Simply put, the faster your site, the more you increase your bottomline. We explore how site speed affects conversions in this post.
As our lives become increasingly busy it is important for companies to react to customer expectation and reliance upon quick and efficient access to data, products and services. In fact Kissmetrics produced an interesting infographic on ‘How loading time affects your bottom line’, which has statistics upon typical user expectations and behaviour.
The graph below shows the audience segmentation per device type of an example client who receive in excess of half a million visitors a month. Over the last year mobile traffic has almost doubled with traffic from tablet devices now at nearly 15% from 10% this time last year:
The continual creation and improvement to mobile devices means more and more internet users are accessing the internet whilst on the move. We are increasingly seeing cases whereby sites receive a higher level of mobile and tablet traffic than they do desktop, with site speed becoming a more important factor in how the site performs and converts.
Above is the exit and bounce rate against page load times for the mobile traffic to an e-commerce site.
Data taken from Google Analytics (July 2013 – June 2014).
Above is the exit and bounce rate against page load times for the traffic to a lead generation site.
Data from Google Analytics during (July 2013 – June 2014).
Both charts display that the exit metrics are generally larger for pages that take longer to load. Essentially we are seeing that for pages with longer page load times, a larger proportion of users are leaving the site. Based upon the user perceptions and expectations discovered earlier we believe users are becoming frustrated at the underperformance and leaving the site. Additionally, and particularly across mobile devices, users are more likely to be distracted whilst waiting for pages to load.
Site speed is not simply a usability issue, it is an issue that affects SEO, PPC other acquisition channels.
As well as upon mobile devices site speed is important for desktop sites and even a sites ranking position within Google. This has been under much debate with little clear correlation between site speed and ranking but simply put if Google is unable to crawl the site quick enough then it to will be unable to provide the service its users require.
This is why it is important that we are joined up with the other acquisition channels and that we look at Site Speed during Conversion Optimisation campaigns.
