- Make sure your users can verify their website in website management suites such as Google’s Webmaster Tools.
- Choose a unique directory or hostname for each user.
- Set useful and descriptive page titles.
- Allow the addition of tags to a page.
- Allow your users to use third-party analytics packages such as Google Analytics.
- Help your users move around.
- Help search engines find the good content from your users.
