When used properly, social media can be an effective tool for marketing your real estate business. First of all, make sure you're using a profile different from your personal profile to market your business. State laws may require you to mention or to actually prominently display your broker's name on your Facebook page if you're going to use it for marketing and advertising.
One post a day is a good target to reach for. Occasionally, you want to be able to post a little bit more, sometimes a little bit less. But if you can average about one post a day, that's a pretty good goal. Your social media efforts should be a mix of marketing and information visitors will find useful. While it's important to talk about great listings, new ones that you've just landed, you also need to post things that will make people pay attention when they're not in the place to either buy or sell so that you are kept at the top of their mind for when they actually do want to have a real estate transaction. Consider tips for staging a home and information on trends in your market. If you specialize in a specific type of service, social media is a great place to demonstrate that expertise by covering topics that fall under your specialty.
