淘宝网上添加商品到购物车时，弹出窗口显示购物车里面的状态。

 
淘宝网购物车

不结ꩵ账，继续购物的时候，淘宝不给任何购物车状态提示，除非你点击顶部购物车链接或者再次添加宝贝到购物车，才能知道购物车꧑里面到底有多少东西、要花多少钱。

当当网上在商品页面点击购买后直接进入购物车，不结账，继续浏览，会发现在当当网顶部有购物车状态提示有多少个商品在购物车里了，但是不告诉你总共多少钱。
 

当当网购物车带着走

altrec上添加商品到购物车的时候，顶部动态打开窗口给出细节提示。

 
altrec的购物车提示

关闭后缩小为简单的购物车状态提示，信息包括物品数目、总金额。继续浏览购物时，购物车状态提示一直跟随，并且一直提醒免运费。
 

altrec的购物车站台跟随

当当网与altrec.com的这种跟着用户走的购物车叫做Perpetual shopping carts，（不知道学名叫什么，我把他叫做随身购物车，或者贴身购物车？）根据Marketing Sherpa的调查64%的在线零售商认为这种购物车对于提高转化很有帮助，而且altrec.com这种高级的购物车状态跟随比当当的这种简洁版🍌效果要好。

Perpetual shopping carts: these come in a variety of ‘flavors’ and not all are created eq☂ual. The data is limited, but it appears that carts which ‘ride along’ with the shopper as they move through the site have a significant impact on conversion. This varies by the type of perpetual cart. Some simply show a dollar total that changes dynamically with purchases, while others may show some or all of the following; product details, thumbnail images, estimated shipping costs and recommended accessories/related products. While 38% of our sample employ some version of the perpetual cart, the vast majority fall into the simpler category, which has a positive but lesser 🔯effect than the enhanced versions.

同样在M𒊎arketingSherpa的2009 Ecommerce Benchmark Report里面，分析师和营销人员都认为Perpetual shopping cart对于减低购物车放弃率有很好的𓂃帮助。

Shopping-Cart Abandonment

电子商务网站要提高转化率，流程里外优化都重要。谁对这方面有研究的？欢迎分享、探讨下。
