Top priorities for website improvement

  • Consider a leading website analytics solution, such as WebTrends or Google Analytics. (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)
  • Choose one domain that you would like to use and then set a permanent (HTTP 301) redirect to forward users who visit the other. (read more)

Analytics0.0

Help

0% of pages use analytics

No Analytics SolutionNo

  • None of this website is using any recognised analytics software. It is still possible to gather a great deal of information from webserver logs, however complete visitor analysis requires client-side Javascript or an image not found here.
    • Consider a leading website analytics solution, such as WebTrends or Google Analytics.
  • Note that this test can only detect recognised analytics solutions. If an analytics solution is new, obscure or used in a non-standard way (e.g. it has been customised) it may not be detected.

Meta tags2.0

Help

  • All pages include at least some metadata, but no pages have a description meta tag. The description meta data is important as it appears on Google's search result pages.

Server behavior8.2

Help

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.
  • This website follows the best practice of using a permanent (HTTP 301) redirect between URLs with/without trailing slashes. This is ideal.
  • There is duplicate content on http://iucr.org and http://www.iucr.org. This is bad, as technically they are classed as two different websites. Search engines may lower a website's rank if they find the same content on two different URLs.
    • Choose one domain that you would like to use and then set a permanent (HTTP 301) redirect to forward users who visit the other.

Amount of content8.6

Help

Rendering Chart...

  • This website has an average of 3,771 words per page. The amount of content on a website has been shown to correlate with its search engine ranking.

URL format8.8

Help

  • 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.

  • 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 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.
