动网论坛采用javascript+模版的方式显示页面，服务器将没有深加工的数据和js代码一起发送到客户端解析，减轻了服务器负担，但是搜索引擎一般不会解析javascript代码的，不过动网论坛的主要页面都有判断浏览器类型，如果是搜索引擎，自动跳转到专门为浏览器显示的页面，但是这些页面做得不是太好，下面是我修改的结果：
昨天我把论坛的meta标签的description部分去掉，Google发现这个标签后就会忽略下面的内容，直接区标签中的内容。
修改index.asp:
将函数Sub Show_Index_Footer()中的
Dim BrowserType
If BrowserType.IsSearch Then Response.redirect "indexNew.asp" |
提升到index.asp的前面，让页面一检测到是搜索引擎就跳转到优化后的页面，原来那样子的结果是google仅仅抓取了Show_Index_Footer()中的信息，前面的都给忽略了。
修改indexnew.asp
将Dvbbs.head()改为Dvbbs.head()
注释掉
Dvbbs.ActiveOnline()
Show_Index_Top
Show_Index_Footer
Response.Write Replace(template.html(9),"{$Getlink}",Getlink())
If Dvbbs.Forum_setting(29)="1" Then Call birthuser()
Dvbbs.Footer()
Response.Write Dvbbs.value
Response.Write template.html(8)(1) |
这样子跳转后的首页显示的就相对比较简单了，但是代码还是有些冗余，如果想再精简些，就不要用dvbbs的模版了，直接用asp生成静态页面，能去掉的都去掉。
同样修改list_show.asp
将Dvbbs.head()改为Dvbbs.head()
注释掉
News
Board_Online
Show_List_Footer
Dvbbs.ActiveOnline()
Dvbbs.Footer() |
再修改printpage.asp
如果你的论坛需要注册用户才能浏览，而你又要搜索引擎能够抓取信息的话，把If Dvbbs.GroupSetting(2)="0" Then Dvbbs.AddErrcode(31)这行注释掉。
其他的没什么好改的，这个页面的模版已经做得非常精简了，你可以试着修改page_postjob模版来增加些其他的连接。
下面作一个更有实际效果的索引页面，很多不错的php论坛都有这样的页面，效果很好：
新建一个目录，随便什么，然后在里面建立一个index.asp文件，这个文件的代码我直接用了动网论坛的newtopic.asp，把里面的js去掉就行了：
<!--#include file="../conn.asp"-->
<!--#Include File="../inc/Dv_ClsMain.asp"-->
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />

然后再去修改indexnew.asp，加上这个页面的索引就行了。
剩下的大家去挖掘吧~哈哈
