SEO简明教程 第一章 分析搜索引擎概貌（6）

为什么对使用搜索引擎感到困惑？

为何您在市场活动中使用搜索引擎会有困惑？因为搜索引擎是新访问量的最重要来源。您也许听说过大多数的网站访问量是从搜索引擎开始引入的。恩，这个说法不是很准确。几年前这样说是正确的，现在许多人仍然引用这个过时的说法，是因为这个依据听起来不错：百分之八十的网站访问者是通过搜索引擎进入网站的。然而，在2003年，这个说法终于平息了。搜索引擎产生的流量跌破百分之五十的大关。大多数网站访问者要么在浏览器中直接输入目的网站的地址，要么是在其他的网站上点击了一个指向目标网站的链接。很多网站访问者在开始时并不是通过搜索引擎进入目标网站的。

然而，由于下列几个原因，搜索引擎仍然是相当重要：

1，来自搜索引擎的访问流量还是相当显著的，不久前，一份调查报告表明这个比例接近百分之五十，当然了，肯定不是百分之八十，不过这也是相当大的流量。EMarketer 2005年发布的一份报告说，在美国百分之二十一的网络用户每天使用搜索引擎四次以上；PEW Internet 估计大约有38万美国人每天使用搜索引擎。

2，iCrossing 在2005年做了一项研究，发现百分之四十的人在购买商品前先进行网上调查。

3，对于那些不是来源于搜索引擎的访问量，很大一部分是老用户，因为他们知道自己要访问的网站；很多新访问量是来自于搜索引擎，对于网站来说搜索引擎是最重要的一个来源。

4，一些研究表明很多购买者的购买行为是从搜索引擎开始的。根据iCrossing 2005年的一项调查，在所有计划在网上购买商品或者查找商品信息的人当中，大约有67%的人使用搜索引擎。

对于网站推广来说，搜索引擎是一种廉价的方式。一般来说，相对于其他的广告或市场营销方式，您可以通过免费的搜索引擎流量获取更多的收益。

英文原文：

Why bother with search engines?

Why bother using search engines for your marketing? Because search engines represent the single most important source of new Web site visitors.You may have heard that most Web site visits begin at a search engine. Well,this isn’t true. It was true several years ago, and many people continue to use these outdated statistics because they sound good - “80 percent of all Web site visitors reach the site through a search engine,” for instance. However, in 2003, that claim was finally put to rest. The number of search-originated site visits dropped below the 50-percent mark. Most Web site visitors reach their destinations by either typing a URL - a Web address - into their browsers and going there directly or by clicking a link on another site that takes them there. Most visitors don’t reach their destinations by starting at the search engines.

However, search engines are still extremely important for a number of reasons:

_ The proportion of visits originating at search engines is significant. Not so long ago, one survey put the number at almost 50 percent. Sure, it’s not 80 percent, but it’s still a lot of traffic. According to a report by eMarketer published early in 2005, 21 percent of American Internet users use a search engine four or more times each day; PEW Internet estimated that 38 million Americans use search engines every day.

_ A study by iCrossing in the summer of 2005 found that 40 percent of people do online research prior to purchasing products.

_ Of the visits that don’t originate at a search engine, a large proportion are revisits - people who know exactly where they want to go. This isn’t new business; it’s repeat business. Most new visits come through the search engines - that is, search engines are the single most important source of new visitors to Web sites.

_ Some studies indicate that a large number of buyers begin at the search engines. That is, of all the people who go online planning to buy something or looking for product information, perhaps over 67 percent use a search engine, according to a study in 2005 by iCrossing.

_ The search engines represent a cheap way to reach people. In general, you get more bang for your buck going after free search-engine traffic than almost any other form of advertising or marketing.

