rel=nofollow 子域
我有一个用于广告的子域。它安装了 openx 来提供广告服务。我如何确保子域中的所有内容都像添加 rel=nofollow 一样处理,因为我不希望 Google 和其他搜索引擎认为我们认为这些广告值得关注。
I have a subdomain that i use for advertisements. It has openx installed to serve the ads. How can I ensure that everything from the subdomain gets treated like adding rel=nofollow as I don't want Google and other search engines to think that we think the ads are worth following.
