  • To appear higher in search engine results, consider link building activity as a way to build your search ranking. Be careful though, because incoming links which are obviously artificial are likely to be detected by search engines and could have an adverse effect. (read more)
  • 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. (read more)

  • A significant amount (20.0%) of pages do not use defined headings. This means that users and search engines may find it harder to determine the content of this website's pages. Correctly defined headings aid accessibility and are particularly important for search engine optimization.
    • Define meaningful headings for all webpages. This is likely to help this website's search engine placement and assist visitors in navigating content.
  • 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.

URL format8.4

  • One URL is 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.
  • 1 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.
