Server behaviour7.5

Yes404 page


  • 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, but they use a canonical tag to denote the correct version. This is ideal, as search engines will know which version to index.
  • Adding or removing a trailing slash to one of the URLs of this site returns an error page (404). This is OK as no content is being duplicated, but visitors might try browsing to the pages of this website with or without a trailing slash. Ideally, the alternate URL should redirect to the correct page.
  • 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

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