Have you ever looked at a web site that wasn't quite right? Perhaps the content didn't fit properly in a frame or the text was all skewed across the page? Or even worse, you get error messages for parts of a site that just won't load in your browser, yet your colleagues can see it perfectly?

你是否浏览过外观糟糕的页面呢？有时框架内容安排不恰当，有时页面文本歪斜，甚至有时浏览器不能下载某些内容，但你同事的电脑中，网站外观却很精美，有没有遇到这种情况呢？

Welcome to the world of browser incompatibility. This happens when a site is designed for a particular type of browser, (ie Microsoft's Internet Explorer or Netscape's Navigator) or even a specific version of that browser, without any consideration for persons viewing the site using different browsers or older versions. You see, a very flashy corporate site that might look fantastic in version 4.0 or 5.0 of Internet Explorer can end up looking like a child's finger painting in Navigator 3.0 and vice versa.

为什么介绍兼容性呢？网站有时专为某种浏览器设计（比如IE或者Netscape公司的Navigator），或者专为浏览器某种版本设计，并没有考虑其它浏览器用户。例如，在IE4.0或者IE5.0中外观精美的网站，在Navigator3.0中外观就很糟糕，反过来也一样。

Which is why backwards-compatibility testing by web development firms is so important prior to site launch. Unfortunately, the tedious nature of testing and work involved in making the site compatible with all browsers often means web designers take short cuts - either avoiding testing completely or satisfying themselves with making the site compatible with only the latest browsers. The company commissioning the site is usually left unaware that their site is not backwards-compatible and that some of their site visitors are forming a negative opinion of their site and consequently, their company. When the competition is only one click away, image is EVERYTHING.

在网站运行之前，网站开发公司应改进行向后兼容测试。然而，由于测试工作很枯燥，很多网站设计者不重视这一步，或者没有测试，或者只在最新的浏览器中测试。许多公司通常也没有注意网站兼容性测试，致使网站访问者对网站以及公司产生了消极态度。有时候，形象决定一切。

Another short cut development firms sometimes take is with search engine compatibility. The creation of site META tags in the HTML code and the inclusion of key search terms relating to site content in the body text can make a world of difference to how a web site ranks in search engines. Known as site optimization, this value-added service takes a little more time within the site build, but can ensure the client site receives the maximum exposure in search engines and consequently, much more site traffic. Some web development firms don't even bother to register the site with major search engines, let alone know how to optimize the site for better search engine performance.

网站开发公司还应该进行搜索引擎兼容性的测试。HTML编码中META标签的创建，以及与网站内容相关的搜索术语会影响网站在搜索引擎中的排名。网站优化可以保证网站的排名，增加网站访问量。有些网站开发公司甚至没有在搜索引擎中注册网站，更不用说网站优化了。

There are companies I've heard of that have had a web site for a number of years but have no idea how it is performing, why persons are complaining about errors or why it isn't receiving traffic. They've been ripped off by sub-standard web developers who either don't know, or don't care enough about web compatibility to do an adequate job.

我曾经听说过，有些公司建立网站多年了，但并不了解网站如何运行，人们为什么抱怨网站错误，网站访问量为什么这么少，等等类似的问题。正是这些不了解、或者不关心网站兼容性的开发者，毁掉了公司网站。

Fortunately, this lack of compatibility can be reversed. Even sites that have been launched some time ago can be analysed, tested and re-designed for browser compatibility as well as optimized for search engines. What's more, site performance can now be measured by sophisticated site traffic measurement and search engine ranking software. Comprehensive site logs (or visitor statistics) can give you a good indication of how your site is performing over a long period.

然而幸运的是，网站兼容性可以改变。即使是对已运行一段时间的网站，我们仍然可以分析、检测、重塑网站，增强网站兼容性。另外，我们可以利用测量网站访问量、检验网站搜索引擎排名的软件，了解网站运行情况。可理解的网站记录（或者访问者统计）可以显示网站某段时间的运行情况。

These statistics are an extremely useful management/analysis tool because it enables site stakeholders to interpret visitor trends and identify areas needing improvement. It is particularly useful for justifying/curbing Internet expenditure and planning for future site expansion.

这些统计资料是很有用的管理、分析工具，因为它可以帮助网站设计者根据访问趋势，改善网站兼容性，并且从长远来说，可以控制网站成本，有利于网站的扩大。

There will always be sub-standard web development firms that try to cut corners with web site production. But that doesn't mean you have to settle for second best. Armed with the knowledge of what compatibility standards your site should meet, you can insist your site is tested and up to scratch well before launch.

总有些不合格的网站开发公司，在进行网站建设时，省略某些必要步骤，但这并不意味着你也要这样做。网站必须符合兼容性标准，这样才能为网站运行做好准备。
