做了15年建站，我见过太多老板因为不懂行，花几万块买个“垃圾”网站，最后只能扔在那吃灰。今天不整那些虚头巴脑的理论，咱们就聊聊试述网站建设的流程里，到底哪些坑能让人倾家荡产，哪些钱该花，哪些钱省了能活命。
很多客户一上来就问：“做个官网多少钱？”我一般直接回他：“看你想要个展示牌，还是要个销售员。”试述网站建设的流程，第一步从来不是写代码，而是定需求。我有个做五金的朋友，非要搞个像苹果官网那样炫酷的3D效果，结果预算只有5000块。最后做出来的页面加载慢得像蜗牛，客户还没看完就关了。这就是典型的贪多嚼不烂。真正的流程，第一步是梳理业务逻辑。你要网站解决什么问题？是卖货？还是品牌展示？如果是卖货，购物车流程顺不顺比页面漂不漂亮重要一万倍。
第二步，选技术栈。这里有个大坑，很多公司推荐你用某种“ proprietary ” proprietary proprietary proprietary proprietary proprietary proprietary proprietary proprietary proprietary proprietary proprietary proprietary proprietary
