XML Sitemap Missing

Your website does not have an XML sitemap - this can be problematic.

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://blockchain.info/robots.txt

Great, your website has a robots.txt file.
Analytics Missing

We didn't detect an analytics tool installed on this website.

Web analytics let you measure visitor activity on your website. You should have at least one analytics tool installed, but It can also be good to install a second in order to cross-check the data.

  Should Fix:
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 8 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?8766bdde0e502bb5
  • http://blockchain.info/Resources/js/shared.min.js?8766bdde0e502bb5
  • http://blockchain.info/Resources/analytics.js
  • http://blockchain.info/Resources/js/navbar-analytics.js
  • http://blockchain.info/Resources/charts/highcharts.js
  • http://blockchain.info/Resources/slick.min.js
  • http://blockchain.info/Resources/js/homepage.min.js?8766bdde0e502bb5

Optimize CSS Delivery of the following:

  • http://blockchain.info/Resources/overrides.min.css?8766bdde0e502bb5
  • http://blockchain.info/Resources/css/blockchain.css?8766bdde0e502bb5

  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)

Size content to viewport

  • The element <img src="data:image/jpg…cWKFb7X0ZWVf/Z"> 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.
