NEW YORK -- After a tough day at work as a publicist in Minneapolis, Becca Bijoch would often indulge in a little retail therapy. She usually headed out to the stores as she did not care much for online shopping.
That changed last year when the 26-year-old joined Pinterest, a photo-sharing website that allows users to "pin" images to online bulletin boards based on their interests and to follow others. Bijoch says she has found all sorts of things that she bought after seeing them on Pinterest, from great kitchen tools on CrateandBarrel.com to clothes at Asos.com.
"I'm probably spending more now. I'm on the couch at night, after having two glasses of wine," Bijoch says, but she has no regrets. "I tell everyone that Pinterest has changed my life."
Pinterest, which was the fastest standalone website to hit 10 million unique visitors a month, now has 25 million members, of whom many - like Bijoch - are young, female, well-educated and have disposable income.
Retailers are hankering after these users, but it is sometimes difficult to nab them because Pinterest is an ad-free website and "pins" flourish virally. While many retailers have learned how to interact with consumers on Facebook and Twitter, they are still struggling to figure out Pinterest and the ways to make money out of reaching shoppers through it.
"It's a huge window-shopping platform," says Kyla Brennan, chief executive of HelloInsights, a Santa Monica, California company that provides analyses of Pinterest use. "It helps people find what they really like. Does it encourage people to be a little impulsive? Of course."
E-commerce experts say Pinterest generates more dollars per users than some other social media sites, even though Facebook, the world's largest social network with more than a billion users, is a leading driver of shopping by volume.
Pinterest shoppers, on average, spend nearly $170 per session, according to a study by RichRelevance, an e-commerce consultant, which tracked 700 million shopping sessions. In comparison, Facebook shoppers spend $95 per session, while Twitter shoppers spend $70.
Major retail brands with a presence on Pinterest include L.L. Bean, with more than 5 million followers; Nordstrom Inc, with more than 4 million followers; and Lululemon Athletica Inc with close to 2 million. Other major players like Gap Inc and Urban Outfitters Inc have fewer followers on the site, but are growing.
The three-year-old Pinterest recently closed a $200 million round of financing, which raises its value to $2.5 billion.
Most companies' Pinterest activity is handled by their social media teams, but the efforts differ from promotions on Facebook and Twitter because Pinterest boards are interest-based and not timeline-based. Nordstrom's Facebook page, for example, features a couple of products daily that are on sale or seasonally interesting, but its Pinterest page is an evergreen collage of fashion lifestyle images.
As there is no direct advertising and Pinterest is still growing, the marketing cost to businesses of acquiring new users is lower than other sites, says Daniel Maloney, CEO of PinLeague, a consultancy that tracks social media usage.
"The current cost of acquiring a Pinterest follower is a penny to 50 cents, depending on type of business. That compares to 50 cents to $2.50 on Facebook," he said.
One of the top ways to reach followers seems to be to do anything but try to sell products. L.L. Bean's most popular board, for instance, is devoted to pictures of woodland creatures - its most popular pin is a picture of a cat dressed up to look like a bat.
"While we do measure traffic coming to llbean.com and llbeansignature.com from Pinterest, we are not currently promoting the platform as a selling channel," says Laurie Brooks, senior public relations representative for the company based in Freeport, Maine. Internal metrics show Pinterest users spend more than others, and that traffic is on the increase even if, overall, it is less than what comes from Facebook, she adds.
L.L. Bean, like many other retailers, has not offered discounts through Pinterest, but it has sponsored contests. So has Nordstrom, which did a bridal-focused sweepstakes in January.
"Our followers share and save compelling imagery and merchandise - period. Our boards aren't focused on bargains or coupons," says Bryan Galipeau, who is group manager of social media at Nordstrom's Seattle headquarters. "We think it's important to take a broader view of Pinterest because that's also how our customers see it."
Fashion retailer Gilt.com's "Pin to Win" contest offered a $2,500 shopping spree to women who shared certain images from their wedding dress collection. Gilt also rewarded those who received 50 re-pins of a children's dress the chance to buy the item for 77 percent off.
Similarly, fashion-seller Karmaloop.com offered a trip to Paris for the best outfit pinned to one of its boards.
Other goodies from retailers include AMC Theatres' giveaway pinboard where users can win movies posters and other memorabilia. Wal-Mart Stores Inc ran a contest about inspiring people to be environmentally conscious.
Even if you could win something by shopping through Pinterest, consumers need to exert some impulse control.
Since most of what is "pinned" on the site is aspirational, people can end up spending way more than when they click through from other social media sites.
