discuz x3.1 <meta name="description" content="论坛 " />
 

管理员进入后台-->全局 » seo设置-->论坛
就可以进行具体设置了.

当时这样设置,在meta tag标题中会出现Powered by Discuz!. 如何删除Powered by Discuz!呢?

ftp进入template/default/common, 打开header_common.htm

修改:
<title><!--{if !empty($navtitle)}-->$navtitle - <!--{/if}--><!--{if empty($nobbname)}--> $_G['setting']['bbname'] - <!--{/if}--> Powered by Discuz!</title>
为:
<title><!--{if !empty($navtitle)}-->$navtitle - <!--{/if}--><!--{if empty($nobbname)}--> $_G['setting']['bbname']<!--{/if}--></title>
