An excellent, and free, way to keep up with the news is with RSS news feeds or alerts in your email or a news reader. Click here for instructions. Use keywords like "real estate marketing" to get alerted to the latest trends, products and services.
Don't jump on every bandwagon offered. There's a lot more ineffective marketing out there than the good type. Read daily though, study the promises and services, and then act on them if they look promising. Again, track results and don't get locked into any long-term obligations.