按点击付费系统

某些搜素系统提供了按点击付费功能。广告主在这些搜索系统中放置了广告，当用户搜索时，搜索结果就包含了赞助商列表，它们通常在免费结果列表的上方或者右侧。关于按点击付费系统在第17章将会详细介绍。

进一步了解搜索术语

您还需要了解其他的一些跟搜索引擎相关的术语，这些术语在本书的各个地方都有可能碰到：

1，搜索网站：您可以通过这种类型的网站来搜索一些索引目录或者网页目录，或者这两者都可以搜索。（某些情况下，提供元索引搜索的网站允许你同时搜索多个源搜索引擎）Google.com, AOL.com, 以及 EarthLink.com 是搜索网站，DogPile.com 和 Mamma.com是元索引搜索网站。

2，搜索系统：这类组织拥有足够的软件、硬件以及人力资源来索引或者分类各种网站，也就是说，你在搜索网站上搜索的目录和索引是他们创建的。这种区别是很重要的，因为一个搜索网站也许并不拥有自己的搜索索引或者网页目录。例如，Goole 是一个搜索系统，它的结果是从自己创建的索引中查询的，而AOL.com 和EarthLink.com 就不是。实际上，如果你在AOL.com 和EarthLink.com上搜索，你得到的结果是google搜索出来的。Google 和 开放目录系统给上百个搜索网站提供搜索结果。实际上，现在的大多数搜索网站是从其他地方来得到搜索结果，参见图 1-3：

图：1-3：仔细看看，您会发现许多搜索网站产生的搜索结果是其他的搜索系统提供的

3，搜索条件：人们查找信息时在搜索引擎里输入的一个词语，或者几个词语。

4，搜索结果：搜索结果就是你在搜索网站上搜索信息时搜索引擎给你返回的信息（就是跟你的搜索条件相关的结果）。正如刚才解释的，大多数情况下，这些搜索结果不是你正在使用的搜索网站产生的，而是由其他的搜索系统提供的。

5，自然搜索结果：某个web页面在搜索结果页面上出现，一般有两种方式：如果网站主付费了，那么搜索引擎就把他们的网页放在结果页面（按点击付费广告），或者是搜索引擎认为这些页面跟搜索条件很匹配，就把它们从索引中检索出来。这些免费的位置就是总所周知的自然搜索结果，也就是您听说过的有机搜索结果以及算法搜索结果。

6，搜索引擎优化：搜索引擎优化（也就是SEO）是指为了在搜素引擎中取得好的排名而优化网站以及网页。。。当然，这就是本书的主题。

英文原文：

Pay-per-click systems

Some systems provide pay-per-click listings. Advertisers place small ads into the systems, and when users perform their searches, the results contain some of these sponsored listings, typically above and to the right of the free listings. Pay-per-click systems are discussed in more detail in Chapter 17.

Keeping the terms straight

Here are a few additional terms that you will see scattered throughout the book:

_ Search site: This Web site lets you search through some kind of index or directory of Web sites, or perhaps both an index and directory. (In some cases, search sites known as meta indexes allow you to search through multiple indices.) Google.com, AOL.com, and EarthLink.com are all search sites. DogPile.com and Mamma.com are meta-index search sites.

_ Search system: This organization possesses a combination of software, hardware, and people that indexes or categorizes Web sites - they build the index or directory you search through at a search site. The distinction is important, because a search site may not actually own a search index or directory. For instance, Google is a search system - it displays results from the index that it creates for itself - but AOL.com and EarthLink.com aren’t. In fact, if you search at AOL.com or EarthLink. com and search, you actually get Google search results. Google and the Open Directory Project provide search results to hundreds of search sites. In fact, most of the world’s search sites get their search results from elsewhere; see Figure 1-3.

_ Search term: This is the word, or words, that someone types into a search engine when looking for information.

_ Search results: Results are the information returned to you (the results of your search term) when you go to a search site and search for something.

As just explained, in many cases the search results you see don’t come from the search site you’re using, but from some other search system.

