  • Add meaningful anchor text that describes the link's destination. If the link contains an image, ensure you have provided alt text. (read more)
  • Consider the amount of text on this website and increase it if appropriate. (read more)
  • Enable GZIP compression on your web server or in your application. (read more)

Amount of content3.5

Rendering Chart...

  • This website has an average of 75 words per page. The amount of content on a website has been shown to correlate with its search engine ranking.
    • Consider the amount of text on this website and increase it if appropriate.
  • 2 pages of this website have very little content (20 words or less).
    • Ensure all pages have a sufficient amount of content.

Server behavior4.0

Yes404 page


  • This website handles missing pages correctly by sending a 404 HTTP status code.
  • This website was not served using GZIP encoding. GZIP compression is widely supported and reduces the load time of a web page.
  • 2 of the pages of this website return page content with or without a trailing slash on their URLs, but they use a canonical tag to denote the correct version. This is usually ideal, as search engines will know which version to index, but there are links on this website which point to the non canonical version.
  • There was no website found on This is bad, as visitors might presume they can visit this website by visiting that address.
    • Put a permanent (HTTP 301) redirect to on

URL format6.8

  • 2 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.
  • 2 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.

  • All pages were found to use defined headings. This is excellent as it allows visitors and search engines to summarize the content of webpages quickly. Correctly defined headings aid accessibility and are particularly important for search engine optimization.
  • 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.
