做企业官网这事儿,我见过太多老板交智商税了。真不是吓唬你,随便找个外包,要么做出来的页面丑得像上世纪的产物,要么速度快得让你怀疑人生,更别提什么SEO优化了,根本没人搜得到。今天我就把话撂这儿,想在北京找靠谱的北京网站制建设公司,你得把心放肚子里,按我说的这几步走,至少能避开80%的坑。
首先,别一上来就问“多少钱”,这问题太外行。你得先想清楚你要什么。是只要个面子工程,还是真想要个能获客的工具?很多老板觉得网站就是个电子名片,随便弄弄就行。错!大错特错!现在的用户,手机点一下,加载超过3秒直接关页面。所以,第一点,看案例。别听他们吹什么“服务过世界500强”,那都是扯淡。你就让他们拿最近半年的、和你行业类似的案例给你看。打开他们的网站,用手机测速,看看排版乱不乱,看看有没有那种满屏乱飞的弹窗广告。如果有,直接Pass,这种公司审美和技术都在线不了。
第二步,聊技术细节。这时候别装懂,就问两个核心问题:一是源码是否交付,二是后台是否易用。有些黑心公司,做完网站把源码扣下,以后你想换个公司维护,还得求着他们,甚至被勒索。一定要在合同里写明,项目验收后,所有源码、数据库、设计素材必须全部移交给你。至于后台,最好要求用成熟的CMS系统,比如WordPress或者织梦(虽然织梦有点老,但胜在稳定),别搞什么 proprietary
