In the eye-popping luxury-home market, do more “clicks” online translate into faster sales?

To answer the question, Zillow identified about 4,300 homes in the U.S. valued at or above $3 million that sold in the past 12 months, through the end of March. Zillow then ranked those listings in order of page views in their first 30 days on the site. Turns out, lots of looky-loos make little impact on the speed of the sale.

The 50 luxury listings that got the most traffic in the first month—a median of 4,218 page views—spent 133½ days on Zillow before the sale closed. By comparison, the rest of the $3 million-plus homes sold in that period had a measly median of 552 page views. But these properties sold in a median 129 days—or 4½ days faster than the high-traffic homes.

So even when luxury listings get lots of clicks, “the ratio of signal to noise is much higher,” said Zillow senior economist Skylar Olsen.

The most-viewed luxury home was a 9,500-square-foot modern beach house in Bridgehampton, N.Y., which garnered 11,295 views in its first 30 days and sold for $27.5 million in January. It spent 231 days on Zillow before closing.

The overwhelming majority of top-dollar homes on the list were in California. Ms. Olsen points to two reasons: expensive, competitive housing markets and a large share of mansion-like homes, which Zillow users might be more inclined to browse.

There’s also the celebrity factor. Dana Roberts, an agent with Coldwell Banker in Irvine, Calif., and co-agent Elinor Newman, sold a three-bedroom oceanfront home for $4.85 million in December. Ms. Roberts declined to name the seller, but public records list him as Jonas Hiller, a National Hockey League goaltender currently with the Calgary Flames. Mr. Hiller didn’t respond to requests for comment. The home was listed for sale on Zillow for just 73 days; the city’s luxury home median is 117 days. Ms. Roberts credits the quick sale to their competitive pricing, news stories that identified the owner, and, to an extent, the curiosity factor—some neighbors wanted to see how the house had changed after a recent renovation.
