URL format7.6

  • One URL is particularly hard to type or remember.
    • Consider URL rewriting as an effective and transparent means of creating appropriate URLs. URLs using unusual characters (such as semi-colons or underscores), long numerals or complex phrasing are very difficult for real people to use or exchange. They also tend to be less favoured by search engines. Wherever possible ensure web addresses are 'human readable' - i.e. they should be easy to read, remember and type. In particular, avoid the use of obscure characters (including the underscore, which is not widely understood by non-technical users, or particularly memorable) and long numerals, e.g. example.com/23857984325.
  • 1 URLs are 'dirty'. 'Dirty' URLs include one or more parameters after a question mark (e.g. www.example.com/?pagename=news), instead of a clean URL (e.g. www.example.com/news). Dirty URLs should generally be avoided wherever possible - they are almost impossible for human beings to remember, may expose the technology of the website to hackers and can confuse search engines among other problems. Their use is sometimes necessary for specific applications, and acceptable in small amounts.
    • Remove or reduce the number of query parameters in URLs. Consider URL rewriting as an effective and transparent means of creating appropriate URLs.
