SMM or Social Media Marketing is just as it suggests marketing using your Social Media channels.
How does this work? There are a couple of ways to go about this.
You can either:
a) market your services/products by using your own personal channels to share and spread awareness, or
b) you can create a business page and use paid ads. Like
Facebook ads, or
Instagram sponsored posts (using the correct key-/search words).
I can assist you with either managing your Social Media platforms and getting organic traffic, or I can create beautiful ads that are catered to you, with a clear selling point!
