Headings4.1

affiliates announcements arctic briefing climate committee director house matters ministerial mission news paper people peter projects schlosser science staff steering white world

  • 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.
  • Many headings (19.0%) 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.
