Custora, a provider of e-commerce marketing analytics software, has released its Custora E-Commerce Pulse, a real-time dashboard providing U.S. e-commerce key statistics and benchmarking data.

According to the Pulse, for the holiday period starting Nov. 1, U.S. holiday e-commerce revenue grew by 18 percent compared to the equivalent period in 2012. Visits to e-commerce sites increased by 23 percent vs. 2012.

The Pulse is based on Custora’s analysis of over 70 million online shoppers and over $10 billion in e-commerce revenue across more than 100 U.S.-based online retailers.

Other notable e-commerce holiday trends: 

• Mobile is growing fast, with almost a third of all online purchases now made on phones or tablets: Share of e-commerce purchases made on mobile devices (phone and tablet) jumped from 19 percent in 2012 to 28 percent in holiday 2013.

• Apple continues to dominate e-commerce, but Android is gaining share: iOS devices (iPhone and iPads) account for 82 percent of e-commerce mobile purchases, while Android devices (phones and tablets) account for only 17 percent, up from 15 percent in 2012.

• Social commerce isn't happening (yet): Facebook and Twitter have not generated a significant volume of e-commerce purchases this holiday season.

The Custora Pulse is updated daily throughout the holiday season; visitors can sign-up to receive email updates on key dates including Black Friday and Cyber Monday. The Pulse also enables online retailers to easily benchmark themselves against U.S. e-commerce industry performance along key performance metrics.
