  • 3 pages of this website were found to be using the tag <b>. It is widely regarded that use of presentational elements like <b> should be avoided.
    • Replace all the instances of presentational tags with a semantic alternative. This means where possible, use semantically correct HTML and then style it with CSS.

  • 2 of the 5 tested pages of this site appear to use tables to lay out content. This is very bad, as using tables for layout is not necessary and they should only contain tabular data.
    • Change this website to make use of DIV elements and CSS to create the desired layout. Only use tables for tabular data (e.g. a pricing table).

URL format5.6

  • 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.
  • 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.

      Page extensions

  • 60.0% 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.

  • This website delivers a mobile optimized version of the HTML when accessed on a phone. This is good because visitors on a mobile device will be able to access this website easily.
    • Having mobile optimised HTML is good, but the best way of adapting a website for different screen sizes is to use CSS media queries.

Server behavior8.8

Yes404 page

YesCompression

  • 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.
  • 3 of the pages of this website return page content with or without a trailing slash on their URLs. Search engines might see these as separate pages with duplicate content which they could penalize for.
  • This test is not applicable as this website appears to be on a subdomain.

  • 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 headings (3.0%) 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.
