Now a recent study suggests it prompts consumers to make purchases. Some 21% of respondents to a recent survey with a Pinterest account have purchased a product after seeing a picture on the site.

The PriceGrabber survey of 4,851 U.S. online consumers conducted between March 13 and 26 reveals that respondents who purchased a product based on seeing it strictly on Pinterest were asked to select all items purchased: 33% said food and cooking; 32%, fashion and clothing; 30%, home decorating; and 26%, crafts.

Some 37% of Pinterest account holders log in a few times weekly and most have created between two and five Pinboards; 28% said they log in a few times a month; 15%, once daily; 10%, a few times a year; and another 10%, numerous times a day.

When Pinterest account holders were asked how many Pinboards they have created, 29% said between two and five; 26%, between six and 10; 19%, none; 16%, one; and 10%, more than 10.

Searching for recipes remains the favorite interest. Some 70% of Pinterest account holders cite cooking and recipes as the top item pinned. When respondents with a Pinterest account were asked to select all of the types of items they pin, 70% cited cooking inspiration and recipes; 65%, home decorating; 53%, craft ideas; 41%, fashion and shopping ideas; 34%, entertaining ideas; and 33%, gardening.
