Zillow currently has the broadest reach of any real estate website, but its competitor Trulia is starting to catch up.

Today, the San Francisco-based home search company announced that it saw 54 million unique visitors  to its websites and mobile properties in the month of June, up 55 percent from the same period a year ago. Thats a little less than two million unique visitors shy of the numbers Zillow reported this time last year.

The 55 percent increase includes both Trulia, and its acquisition of Market Leader. As a standalone site, Trulia was up 37 percent year-over-year, compared to a growth rate of 18 percent in June 2013.

Zillow, is well out in front of its rival, and reported that it saw almost 83 million unique users in the past month, up 49 percent from June 2013. But its rate of year-over-year growth is starting to slow, compared to where it was last year. Since October, Zillows monthly uniques have seen year-over-year growth of less than 60 percent.

Of course, part of that just has to do with how large Zillows footprint has become. On average, Zillow has added five million more unique users a month in 2014 than it did in 2013, but the companys user base has grown so large that its percentage growth has tapered off.

But Trulia has been working on aggressively raising awareness of its products with a massive advertising spend over the past several months, and it seems to be paying off. The company reported that it saw an average of 45 million unique monthly visitors in the first quarter of this year, and reported that it received 51 million unique visitors last month.

With its acquisition of Market Leader, Trulia has been able to boost its traffic through the addition of a new set of online properties that face a different set of customers. Zillow doesnt have a set of products that are similar to Market Leader, which provides a variety of tools for real estate agents. Trulia acquired the Bellevue-based company for $355 million last year.

Trulia is breaking traffic records with this new surge in users, and looks like its on pace to pick up more users over peak home buying season this year. Its entirely possible the company could surge in growth to catch up with Zillow, or at least further close the wide gap that exists between the two companies.
