Headings2.4

worldwide

  • 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 optimisation.
    • Define meaningful headings for all webpages. This is likely to help this website's search engine placement and assist visitors in navigating content.
  • Many headings (11.0%) 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.
  • 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 format5.2

  • 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.
  • 1 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.
