The best social media service largely depends on your target audience. If your target audience is age 45 or older, Facebook will be the best platform to market on. If your target audience is 35 and under, Instagram will be a better option for your business. A teenage audience is best targeted on Tiktok. And, a professional audience is best targeted on LinkedIn. Whom you decide to target is usually based on your products or services and overall business goals. Once you know who your target audience is, you will have a better idea of which social media platforms will be best to market on.
