Testing at StumbleUpon

StumbleUpon is a site where you can download a toolbar for websurfing. With each click, the StumbleUpon toolbar serves you up a webpage based on your interests and the recommendations of other stumblers.

You can rate each page "thumbs up" or "thumbs down" and Stumbleupon learns what you like.

Every sixth webpage is sponsored. That is, an advertiser has paid US$0.05 to Stumbleupon to show that page to you. That's where we come in.

As an advertiser we can see a report of how many people rated our site thumbs up or down. That's a marvellous test since it's a completely impartial rating of our site. Advertisers can target by gender, age, country and subject category.

A few months ago I advertised the old GMtee website to 2,000 people worldwide aged 18-55 and interested in fashion. A 58% majority gave us the thumbs up.

I just repeated the same test for our new website and I am pleased to report that we are now rated thumbs up by an enthusiastic 75%. That's pretty good, I think. Now I'm starting some new experiments with variations on gender and country.

If you are a stumbler and a fan of GMtee, take a moment to give us the thumbs up!
