有不少的网站为导航链接加上了特效，如点击某个项目会展开下层链接等。这些效果一般通过Java script实现，视觉上非常新颖，但在"蜘蛛"程序的眼里则没那么诱人，相反它无法解读这种链接。为了让搜索引擎顺利检索到网页，建议还是牺牲掉一些花哨的东西。
Many websites have added special effects to navigation links, such as clicking on an item to expand the underlying links. These effects are usually achieved through Java script, which looks very novel visually, but in the eyes of "spider" programs, they are not as tempting, and on the contrary, they cannot interpret such links. In order for search engines to successfully retrieve web pages, it is recommended to sacrifice some fancy things.

五、FLASH
5、 FLASH
虽然FLASH制作的网页视觉效果较好，但搜索引擎对此却不太感冒，个案表明这一类的网站很难被百度搜索引擎索引。明智的做法是提供FLASH和非FLASH网页两种选择，这样即增加了网页的观赏性，又照顾到了搜索引擎的情绪。
Although the visual effects of the web pages created by FLASH are good, search engines are not very interested in this. Cases have shown that such websites are difficult to index by Baidu search engines. It is wise to offer two options: FLASH and non FLASH web pages, which not only increases the viewing experience of the webpage but also takes into account the emotions of search engines.
六、动态网页（DynamicPages）
6、 Dynamic Pages
任何地址中带“?”号、“&”号（及其他类似符号）的网页都会把“蜘蛛”程序挡在门外。这些网页通常由 CGI、PHP、ASP、JSP等程序产生，技术上较先进，但不适合搜索引擎的“蜘蛛”程序。
Any webpage with "?", "&" (and other similar symbols) in the address will block the "spider" program from the door. These web pages are usually generated by programs such as CGI, PHP, ASP, JSP, etc., which are technically advanced but not suitable for search engine "spider" programs.
