Top priorities for website improvement

  • Check how the website looks using a mobile and a tablet. Consider adding mobile-only styling using media queries. Some websites employ other techniques for mobile visitors which we cannot currently detect. (read more)
  • Consider a leading website analytics solution, such as WebTrends or Google Analytics. (read more)
  • Enable GZIP compression on your web server or in your application. (read more)


0% of pages use analytics

No Analytics SolutionNo

  • None of this website is using any recognised analytics software. It is still possible to gather a great deal of information from webserver logs, however complete visitor analysis requires client-side Javascript or an image not found here.
    • Consider a leading website analytics solution, such as WebTrends or Google Analytics.
  • Note that this test can only detect recognised analytics solutions. If an analytics solution is new, obscure or used in a non-standard way (e.g. it has been customised) it may not be detected.

  • None of this website appears to be fully optimised for viewing on a mobile or tablet (using CSS media queries). It is important to make sure your content can be viewed easily across a wide range of devices as a growing percentage of web browsing is now done on phones and tablets.

URL format5.2

  • 4 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.
