大二级分类产品页权重低,不收录怎么办?
2022-07-07 23:05:00 【华为云】
典型树形结构首页链接到一级分类,一级分类页面再列出二级分类,这样,只要二级分类数目相差不太悬殊,权重值在二级分类页面上是大致平均分配的。
不过有的时候某些二级分类下的产品数远远多于其他小一些的二级分类,甚至产品太多的二级分类下还可以再列出三级分类。
平均分配权重的结果就是,小分类充分收录,产品数量大的大分类有很多产品页面因为权重稀释无法收录。
要解决这个问题,思路就是提高大二级分类页面的权重,使它能带动的产品页面增多。
现在很多网站导航系统采用CSS下拉菜单方式,鼠标放在一级分类链接上时,菜单向右或向下拉出一部分二级分类页面。
当由于空间有限和用户体验因素不能显示所有二级分类时,选择显示哪些二级分类就是个学问。
显然不能按拼音或字母顺序把排列在前的5个或10个放入主导航。
一种方法是从用户体验出发,先选择热门二级分类。
再一种方法是选择包含产品数量最多、需要权重支持才能充分收录的二级分类。
这两者有时候是重合的,热门分类也是产品最多的分类,有时候不尽然。
这个原则同样适用于多层分类。如果网站有三层分类页面,应该计算出每个三级分类下有多少个产品,想办法把这些大三级分类页面放在首页上,如果可能,放在尽量多的导航中。
