Internal links3.7
- 39 links have no text describing their destination. Links on a page should describe their destination for the benefit of both screen readers and search engine spiders.
- Add meaningful anchor text that describes the link's destination. If the link contains an image, ensure you have provided alt text.
Empty link text
- Add meaningful anchor text that describes the link's destination. If the link contains an image, ensure you have provided alt text.
URL format5.2
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.
- 3 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.
- 40.0% of URLs include an ID query parameter (e.g. www.example.com?sessionid=1234).
- Avoid use of any query parameter ending in id, e.g. 'sessionid;' Google explicitly states that it will not include pages with this format in their index. Consider URL rewriting as an effective and transparent means of creating appropriate URLs.

Headings9.6
- 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.
- Many headings (8.0%) were found to be empty, or incorrectly defined. Empty or invalid headings are of no value to search engines and make a website less accessible.
- Make sure all headings have content which is relevant to the page of content.
