想要做好seo，必须专注于一些细节点，包括到底多长的URL对于搜索引擎才是最友好的。
在google站长论坛中，看到一个关于到底多少长度的URL才是最合适的讨论。
google的John Mueller表示，并没有明确的长度限制，但是通过google的声明我们可以知道url的长度要少于2000字节。
John Mueller的原话:
As far as I know, there's no theoretical length limit, but we recommend keeping URLs shorter than 2000 characters to keep things manageable.
如果你的URL长度大于2000，它看起来会像下面这种样子：

不管是对搜索引擎还是用户体验都是很不好的。
