URL format6.0
3 URLs are less than ideal
- 3 URLs are 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.

Headings7.0
- All pages were found to use defined headings. This is excellent as it allows visitors and search engines to summarise the content of webpages quickly. Correctly defined headings aid accessibility and are particularly important for search engine optimisation.
- Some pages did not define headings correctly. The H1 tag should be used for the most top-level heading, with H2 being used for sub-headings and H3 for further sub-headings and so-on. Not conforming to this convention may confuse visitors.
- Ensure that headings are defined in a semantically correct way, i.e. always start with a H1 tag. This is used to summarise the page content. Further tags (H2, H3, H4 etc) are meant to summarise and partition sections within the content.

Server behaviour9.8
404 page
Compression
- 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.
- 2 of the pages of this website follow the best practice of using a permanent (HTTP 301) redirect between URLs with/without trailing slashes. These pages are ideal.
- Adding or removing a trailing slash to 2 of the URLs of this site returns an error page (404). This is OK as no content is being duplicated, but visitors might try browsing to the pages of this website with or without a trailing slash. Ideally, the alternate URL should redirect to the correct page.
- Add a 301 redirect from the other version to the canonical URL.
Unhandled alternate URLs
- Add a 301 redirect from the other version to the canonical URL.
- This test is not applicable as this website appears to be on a subdomain.
Mobile10.0
