ChannelAdvisor, an ecommerce solutions vendor, reported on Tuesday that Green Monday sales increased 19 percent over the same day in 2010. Green Monday was officially dubbed as such by eBay in 2007; it marks the final day of ecommerce shopping where regular shipping schedules will guarantee arrival before the Christmas holiday.

The company analyzed data from major web retailers and found that some experienced as much as 45 percent Green Monday sales growth over last year. While the average revenue gain was 19 percent, overall holiday shopping sales have increased 22 percent based on ChannelAdvisor’s figures. (The company measures the holiday shopping season as Thanksgiving through Christmas Eve.)

Businesses using paid search campaigns saw their sales increase 23 percent over a year ago.

The company expects holiday shopping sales in-store and online to continue their growth in the final days of the season. Moreover, Free Shipping Day, this Friday, will likely generate more sales for businesses trying to appeal to last-minute shoppers.

While ChannelAdvisor noted the effectiveness of PPC campaigns, it’s likely that SEO campaigns can be equally beneficial for B2C companies looking to improve sales during the holiday. Brafton reported recently that consumers check an average of 10.4 sources online before finalizing any purchase decisions. Content marketing campaigns can help businesses appeal to shoppers with informative, keyword-rich content.