_ Natural search results: A Web page can appear on a search-results page two ways: The search engine may place it on the page because the site owner paid to be there (pay-per-click ads), or it may pull the page out of its index because it thinks the page matches the search term well. These free placements are often known as natural search results; you’ll also hear the term organic and sometimes even algorithmic.

_ Search engine optimization (SEO): Search engine optimization (also known as SEO) refers to “optimizing” Web sites and Web pages to rank well in the search engines . . . the subject of this book, of course.

非网络蜘蛛收录

我不太确定该如何命名这个事情，所有我就给它起了个名：非网络蜘蛛收录。有一部分小型网页目录公司，比起Google这些大的公司来说重要性要小一些，不用网络蜘蛛去检查每一个网页的全部内容。相反，这些网页目录收录了每个页面的一些背景资料，例如：标题，页面描述，关键字等。在某些情况下，这些信息是从所收录的所有网页标签中抽取的（在第二章我讲讲标签）。另外的情况是由登录网页目录的访客来提供这些信息。我将在第13章讨论的一些小型网页目录系统就是这样的类型。

英文原文：

Non-spidered indexes

I wasn’t sure what to call these things, so I made up a name: non-spidered indexes. A number of small indexes, less important than major indexes such as Google, don’t use spiders to examine the full contents of each page in the index. Rather, the index contains background information about each page, such as titles, descriptions, and keywords. In some cases, this information comes from the meta tags pulled off the pages in the index. (I tell you about meta tags in Chapter 2.) In other cases, the person who enters the site into the index provides this information. A number of the smaller systems discussed in Chapter 13 are of this type.

网页目录

网页目录是有关网站信息集合的一个分类。它收集了网站的总体信息，并不关注具体的网页信息。

最著名的网页目录是yahoo！目录（dir.yahoocom）和开放目录系统（www.dmoz.org）.(这里提供了一个开放目录系统的信息，Google目录—-dir.google.com—参见图1-2。)

管理网页目录的公司不使用网络蜘蛛或者机器人去下载并索引网站中的网页，对于目录中每一个网站信息，像网站标题和网站描述等，是由网站的所有者提交的。在yahoo!和开放目录系统这两个重要的目录公司中，有专职人员去检查目录系统中收集的所有站点信息，确认网站都提交到正确的分类中并且符合一定的质量要求。对于一些小的目录管理系统来说很少去验证网站的信息，经常以网站所有者提交的为准。

现在让我们来看看Yahoo！网站的搜索结果与Yahoo！目录之间的区别：

1，先登录 www.yahoo.com

2，在搜索框中输入一个词

3，单击搜索按钮

此时列出的网站列表是yahoo！的搜索结果，这个搜索结果是由Google提供的。

4，在页面的顶部有一个目录标签项

您会看到一行字，一般是这样写:分类：鞋类供应商。同时在这一行的下面也会看到相应的搜索结果。

5，单击一下标签项或者链接

您单击后就会离开Yahoo！目录转到相应的网站。（可以通过dir.yahoo.com直接访问Yahoo！目录）。

图1-2 google也有网页目录，不过它自己不创建目录，而是从开放目录系统（ Open Directory Project.）获取信息

译注：前面章节所说的search directories，directory都翻译成了 搜索目录，现在看网页目录似乎更准确一些。以后就把search directories 翻译为网页目录。

搜索引擎和网络目录调查

搜索引擎已经是搜索系统或搜索网站的主要术语，在进一步阅读后续内容之前，您需要了解一些搜索术语之间的区别，这些术语您后面将会碰到。基本上，您需要了解四种搜索术语：

一 搜索目录或搜索引擎

搜索目录或搜索引擎是您将要遇到的主要搜索工具。从根本上讲，搜索引擎这个术语是指某些搜索目录，它拥有大规模的数据库，数据库中包含了许多独立网站的信息。

大型的搜索目录公司拥有数千台电脑，在这些电脑上运行着一种称为网络蜘蛛或者机器人的程序，这些网络蜘蛛从网络上抓取网页并分析网页的内容。这些网络蜘蛛通常并不是把每一个页面中的所有信息或者某一个网站中的所有内容都抓取下来，不过它们还是抓取了大量的信息，并使用复杂的算法（复杂的计算公式）来索引这些信息。Google，如图1-1所示，是世界上最流行的搜索引擎，紧跟其后的是Yahoo！和MSN。

