Experian Hitwise put out a report today looking at how popular online pinboard site Pinterest is getting.

While this is only showing U.S. data, this graph pretty much says it all:

Ok, maybe it doesn’t say it all. Here are some highlights Experian Hitwise shared with us in an email:

• Pinterest recently emerged as one of the top 10 websites within the Hitwise Social Networking & Forums category.
• The invitation only site received nearly 11 million total visits during the week ending December 17, 2011, almost 40 times the number of total visits versus just six months ago (week ending June 18, 2011).
• Pinterest content has something for everyone, but the site is dominated by images featuring home décor, crafts, fashion, and food. Not surprisingly, visitors to the site in the 12 rolling weeks ending December 17th skewed female (58%) and between the ages of 25 and 44 (59%).
• Pinterest and the Social Networking & Forums category both receive their highest share of visits from California and Texas. However, the Social Networking category as a whole over-indexes on share of visits from Northeastern states while Pinterest over-indexes on visits from the states in the Northwest and Southeast. This data indicates that Pinterest visitors have a different profile versus their counterparts visiting other social networking sites such as Facebook and YouTube.
• In fact, nine of the top ten over-indexed states for Pinterest visitors also over-index for the Hobbies and Crafts category (versus the online population) which is expected given the abundance of crafts content on the website.
• When comparing the Mosaic USA 2011 types that visit both Pinterest.com and Hobbies and Crafts websites during the 12 weeks ending December 17, 2011, the data shows that Boomers and Boomerangs are the group most likely to visit, particularly the Pinterest website (comprising over 10% of visits). This group of consumers is characterized as baby boomers and young adults who are heavy web users who spend time on house and garden, sports and fitness, and family-oriented websites. This information is useful to companies who wish to target their content to be “pinned” by Pinterest users.

Clearly Pinterest is going to be one of those sites to watch heading into the New Year.
