TOP SITES FOR UNDER 12s

ClubPenguin.com

Unique audience under 12: 196,000

A virtual world in which kids adopt a penguin and steer it around an arctic-themed environment where they meet other penguins and perform tasks such as recovering treasure from a shipwreck. A subscription service - for £3.95 a month - entitles the owner to greater perks such as penguin outfits and igloo furniture, but paying customers still have to carry out tasks to earn rewards.

Stardoll.com

Audience: 108,000

Users customise a virtual doll - which looks like a celebrity or themselves - and which can then meet other dolls and visit environments such as shopping malls and the beach. (Alicia Keys, Anastacia and Brad Pitt are among the dolls that users can pick.) Dolls then buy ‘Stardollars’, which can then be spent on clothing and other virtual goods. Tops cost about 18c (10p) and dresses 24c. Several real life fashion brands, such as Sephora and DKNY, have created ‘virtual collections’ on the site.
