we’re a psychology-based social media marketing company

We’re Obsessed with

Marketing Psychology

Social media is a great way to connect with customers, but it can be hard to know what to post and how often.

With the right social media strategy in place, you can turn your social accounts from an afterthought into a powerful marketing tool that drives sales and helps build your brand.

ST Social Media LLC uses psychological principles like FOMO (Fear of Missing Out) and anchoring to create compelling content that gets people excited about your products or services. We also use psychographics to craft messages based on what’s important to your avatar so they’ll feel more connected and understood by your brand.

Do you ever just go through a creative block where you can’t think of anything new or innovative for your Facebook Ads? I know I do. 

That’s why I personally created a swipe file where I can look through ads I found to be interesting and find inspiration in them to make something awesome for my clients.
