TechCrunch, for example, does not use the Meta-Keywords tag on their site (something I have seen a lot of the top sites doing).
举例来说，不使用元标签关键词在其网站上(我看到很多顶级站点做)。
You can also use the long lost "Keywords" meta tag for this purpose, for those crawlers that still look at it.
你也可以使用一些关键词样式的元标签来达到同样的目的，针对那些依然还看这些的爬虫。
The service also allows users to "tag" bookmarks with keywords, and view the most popular bookmarks at any given time.
该服务还允许用户用关键字“标记”书签，随时查看最受欢迎的书签。
