The 2011 NAR Member Guide reports that nearly two thirds of all Realtors have had a website for at least five years. Of that number, half use social media and only 10 percent blog on a daily basis.

According to AgentGenius, NAR reports that the most common information on Realtor websites is nothing blog- or social media-related, but their listings. Realtors reportedly spend a median of $250 to maintain a website per year, which is fairly low given that a quality IDX alone is more than $250 per year.

In addition, NAR members average three inquiries — or 3 percent of their business — from their websites. However, NAR also found 75 percent of its members use smartphones, an increase of 34 percent since 2009, and a positive step for an industry, whose average age is 56.
