The onset of the Christmas shopping season brought increased traffic to online retail sites, with the jewelry/luxury goods/accessories category experiencing the strongest growth, followed by the mall, music, and flowers/gifts/greetings categories. High-street retailers were particularly influenced by the seasonal uptick, with retailers such as HMV, the John Lewis Partnership and the Dixons Stores Group all enjoying strong visitor growth. The e-Cards and Shipping categories also achieved gains, while the Royal Mail Group property grew 31 percent to more than 4 million visitors.

Interestingly, visitation to online dating sites also grew significantly in December, as lonely hearts reached out to one another during the Christmas season. Meanwhile, Facebook.com continued its ascension towards the top of the online rankings -- having captured the fifth spot in the ranking in September, the social networking property moved up yet again in December to rank as the fourth most popular property.
