区分访客国家有什么用?

区分网站功能
这个博客有翻译文章的功能, 这是为了方便海外访客阅读文章, 但对中国人显得十分多余. 所以我通过 IP 判断国家, 对中国大陆地区屏蔽翻译功能.

区分展示广告
我在网站侧边栏放有广告, 很多中文广告对海外流量来说毫无意义, 所以我进行区分展示. 中国大陆地区在侧边栏最下方看到的是拿福能的广告, 而其他地区看到的是 Google 的广告.?hostucan?是我的一个广告主, 有英文网站, 也有中文网站, 所以我可以向他提供区分展示服务, 免得浪费流量.

屏蔽布点服务
海外有很多好的服务平台, 在网站上布点即可采集数据和分享文章. 但很不幸, 因为某些原因, 他们在国内展示效果并不好, 不但没有起到应有效果, 还让页面加载时间变长. 可以对大陆访客屏蔽这些布点.
