网站维护是为了让您的网站能够长期稳定地运行在Internet上，及时地调整和更新您的网站内容，在瞬息万变的信息社会中抓住更多的网络商机
1服务器及相关软硬件的维护，对可能出现的问题进行评估，制定响应时间；
计算机硬件在使用中常会出现一些问题，同样，网络设备也同样影响企业网站的工作效率，网络设备管理属于技术操作，非专业人员的误操作有可能导致整个企业网站瘫痪。 没有任何操作系统是绝对安全的。维护操作系统的安全必须不断的留意相关网站，及时的为系统安装升级包或者打上补丁
2数据库维护，有效地利用数据是网站维护的重要内容，因此数据库的维护要受到重视
3内容的更新、调整
建站容易维护难。对于网站来说，只有不断地更新内容，才能保证网站的生命力，否则网站不仅不能起到应有的作用，反而会对企业自身形象造成不良影响。如何快捷方便地更新网页，提高更新效率，是很多网站面临的难题。现在网页制作工具不少，但为了更新信息而日复一日地编辑网页，对信息维护人员来说，疲于应付是普遍存在的问题。 内容更新是网站维护过程中的一个瓶颈。网站的建设单位可以考虑从以下五个方面入手，使网站能长期顺利地运转。 1、在网站建设初期，就要对后续维护给予足够的重视，要保证网站后续维护所需资金和人力。很多单位是以外包项目的方式建设网站的，建设时很舍得投入资金。可是网站发布后，维护力度不够，信息更新工作迟迟跟不上。网站建成之时，便是网站死亡的开始。 2、要从管理制度上保证信息渠道的通畅和信息发布流程的合理性。网站上各栏目的信息往往来源于多个业务部门，要进行统筹考虑，确立一套从信息收集、信息审查到信息发布的良性运转的管理制度。既要考虑信息的准确性和安全性，又要保证信息更新的及时性。要解决好这个问题，领导的重视是前提3.网上还有一些人员专门为企业站提供维护支持,例如: 在百度里面搜索"中国制造".这样类型的网。http://djt.qq.com/bbs/thread-250223-1-1.html

http://djt.qq.com/bbs/thread-223491-1-1.html4、对经常变更的信息，尽量用结构化的方式（如建立数据库、规范存放路径）管理起来，以避免数据杂乱无章的现象。如果采用基于数据库的动态网页方案，则在网站开发过程中，不但要保证信息浏览环境的方便性，还要保证信息维护环境的方便性。 5、要选择合适的网页更新工具。信息收集起来后，如何"写到"网页上去，采用不同的方法，效率也会大大不同。比如使用Notepad直接编辑HTML文档与用Dreamweaver等可视化工具相比，后者的效率自然高得多。倘若既想把信息放到网页上，又想把信息保存起来以备以后再用，那么采用能够把网页更新和数据库管理结合起来的工具效率会更高
4制定相关网站维护的规定，将网站维护制度化、规范化
5做好网站安全管理，防范黑客入侵网站，检查网站各个功能，链接是否有错。