图1-1 Google，世界上最流行的搜索引擎产生的查询结果

附注：索引比赛

2005年晚些时候，Yahoo！(www.yahoo.com) 声称：它的索引量大约是二十亿个页面和两亿张图片以及五千万个音频和视频页面。Google(www.google.com)曾经在它的主页上声明自己实际索引的页面数量—–一度达到15亿个页面，不过Google并不想跟Yahoo！玩“我家东东比你多”的游戏。

英文原文：

Investigating Search Engines and Directories

The term search engine has become the predominant term for search system

or search site, but before reading any further, you need to understand the different types of search, um, thingies, you’re going to run across. Basically, youneed to know about four thingies.

Search indexes or search engines

Search indexes or engines are the predominant type of search tools you’ll run across. Originally, the term search engine referred to some kind of search index, a huge database containing information from individual Web sites.

Large search-index companies own thousands of computers that use software known as spiders or robots (or just plain bots) to grab Web pages and read the information stored in them. These systems don’t always grab all the information on each page or all the pages in a Web site, but they grab a significant amount of information and use complex algorithms — calculations based on complicated formulae — to index that information. Google, shown in Figure 1-1, is the world’s most popular search engine, closely followed by Yahoo! and MSN.

Index envy

Late in 2005, Yahoo! (www.yahoo.com) claimed that its index contained information about almost 20 billion pages, along with almost 2 billion images and 50 million audio and video pages. Google (www.google.com) used to actually state on its home page how many pages it indexed — they reached 15 billion or so at one point — but decided not to play the “mine is bigger than yours” game with Yahoo!

SEO简明教程 第一章 分析搜索引擎概貌（1）

第一部分 搜索引擎基础

搜索引擎优化基本技巧的效果是令人惊奇的，恩，就用最基本的技术。事实上，您通过一点小小地改变就能让您的网站在搜索引擎排名中产生巨大的变化。

这一部分是从基本技巧开始的，我首先从哪些搜索引擎是比较重要的开始讲，您或许听说过很多网站的名字也听说过有数百种搜索引擎，不过您会很高兴地听到，绝大多数的搜索结果是由不超过四个搜索系统来提供的，几乎一半的搜索结果是由一家公司产生。

您将了解到如何又快又简单的修改网站，这将为您的网站解决一系列的搜索优化问题。从另一方面来说，您将发现一些明显（普通）的网站问题，必须解决掉这些问题，然后才有机会让搜索引擎收录您的网站，更不用说好的排名了。本书在这一部分也介绍了一些基本信息，这些信息主要说明了如何建设一个网站，可以让搜索引擎和用户更好地访问，以及您会发现在首要步骤中有一项您必须要做：做一个详尽的关键字分析.

