Brafton has reported that ecommerce will approach $200 billion this year, which should inspire internet marketers to invigorate their online campaigns. A report from eMarketer offers a breakdown of quarterly ecommerce growth, and brands should be prepared for Q2 if they want to catch their share of online cash.

According to the report, online sales will reach $42.5 billion this quarter. This represents a 13.7 percent increase over Q2 2010, and it continues an upward trend that started last quarter. In Q1 2011, ecommerce hit $41.5 billion – a 13 percent increase over the same period in 2010.

Marketers trying to decide where to invest their online marketing dollars should consider that eMarketer believes “three major developments will spur this growth: mobile commerce, social commerce and daily deal sites.”

This theory is consistent with Brafton's earlier reports. We've covered news indicating that mobile internet usage is on the rise, social media marketing enhances CTRs and daily deal sites drive revenue gains for brands.

We've also reported that a GroupM survey shows search engines are the leading path to conversion, so marketers may want to prepare SEO campaigns for mobile, social and local audiences to maximize their chances of bringing in ecommerce this quarter (and this year).
