Analytics2.0
20% of pages use analytics
Google Analytics
- 20.0% of this website is using Google Analytics but 4 pages have no analytics. It is still possible to gather a great deal of information for the other 4 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.
Meta tags2.0
- All pages include at least some metadata, but no pages have a description meta tag. The description meta data is important as it appears on Google's search result pages.
- Make sure that all the pages of this website include a meta description. If you don't include one, Google will choose a sample of text from the page to appear in the search engine result. By including a meta description, you can control how your search engine result will appear.

URL format5.2
4 URLs are less than ideal
- 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.
