【网站百科】更换域名和服务器对网站优化的影响
网站经过一段时间的运营，中途可能由于各种原因需要更换域名或者服务器，从搜索引擎优化的角度来说，网站一旦上线最好不要更换域名和服务器，对已经优化上的关键词会有一定的影响，具体有什么影响？为什么会有这些影响？怎么去排除这些影响？今天我们就来了解一下。
网站抓取率下降
如果网站更换了域名，那么搜索引擎就会对域名重新审核，一切都需要从零开始，就和新网站上线一样，域名要经过重新的评估才会进入收录排名阶段，更换服务器影响要比更换域名影响要小一些，服务器只是更换了IP，只要网站内容和结构没有打的改版影响都不会很大。
网站关键词波动
更换域名服务器，最大的影响就是关键词的排名的波动，可能在此之前网站关键词已经在首页有了排名，一旦更换了域名或服务器，搜索引擎要对网站进行重新的评估，这时候排在首页的关键词就会有波动。
网站收录下降
更换域名服务器影响的是网站的整体，收录肯定会有一定的波动，甚至还有可能急剧的下降，这些情况都是可能存在的，毕竟搜索引擎需要对网站重新进行评估！
如何降低影响？
推荐采用SAAS云建站方式。通过基于SAAS云建站的服务模式，实现服务器的永不停机（云服务的稳定性比单体服务器要高很多）。从源头上解决网站对服务器的依赖问题。
