如何让像谷歌这样的搜索引擎可以访问Flex RIA内容？

Question

如何让Google可以访问Flex RIA应用程序的内容,以便Google可以为内容编制索引并显示指向Flex RIA中正确项目的链接.考虑一个在Flex中创建的在线商店,其中所提供的商品应由Google编制索引.然后Google上的链接应该在RIA中打开相应的产品.

Currently the best technique for making an RIA indexable by search engines is called progressive enhancement (or graceful degradation, depending on which way you see it). Basically you create a simple HTML version of the application using the same data as the application loads. This version should be dynamically generated by some kind of backend server technology. This HTML version can be indexed by Google, but each page also contains a check that determines if the visitor is capable of viewing the rich version, and if so replaces the HTML content with the Flash, Flex or Silverlight application, preferably in such a way that the application starts in a state where it shows the same data as the current page. "Replaces" can mean that it just embeds the application on top of the HTML content, or that it redirects the user to a page that embeds it. The former solution is preferable, because the latter can be considered cloaking.

保持商店的HTML和RIA版本同步的一种方法是决定URL方案并确保RIA使用某种深度链接技术.如果访问者通过搜索引擎到达特定项目,则说/items/345RIA中相应的伪URL应该相同,这样您就可以将RIA嵌入页面顶部并将该URL设置为参数以进行RIA加载后立即显示相同的页面.

今年夏天,谷歌和雅虎!宣布他们将开始使用Flash Player的自定义版本来索引基于Flash的应用程序,方法是"以与人相同的方式"对其进行探索.现在,两个月后仍然没有证据表明这确实发生了.Ryan Stweart不得不取消他的Flex SEO竞赛,因为很明显没人能赢.问题似乎是该事件尽管该技术可能非常有效(尽管我持怀疑态度),但自定义Flash Player需要某种网络接口才能加载任何引用的资源,如XML数据,其他SWF等. ,目前尚未由Google实施.这意味着对于一个动态加载所有数据的应用程序,比如说,我能想到的一切,Googlebot实际上看不到任何相关内容.雅虎 完全忽略基于SWF的内容.