第一章 分析搜索引擎概貌

本章重点：

——了解人们在哪里进行搜索

——理解搜索站点与搜索系统的区别

——把数千家搜索站点缩小到四个搜索系统

——理解搜索引擎是如何工作

——搜集常用工具和基本技巧

您会碰到这样一个问题，您希望人们来访问自己的网站；这是目的，毕竟——–为了把人们带到您的网站购买您的产品，或者享受服务，或者了解您提供的服务，或者其他什么目的您才建立了自己的网站。因此您想从搜索引擎来获取流量—-一个貌似合理的理由，正如您在这一章所了解的那样。但是网络中有着数量众多的搜索引擎！例如目前在网络中知名的几个：google，AOLs，Yahoo！s，以及MSNs，但是，您也许听说过其他的搜索引擎，如：HotBot, Dogpile, Ask Jeeves, Netscape, EarthLink, LookSmart . . .，甚至Amazon几乎在每个页面上都提供了搜索服务。还有Lycos和InfoSpace公司， Teoma和WiseNut ， Mamma.com和WebCrawler。一些网页的顶部，您应该看到过一些如此宣传的广告：只需49.95美元（或者19.95美元，或者99.95美元，或者广告投放人搞的其他任何数额），您就能让您的网站在数以百计甚至数以千计的搜索引擎中出现。您也许使用过其中一些服务，唯一的结局就是：承诺的洪水般流量来了又消失了。恩，我这里有点好消息，您可以忘掉我几乎所有刚才提到的名字，至少是看完这一章以后。本章节的重点是粗略了解网络中数以千计的搜索引擎，然后把关注的数量缩小到一小群搜索系统。（什么是搜索网站？什么是搜索系统？不要着急，我稍后讲讲他们的区别）如果你确实着急，可以跳到“人们在哪里进行搜索”这一节，就在这一章的结尾部分，列出了您需要关心的以及可以忽略的搜索系统详细资料。不过我发现，当我把这些资料告诉一些人的时候，他们看着我以为我发疯了，因为有一部分他们知道的知名网站没有出现在这个列表中。本章就讲讲为什么会这样。

英文原文：

Part I Search Engine Basics

The basics of search engine optimization are surprisingly,um, basic. In fact, you may be able to make small changes to your Web site that make a huge difference in your site’s ranking in the search results.

This part starts with the basics. I begin by explaining which search engines are important. You may have heard the names of dozens of sites and heard that, in fact, hundreds of search engines exist. You’ll be happy to hear that the vast majority of search results are provided by no more than four systems, and half of all the results come from a single company.

You also discover how to make some quick and easy changes to your Web site that may fix serious search engine problems for you. On the other hand, you may discover a significant (and common) problem in your site that must be resolved before you have any chance of getting into the search engines at all, let alone ranking well. This part of the book also includes basic information on how to create a Web site that works well for both visitors and search engines, and you find out about one of the most important first steps you can take: carrying out a detailed keyword analysis.

Chapter 1

Surveying the SearchEngine Landscape

In This Chapter

_ Discovering where people search

_ Understanding the difference between search sites and search systems

_ Distilling thousands of search sites down to four search systems

_ Understanding how search engines work

_ Gathering tools and basic knowledge

You’ve got a problem. You want people to visit your Web site; that’s the purpose, after all — to bring people to your site to buy your product, or learn about service, or hear about the cause you support, or for whatever other purpose you’ve built the site. So you’ve decided you need to get traffic from the search engines — not an unreasonable conclusion, as you find out in this chapter. But there are so many search engines! You have the obvious ones — the Googles, AOLs, Yahoo!s, and MSNs of the world — but you’ve probably also heard of others: HotBot, Dogpile, Ask Jeeves, Netscape, EarthLink, LookSmart . . . even Amazon provides a Web search on almost every page. There’s Lycos and InfoSpace, Teoma and WiseNut, Mamma.com and WebCrawler. To top it all off, you’ve seen advertising asserting that, for only $49.95 (or $19.95, or $99.95, or whatever sum seems to make sense to the advertiser), you too can have your Web site listed in hundreds, nay, thousands of search engines. You may have even used some of these services, only to discover that the flood of traffic you were promised turns up missing. Well, I’ve got some good news. You can forget almost all the names I just listed — well, at least you can after you’ve read this chapter. The point of this chapter is to take a complicated landscape of thousands of search sites and whittle it down into the small group of search systems that really matter. (Search sites? Search systems? Don’t worry, I explain the distinction in a moment.)If you really want to, you can jump to “Where Do People Search,” near the end of the chapter, to the list of search systems you need to worry about and ignore the details. But I’ve found that, when I give this list to someone, he or she looks at me like I’m crazy because they know that some popular search sites aren’t on the list. This chapter explains why.

