The potential for online retail growth on desktop and mobile devices
It's interesting to look back at the growth of online sales and think forward to how much further they can grow at the expense of traditional channels. Overall percentage of Ecommerce retail sales are perhaps, surprisingly small at around 7% of sales in the US and 10% in the UK, but with sustained growth. The data for Europe suggests growth rates of 10 to 20%, so for businesses forecasting their future growth rates, the growth target should match or exceed this.
September 2015 update - new UK Ecommerce predictions from Emarketer
These charts from eMarketer give a great visual summary of UK retail Ecommerce sales growth predictions. Although growth rates are declining, they will remain around 10% for next two years with total online retail sales reaching 19.3% by 2019 according to the prediction.
Another chart shows the need to focus on improving mobile ecommerce experiences. The report splits out mobile commerce sales which are already responsible for one third of online Ecommerce sales. The higher growth rates for mobile commerce are striking - currently around 38%.
Remember that, as our compilation of desktop vs smartphone conversion rates shows, conversion rates are significantly lower on smartphones, so the mobile ecommerce experience should also signpost customer journeys that involve purchase via other online and offline channels. Even by 2019 the majority of retail sales will remain offline - the high street won't disappear, just yet fortunately!
