5. Findings - By Audit Criteria

HTTPS

https-audit-results

Retail, Government and Non-Profit sites lead the way in adoption of HTTPS, followed by the General Services category, which includes a lot of ISP and telecoms providers. Finally, whilst the Banking & Financial Services category performed comparatively poorly here it must be said that almost all the high street banks in the data-set were using HTTPS throughout. Of the sites that are not, notable exceptions include Bank of England* and RBS.

 

*Between the time of the audit and final review of this data, the Bank of England has implemented a 301 redirection from HTTP to HTTPS

 

Provides Content Sized for Mobile Viewport

content-sized-mobile-screen-results

The News & Media category often leads in terms of feature adoption in this study; and again scores highly in terms of content sizing. Interestingly the Academic and Travel & Leisure categories are joint second at 94% optimised for mobile.

Over 16% of the retail category sites failed to provide content optimised for mobile users – a tangible percentage given the commercial nature of these sites.

 

Speed – Interactive in Less than 10 Seconds

interactive-less-10-seconds-results

Over 16% of the retail category sites failed to provide content optimised for mobile users – a high percentage given the commercial nature of these sites.

In addition the highly commercial Travel & Leisure and Retail channels performed poorly here, meaning potential loss of commercial opportunity.

 

Service Worker & Add to Home Screen

As Progressive Web App features are fairly new, we were not expecting to find adoption in this first year of the study, therefore it was interesting to see a handful of sites start to adopt these features. We have grouped these two criteria together as there is not much to remark in comparing by category. Please note: as the results are so small in each criterion we have presented the data in numbers as opposed to percentages.
