November 2010 saw a significant rise in retail and coupon sites in the US, according to digital analytics provider comScore Media Metrix. Among the top-gaining retail subcategories for the month were Jewelry/Luxury Goods/Accessories, Toys and Consumer Electronics, each growing at least 25% versus October.

The rise in web activity within these categories points to consumers increasingly wanting to take advantage of retailers’ pre-holiday promotions. For one, the Monday after Thanksgiving, known as Cyber Monday, came in as the heaviest online spending day on record in the US.

As a whole, toy sites witnessed a large growth during the month, increasing 35% to 27 million visitors. Toys ‘R’ Us websites earned the top spot, followed by The LEGO Group and Disney Shopping. AmericanGirl.com came in fourth followed closely by Fisher Price.

Americans are also increasingly scouring coupon-based sites. A reported 44 million Americans visited a coupon site during November, up 40% since October. Groupon ranked as the number-one coupon site with 10.0 million unique visitors (up 54%).
