#3: Keywords in URLs: still a good thing

3.关键字体现在URL中

#4: Multiple URLs serving the same content? Canonicalize 'em!

4.多个页面提供相同的内容？规范化他们！(有点难理解)

#5: Exclude dynamic parameters when possible

5.尽量排除动态参数（个人理解和第二点类似）

#6: Shorter > longer

6.短链接更可读。

#7: Match URLs to titles most of the time (when it makes sense)

7.URL和页面的title标签尽量保持一致。

#8: Including stop words isn't necessary

8.连接字符（ stop words (and, or, but, of, the, a, etc.)）不是必须的

#9: Remove/control for unwieldy punctuation characters

9.移除/控制难处理（不安全）的标点符号

* Note: Reserved characters only need encoding when not used for their defined, reserved purposes.

#10: Limit redirection hops to two or fewer

10.减少重定向跳转

　　如果客户端请求A，实际重定向B，或者再次重定向C，客户端可以得到C，但是搜索引擎不会记录C页面的排名

#11: Fewer folders is generally better

11.减少子文件

#12: Avoid hashes in URLs that create separate/unique content

12:尽量避免使用URL #创建单独的url /独特的内容

　　#常用于追踪参数 e.g. someone.com/first-page#src=weibo

　　也有例外，见原文链接

#13: Be wary of case sensitivity

13.注意大小写

　　URL是区分大小写的，尽量小写。

#14: Hyphens and underscores are preferred word separators

14.破折号和下划线是首选词分隔符

　　很久以前，搜索引擎只把破折号作为分隔符，现在已攻克，破折号和下划线都是首选分隔符

#15: Keyword stuffing and repetition are pointless and make your site look spammy

重复的关键字并不会提高Page Ranking.
