已经变得太大，无法维持这种简单的导航和发现过程。第一批搜索引擎诞生了–现在用户可以在搜索引擎中键入关键字并接收与搜索相关的网站列表。Excite，AltaVista和Yaa！快速改变了人们使用互联网的方式。

In the late 90s, Larry Page and Sergey Brin were working on their own search engine, and they were the first to use links as a signal of authority and trust. WhenGoogle was finally released, it quickly became the favored search engine because the quality of the search results far surpassed the other options.

The search engines created advanced algorithms that analyze hundreds of factors for each website – both on and off the website. The algorithms are constantly updated and adjusted to ensure that search results are the best they can be.

搜索引擎创建了高级算法，可以分析每个网站的多个因素–包括网站内外。算法会不断更新和调整，以确保搜索结果最佳。