英文原文：

Part I: Search Engine Basics

In this part, I provide, yep, the basics — the foundation on which you can build your search-engine-optimization skills. Which search engines are important, for instance? In fact, what is a search engine? And what’s a search directory?

And why am I using the term search system? In this part, you find out

the basics of sensible site creation, discover how to pick the keywords that people are using to find your business, and discover how to do a few quick fixes to your site.

Part II: Building Search-Engine-Friendly Sites

Do you have any idea how many sites are invisible to the search engines? Or that, if they’re not invisible, are built such that search engines won’t see the information they need to index the site in the way the site owners would like?

Well, I don’t know an exact number, but I do know it’s most sites. If you read Part II, you will be way ahead of the vast majority of site owners and managers.

You discover how to create techniques that search engines like and avoid the ones they hate. You also find out about tricks that some people use — and the dangers involved.

Part III: Adding Your Site to the Indexes and Directories

After you’ve created your Web site and ensured that the search engines can read the pages, somehow you have to get the search systems — the engines and directories — to include your site. That’s hard if you don’t know what you’re doing. In this part, you find out which search systems are important, how to register, and how to find other search engines and directories that are important to your site. You also find out why registering sometimes doesn’t work, and what to do about it.

Part IV: After You’ve Submitted Your Site

Your work isn’t over yet. In this part of the book, you find out why links to your site are so important and how to get other sites to link to you. You discover the shopping directories, such as Froogle and Shopping.com. I also explain the multibillion-dollar search engine advertising business. You find out how to work with the hugely popular Google AdWords and Yahoo! Search Marketing pay-per-click programs . . . and how to buy cheaper clicks. You also discover paid placement and other forms of advertising.

Part V: The Part of Tens

All For Dummies books have the Part of Tens. In this part, you find ten ways to keep up to date with the search-engine business. You also find out about ten common mistakes that make Web sites invisible to search engines, and ten services and tools that will be useful in your search engine campaign.

Appendix，

Don’t forget to check out the appendix, where you find information on copyright laws.

SEO简明教程—章节介绍

本书的章节安排

像很多不错的参考工具书那样，本书是按照 “实际需要”的阅读顺序来安排章节结构的。本书分成了几个部分：基础部分，建设搜索引擎友好的网站，把网站提交到搜索引擎，搜索引擎收录网站后要做的工作，搜索引擎广告，十大建议。。。等等，如果您只想了解如何寻找一些网站，他们能够链接到您的站点，那么可以看看15章。如果您想了解获取外链背后的一些规则，那么可以看看14章。如果您现在想了解关键字对一个网站到底有多重要，那么第5章就是为您准备的。

然而，搜索引擎优化是一个相当复杂的工作，并且本书的所有知识是相互关联的。当然，您能够把您的网站提交到搜索引擎，但是如果您的网页没有针对搜索引擎进行优化，那么，这也许会浪费您的时间！您也许编写了一些搜索引擎可以阅读的网页，但是如果您没有选择正确的关键字，那也是在浪费时间。所以，我建议您完整的阅读本书；它会让您的网页在搜索引擎中的排名产生巨大变化。

How This Book Is Organized

Like all good reference tools, this book is designed to be read “as needed.”

It’s divided into several parts: the basics, building search-engine-friendly Web sites, getting your site into the search engines, what to do after your site is indexed by the search engines, search engine advertising, and the Part of Tens. So if you just want to know how to find sites that will link to your Web site, read Chapter 15. If you need to understand the principles behind getting links to your site, read Chapter 14. If all you need today is to figure out what keywords are important to your site, Chapter 5 is for you.

However, search engine optimization is a pretty complex subject, and all the topics covered in this book are interrelated. Sure, you can register your site with the search engines, but if your pages aren’t optimized for the search engines, you may be wasting your time! You can create pages the search engines can read, but if you don’t pick the right keywords, it’s a total waste of time. So I recommend that you read everything in this book; it will make a huge difference in how well your pages are ranked in the search engines.
