Top 6 Principles of Viral Spread

Public visibility here refers not only to promoting a product to consumers, but also to the rapid and natural spread of the product itself. Once the initial step is taken, the product will gain the power to self-advertise to the public. A prime example is Coca-Cola's successful campaign of printing names on their cans. When someone personalized their can and shared a photo on social media, others found it fun and followed suit. Coca-Cola connected its brand with consumers in a very organic and personal way. Similarly, Sunsilk shampoo boosted its public visibility by creating animated chibi characters based on photos from customers using Sunsilk, making people excited to see their image associated with the brand in a fresh and innovative way. The key takeaway is that when done cleverly, public visibility requires less effort while reaching a wider audience.

Practical value refers to presenting your product information in the most concise, useful, and easy-to-understand way for your customers. In a sea of choices, you need to make your product message stand out. This standout appeal comes from highlighting convenience, such as saving time, money, and effort. For example, using a water purifier saves time on boiling water, and using Pigeon bath and body products saves both money and time for mothers. Convenience and savings spread the fastest through word-of-mouth. The key is to emphasize the exceptional value your product brings to the customer. Practical value is what customers will immediately notice when they use your product.

People don’t just share information—they tell stories. Product information easily becomes part of everyday conversations. Women chat about beauty products, food, and family-related items, while men discuss work, solutions to problems, and stress relief. So, how do you weave your product into these stories through advertisements or viral content on social media?

In today’s digital age, social media is the most powerful tool for spreading messages. People become more aware of products when a famous celebrity talks about the trust they have in a product’s effectiveness, or when a popular figure like Sơn Tùng endorses a brand like Oppo, causing a spike in phone sales. The stories you create can be limitless, but they need to be purposeful and aligned with the right direction.

Triggers are the moments when people mention your product while discussing ideas or other related products. For instance, when you think of chicken, you immediately think of kaffir lime leaves—this is how triggers work. When people mention your product, it means it’s top of mind for them, often becoming the first choice when they make decisions. For example, when it comes to men's shower gels and shampoos, the first brand that comes to mind is often X-Men, followed by others. Similarly, if someone is planning a trip to Vietnam, Da Nang might be the first recommendation due to its reputation as the most livable city.

Appealing to emotions is the fastest way to connect your product with customers. Recently, consumers were confused about which fish sauce to trust after reports of arsenic contamination in many brands. Once traditional fish sauce was confirmed to be safe, consumers quickly turned back to it, even boycotting industrial fish sauces. This created a sense of reassurance for the customers. Similarly, miraculous pimple removal products advertised on Facebook with a 30-second video created surprise and trust, leading many to purchase immediately.
