cxpartners and Google – building a picture of the mobile web

Earlier this year, Google and cxpartners set out to research just how fast and usable the mobile web is. The aim was simple – show best-in-class examples of the largest brands in Europe to help businesses benchmark their own usability and speed performance.

To do this, Google used SimilarWeb’s data to identify the top-20 transactional sites in each country (UK, Germany, France, Netherlands, Spain, Italy and Sweden) and in each chosen vertical (retail, travel and finance).

The result was that we reviewed 316 sites, collating the findings into three executive summaries: for retail, travel and finance.

MEET THE MOBILE MASTERS: People increasingly expect mobile sites to be fast and easy to use. To help brands understand the best examples of mobile site usability and speed, Google has reviewed 316 Travel, Retail, and Finance sites across seven European countries to determine who has mastered mobile and who still needs to pick up speed.
Individual executive summary reports highlight key findings within the retail, travel and finance verticals.

So what did we find out?

The average speed rating across all verticals and all countries is either ‘poor’ or ‘critical’ according to Google’s speed benchmark.

Why is site speed worth paying attention to? Well, research has shown that 48% of consumers expect page loads in under a second so the risk of consumers going to a competitor's site due to slow speeds is too high to ignore.


Site speed was the slowest on average in the travel sector, the UK average site speed was 5.7 seconds. That’s a full 1.7 seconds slower than Google’s critical rating of >4secs.

All country averages fail our speed benchmark. In fact, we describe a speed of greater than 4 seconds as critical - requiring immediate attention.
Site speed averages were deemed critical in every country, suggesting messages about the value of improving site speed haven't yet landed.

In usability, UK travel sites came second to the Netherlands with an overall average of 78% with several sites, such as British Airways, scoring 100% in certain categories.


Across in the world of retail, we found that online fashion retailer ASOS was the most usable in four out of seven countries and that in retail, average site speed was higher than in travel or finance at 3.8 seconds (although still considered ‘poor’). Some sites managed 100% ratings for some aspects of their mobile sites, such as Heine, in Germany:

Heine's mobile website achieved a 100% score for some categories
Some sites passed all of the usability principles in specific categories. In this case, Heine excelled at multi-device and multi-channel use.


Whilst there were some high individual scores in usability in the finance sector, the overall picture is less convincing. The average usability rating for most countries hovers around 50%, with the UK sitting just above this at 52%.

On average, finance sites in Netherlands performed best against the usability principles, followed by Italy, Germany, UK, Sweden, Spain and France
Average % of usability principles passed by finance sites within each country.

Despite this, price comparison site achieved 100% in three out of four stages in the customer journey and AA Insurance posted an impressive 86% overall usability score.

The opportunity

This review is a perfect point for businesses to recognise the importance and the impact usability and site speed have on the customer experience. The results show that there is still plenty of room for brands to improve their mobile site experience and increase conversions.

With a predicted six billion people having internet access by 2021 and most of those accessing it through a smartphone, the case for having a leading mobile website has never been stronger
