URL format6.4
3 URLs are less than ideal
- 3 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.

Analytics8.0
80% of pages use analytics
Google Analytics
- 80.0% of this website is using Google Analytics but 1 pages have no analytics. It is still possible to gather a great deal of information for the other 1 of pages from webserver logs, however complete visitor analysis requires client-side Javascript or an image not found here.
- Consider adding your analytics solution to the pages which aren't currently monitored.
- 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.
Images8.0
100% of images have a clearly defined size
13 images are being resized by the browser
- All images have defined sizes using width and height attributes in the HTML. These attributes are optional, but strongly recommended as they help the browser arrange the page more quickly.
- 13 images are being stretched in the browser.
- The width and height you specify in an image tag should be the same as the source image. If you want to resize an image in the browser, use the CSS width and height properties.

Headings9.0
- 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.
