URL format4.8

  • 4 URLs are 'dirty'. 'Dirty' URLs include one or more parameters after a question mark (e.g., instead of a clean URL (e.g. 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.
  • 1 URLs include a file extension.
    • Avoid use of file extensions wherever possible. File extensions appear at the end of web addresses, and have several negative effects. They make the address harder to remember or type (particularly for non-technical users), and can reveal the underlying technology of the website making it very slightly more vulnerable to hackers. They also tie the implementation of the website to a specific technology, which can make subsequent migration of URLs difficult. Consider URL rewriting as an effective and transparent means of creating appropriate URLs.
  • 100.0% of URLs include an ID query parameter (e.g.
    • Avoid use of any query parameter ending in id, e.g. 'sessionid;' Google explicitly states that it will not include pages with this format in their index. Consider URL rewriting as an effective and transparent means of creating appropriate URLs.

Server behaviour8.5

Yes404 page


  • This website handles missing pages correctly by sending a 404 HTTP status code.
  • This website was served with GZIP encoding. This is very good because it reduces the loading time of a web page.
  • 3 of the pages of this website return page content with or without a trailing slash on their URLs. Search engines might see these as separate pages with duplicate content which they could penalise for.
  • One page of this website returns page content with or without a trailing slash on its URL, but it uses a canonical tag to denote the correct versions. This is usually ideal, as search engines will know which version to index, but there are links on this website which point to the non canonical version.
  • This test is not applicable as this website appears to be on a subdomain.
