  Should Fix:
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 7 blocking script resources and 3 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://blockchain.info/Resources/js/jquery.min.js
  • http://blockchain.info/Resources/js/bootstrap.min.js?662df62708e2eab0
  • http://blockchain.info/Resources/js/shared.min.js?662df62708e2eab0
  • http://blockchain.info/Resources/analytics.js
  • http://blockchain.info/Resources/charts/highcharts.js
  • http://blockchain.info/Resources/slick.min.js
  • http://blockchain.info/Resources/js/homepage.min.js?662df62708e2eab0

Optimize CSS Delivery of the following:

  • http://blockchain.info/Resources/overrides.min.css?662df62708e2eab0
  • http://blockchain.info/Resources/css/blockchain.css?662df62708e2eab0
  • http://blockchain.info/Resources/css/blockchain.css?662df62708e2eab0

  Consider Fixing:
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:

  • https://api.blockchain.info/charts/hash-rate?cors=true (60 seconds)
  • https://api.blockchain.info/charts/market-cap?cors=true (60 seconds)
  • https://api.blockchain.info/charts/market-price?timespan=4months&format=json&cors=true&includeLastPoint=true (60 seconds)
  • https://www.google-analytics.com/analytics.js (2 hours)
  • http://blockchain.info/Resources/fonts/icomoon/icomoon.ttf (4 hours)
  • http://blockchain.info/Resources/fonts/montserrat/Montserrat-Medium.ttf (4 hours)
  • http://blockchain.info/Resources/fonts/montserrat/Montserrat-Regular.ttf (4 hours)

  Consider Fixing:
Size content to viewport
The page content is too wide for the viewport, forcing the user to scroll horizontally. Size the page content to the viewport to provide a better user experience.

The page content is 744 CSS pixels wide, but the viewport is only 412 CSS pixels wide. The following elements fall outside the viewport:

  • The element <img src="data:image/gif…AABRxIQAAAOw=="> falls outside the viewport.
Show how to fix
Size tap targets appropriately
Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.

The following tap targets are close to other nearby tap targets and may need additional spacing around them.

  • The tap target <a href="/charts/market-price" class="f-14 em-600 flex-center">Interactive Chart</a> is close to 1 other tap targets.
