This strategy is known as reciprocal linking (two sites that link to each other), and is ignored by Google.
这个战略被称为互惠性链接(两个站点互相链接)，它被Google所无视。
Reciprocal links less valuable than one-way, because it tells Google that you’ve arranged it, rather than earned the link through creating great content
相互链接的价值不如单向链接，因为Google会检测出前者是经过认为安排的，而不是通过网站的高质量内容产生的指向该网站的链接
A better approach would be to approach existing group owners and ask to set up a reciprocal link exchange between your groups, just as you would on the open web.
较好的方法是直接联系那些群组的创建者，群组之间互相交换个链接，就像网站交换链接一样。

如果被接受，就会创建一个相应的“confirmed”链接。
