SMM refers to both organic and paid digital marketing efforts on social media networks like Facebook, Twitter, and LinkedIn. Social media marketing encompasses many different activities and many consider this to be the future of digital marketing. While social media channels become the hub of activity online in the modern age, this is where consumers engage each other in conversation. Furthermore, it’s also the nerve center of business and brand engagement for large subsets of the population.
If you get big enough, yes, you’ll be in every channel eventually. But in my experience, businesses diversify across channels way too early. Especially with online channels, the level of competitive has gotten very high. It’s almost impossible to compete at the highest levels on SEO, social, and paid at the same time. Most marketing teams are only good at one channel which subsidizes the rest.
As for what should your sandbox be, you have a few options. The easiest is to start a blog. That’s what this site was started as: a sandbox for learning content marketing, and it only became my full-time job on accident. A blog is a perfect sandbox for learning digital marketing since you can test almost all of the tactics on it, it’s low-cost, and you’ll improve your writing in the process.
