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)
  • 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. (read more)
  • Add meaningful anchor text that describes the link's destination. If the link contains an image, ensure you have provided alt text. (read more)
