是这样的,之前接了一个金主的单子,他想在淘宝开个小鱼零食的网店,想对目前这个市场上的商品做一些分析,本来手动去做统计和分析也是可以的,这些信息都是对外展示的,只是手动比较麻烦,所以想托我去帮个忙。
具体的要求如下:
1.在淘宝搜索“小鱼零食”,想知道前10页搜索结果的所有商品的销量和金额,按照他划定好的价格区间来统计数量,给我划分了如下的一张价格区间表:
2.这10页搜索结果中,商家都是分布在全国的哪些位置?
3.这10页的商品下面,用户评论最多的是什么?
4.从这些搜索结果中,找出销量最多的10家店铺名字和店铺链接。
从这些要求来看,其实这些需求也不难实现,我们先来看一下项目的效果。
获取到数据之后做了下分析,最终做成了柱状图,鼠标移动可以看出具体的商品数量。
在10~30元之间的商品最多,越往后越少,看来大多数的产品都是定位为低端市场。
然后我们再来看一下全国商家的分布情况:
可以看出,商家分布大多都是在沿海和长江中下游附近,其中以沿海地区最为密集。
然后再来看一下用户都在商品下面评论了一些什么:
字最大的就表示出现次数最多,口感味道、包装品质、商品分量和保质期是用户评价最多的几个方面,那么在产品包装的时候可以从这几个方面去做针对性阐述,解决大多数人比较关心的问题。
最后就是销量前10的店铺和链接了。
在拿到数据并做了分析之后,我也在想,如果这个东西是我来做的话,我能不能看出来什么东西?或许可以从价格上找到切入点,或许可以从产品地理位置打个差异化,又或许可以以用户为中心,由外而内地做营销。
越往深想,越觉得有门道,算了,对于小鱼零食这一块我是外行,不多想了。
由于源码分了几个源文件,还是比较长的,所以这里就不跟大家一一讲解了,懂爬虫的人看几遍就看懂了,不懂爬虫的说再多也是云里雾里,等以后学会了爬虫再来看就懂了。

通过上面的代码,我们能获取到想要获取的数据,然后再Bar和Geo进行柱状图和地理位置分布展示,这两块大家可以去摸索一下。
