If you've attended any kind of presentation about marketing your business, you've probably been told that you need a Facebook page ASAP. While it's a good idea to have a Facebook page for your home inspection business - it's free, why not? - it doesn't need to be at the top of your priorities if you're just starting out. It should be part of your overall online marketing strategy.
Before jumping into setting up a Facebook page, make sure you have a solid foundation for your online presence foundation. This includes having a website, a Google my Business page, a Yelp page, and listings on local and national business directories.
You don't need to set up a Facebook business page unless you plan on keeping up with it. Just setting one up and then never posting anything is worse than not having one at all, because if people search for you and find an outdated page they might think you went out of business. If they don't find one at all they might think you're just not on Facebook.
Social media marketing is not something you should look at as a way to directly generate business, it's more of a way to communicate with your target audience. This may include past clients, potential customers, and real estate agents. However, instead of just blindly promoting your services, a much more effective strategy to increase your follower base is to provide valuable and interesting content.
