A sitemap lists URLs that are available for crawling and can include additional information like your site's latest updates, frequency of changes and importance of the URLs. This allows search engines to crawl the site more intelligently.
Robots.txt http://who.int/robots.txt

Great, your website has a robots.txt file.

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 11 blocking script resources and 11 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:

  • http://who.int/sysmedia/media/js/lib/jquery.js
  • http://who.int/sysmedia/media/js/lib/jquery.plugins_r.js
  • http://who.int/sysmedia/media/js/lib/enquire.min.js

  • http://who.int/sysmedia/scripts/shadowbox/en/shadowbox.js

Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.

The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.

  • Only about 57% of the final above-the-fold content could be rendered with the full HTML response snapshot:24.

Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Leverage browser caching for the following cacheable resources:

Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 11 blocking script resources and 11 blocking CSS resources. This causes a delay in rendering your page.

None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.

Remove render-blocking JavaScript:

  • http://who.int/sysmedia/media/js/lib/jquery.js
  • http://who.int/sysmedia/media/js/lib/jquery.plugins_r.js
  • http://who.int/sysmedia/media/js/lib/enquire.min.js
  • http://who.int/sysmedia/media/js/lib/owl.carousel.js

Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.

The entire HTML response was not sufficient to render the above-the-fold content. This usually indicates that additional resources, loaded after HTML parsing, were required to render above-the-fold content. Prioritize visible content that is needed for rendering above-the-fold by including it directly in the HTML response.

  • Only about 65% of the final above-the-fold content could be rendered with the full HTML response snapshot:24.
