From Testimonials to TikTok: The Evolution of User-Generated Content

Before there was TikTok, there were infomercials. Before infomercials, there were newspaper ads. And before all of that, there was the oldest form of marketing in the world: one person telling another person about something that worked for them.

UGC isn't new. The format has just changed.

Understanding how we got here helps you understand why UGC works so well today, and how to use it properly in your business.

It Started With Word of Mouth

For most of human history, the way people found out about products was simple. Someone they trusted told them about it.

Your neighbour recommended a butcher. Your colleague suggested a doctor. Your friend told you about a shop with great prices.

This kind of recommendation carried enormous weight. It still does. The difference is that word of mouth used to stay local. Now it scales.

The First Wave: Written Reviews

When the internet arrived, word of mouth moved online. People started leaving reviews on websites, forums, and eventually platforms like Google and Hellopeter.

For the first time, a single customer's opinion could reach thousands of strangers. Businesses that had great reviews thrived. Businesses that ignored their online reputation paid for it.

This was the first real form of digital UGC, and it changed consumer behaviour permanently. Studies today show that most people read online reviews before making a purchase. That habit was formed in this era.

What brands should take from this: Reviews are still UGC. If you're not actively encouraging satisfied customers to leave reviews, you're leaving trust on the table. Make it easy. Send a follow-up message after purchase. Include a QR code on your packaging. Ask.

The Second Wave: Photos and Lifestyle Content

Instagram changed everything when it launched in 2010. Suddenly, real people were sharing photos of their meals, their outfits, their homes, and the products they loved.

Brands quickly realised that when a customer posted a photo with their product, it reached that customer's entire network. It felt authentic because it was. It wasn't a billboard. It was someone's life.

Smart brands started reposting customer content, creating branded hashtags, and encouraging their communities to share. This became a core part of social media marketing strategy.

What brands should take from this: Your customers are already creating content about your brand. Are you paying attention? Search your brand name on Instagram and TikTok right now. What comes up? That content is an asset. Engage with it, repurpose it, and build on it.

The Third Wave: Video and the Creator Economy

Then came YouTube, then TikTok, then Reels. And everything shifted again.

Video is the most powerful format for building trust quickly. Watching someone use a product, hear their tone of voice, see their genuine reaction, that is far more convincing than any written review or lifestyle photo.

At the same time, a whole economy of content creators emerged. These aren't celebrities. They're regular people who happen to be good on camera, relatable, and skilled at creating short video content that holds attention.

This is where we are now. And this is where UGC becomes a proper business tool, not just a nice-to-have.

What brands should take from this: You no longer need a film crew to produce effective video content. You need the right creators, a clear brief, and a platform that connects you to both. The brands growing fastest right now have figured this out.

Where UGC Is Going Next

The next shift is already happening. It's about scale and consistency.

In the past, working with UGC creators was messy. Brands had to find creators themselves, negotiate individually, manage payments manually, and hope the content was good. It was slow and unpredictable.

Now, platforms exist that bring structure to the whole process. Verified creators. Clear briefs. Algorithmic matching. Structured feedback. Automated payments. UGC is becoming as reliable and repeatable as any other marketing channel.

For South African brands, this is a real opportunity. The local creator economy is growing fast, costs are lower than in the US or UK, and the audiences are highly engaged.

The Throughline From Then to Now

Every wave of UGC, from word of mouth to written reviews to photos to video, has worked for the same reason. People trust people.

The format changes. The psychology doesn't.

Your job as a brand is to make it easy for real people to tell your story well. Give them the right information. Give them the right product. Give them a clear brief. And then let them do what they do best: be human.
