  • Add width and height attributes to all image tags. The width and height you specify should be the same as the source image. If you want to resize an image in the browser, use CSS. (read more)
  • 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)

Server behavior4.4

No404 page


  • This website does not return a 404 error HTTP status code for missing pages. This is bad because search engines like Google might mistake this for a real page of content.
  • This website was not served using GZIP encoding. GZIP compression is widely supported and reduces the load time of a web page.
  • This website uses a temporary (HTTP 302) redirect from to This is OK, but a permanent (HTTP 301) redirect is considered best practice.
    • If possible, change the temporary redirect to a permanent (HTTP 301) redirect.

URL format4.8

  • 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.
  • 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.
