The digital age has revolutionized how homes are sold. The most successful listing agents-those who can sell a home in a predictable time frame for the most money possible-are using new methods that weren't around just six years ago. Despite the current seller's market conditions, many people are leaving money on the table because their listing agents are using outdated methods. Here are some tips for hiring a listing agent who will expose your home to the broadest buyer pool and attract multiple buyers in a bidding war for your property.

1. Do your homework: Read blogs and articles written by real estate experts and get a feel for what it takes to sell a home in the digital age as opposed to the past.

2. Read online real estate agent reviews. Do a Google search for reviews of the real estate agents you're considering for an interview. Look for the agent that has the happiest past customers. If an agent doesn't have a few hundred satisfied customers, why would they be good enough for you?

3. Use an agent who will premarket your home. Premarketing means putting information and images of your home online before it goes on sale. Think of how Apple releases info about its new phones and products long before they go on sale. As a result, there are long lines outside Apple stores on the day those products are released. By premarketing your home, an agent can have buyers lined up the day your home hits the market, with competing bids right out of the gate.

4. Take the time to interview multiple listing agents. Most sellers know so little about the process of selling homes in the digital age that they tend to hire the first agent that they talk to. Select multiple agents to interview based on their customer reviews. If an agent makes a bold claim, don't take it as fact; ask for proof. For instance, the size of an agent's contact list (the people to whom they'll premarket your home) is one factor to consider. Does it list hundreds of people? Thousands? Tens of thousands? Ask to see it, and compare it to those of other agents.

Also, look at their Facebook page. This is a word-of-mouth marketing channel that will ensure a large buyer pool knows about your home before it goes on the market. Count the number of posts on their Facebook page over the past week. If they haven't posted over the last week, reconsider hiring them. Effective agents dominate the real estate conversation on Facebook and social media platforms. The ideal agents will post more than twice daily.

 If you've checked an agent out on Google-proving their past customers were happy, and they've proved they have an extensive buyer database, and use solid premarketing campaigns built around this database and social media-including Facebook, then you've probably found your listing agent.
