www.seozac.com和seozac.com哪个对SEO更有优势？

赵振东提问于 3年之前

www. seozac.com 和 seozac.com 如何解析?seo过程中用哪个域名做更有优势？

1 个回答

Zac 管理员回答于 3年之前

技术上说，www. seozac.com是 seozac.com的一个子域名，但互联网历史造成大多数网民觉得www. seozac.com才是最常用、最顺眼的网址，所以现在大部分网站也还是以带3W的URL为默认网址。

这两个在SEO方面是一样的，不存在哪一个更有优势。选哪个都行。近年一些技术型网站喜欢不带3W的，看着比较酷吧。

选定一个为默认网址，为了避免网站规范化问题，另一个要做些处理：要么直接不解析（新站可以直接这样做），要么解析，但做301转向到默认版本网址。

Zac, 其实你应该把SEOZAC 和zacseo 都指向你现在的博客的。

Zac 管理员回复于 3年之前

zacseo.com？不是我的域名啊。

John 回复于 3年之前

是啊，我开始看你的网站的时候，老是记不清域名， seozac zacseo的输入，现在zacseo是菠菜网站了 ??

为什么新站上线没多久就被降权？

威海seo问答威海seo问答

有可能是网站没有按照搜索引擎规定的标准建站，新站使用了不当的SEO技术，在不久的未来将会被搜索引擎认定为违规站点并将其出现在搜索结果中的机会被降低。由此可见，网站上线不久就被降权，有可能是网站违规技术导致，建议应尽快及时检查调整网站，让网站更符合规定来免受搜索引擎降权的状况发生.

阿里云CDN设置80端口还是443端口

威海seo问答威海CDN与seo

建议使用443端口，因为443端口是HTTPS协议的默认端口，可以提供更加安全的数据传输。同时，使用443端口也可以避免某些网络环境中80端口被封锁的问题。如果需要同时支持HTTP和HTTPS协议，可以将80端口重定向到443端口。

网站启用CDN，百度收录时间显示为1天前

关广辉博客提问于 3年之前网站启用CDN、在百度site网站收录，收录时间显示为1天前。内容都是原创，文章发布时间和收录文章的快照时间，有的相差几十秒，有的相差几分钟，有的相差几小时。但是所有的site展示都是显示1天前，而不是几小时或者多少分钟。请问下Zac老师，这情况是否和CDN缓存设置有问题，CDN用腾讯的。4 个回答Zac 管理员回答于 3年之前你说的情况和CDN没什么关系。搜索引
