Facebook marketing is the practice of using a business Page, posts, Groups, and optional ads to reach customers, build trust, and drive enquiries. Despite newer platforms, Facebook remains valuable for small businesses because its audience is broad, local discovery is strong, and tools like reviews, events, and messaging are built in. A practical approach has three parts: a complete business Page that clearly states what you offer, where, and how to contact you; regular posts that share useful information and show your work; and quick, friendly replies through Messenger. You do not need a large budget to begin, since organic posts and community engagement can carry you a long way. The most common mistake is creating a Page and then leaving it idle. Instead, post consistently, respond to reviews and messages promptly, and use events or Groups where they fit your business. Decide on a sustainable rhythm, such as a few posts a week, and review which updates earn comments, shares, and enquiries so you can do more of what works.
