Getting a good number of social media engagements brings more fulfilment to marketers than simply receiving a high number of page visits. Each time curated content is published, it carries the hope of gaining more engagements.
High engagement means quality content has been valued by readers — earning up to thousands of likes and shares. Engagement refers to any form of interaction within a post or account itself: likes, shares, comments, follows, tweets, emojis, click-throughs, screenshots, and messages. It is a metric in itself.
With billions of social media users across different platforms, catching people's attention is not easy. But on the positive side, reaching out and making multiple connections has become faster and more accessible than ever before.
The Small World Phenomenon
Relating social media to the small world phenomenon — or the six degrees of separation — the theory holds that people are all linked by short chains of acquaintances. Each link is critical in transmitting a message.
The chain in action
A message sent to 10 people, each sharing with 10 more, reaches 15,000+ people in just 6 links.
The principle also implies that as the number of people grows, the smaller the social distance becomes. This explains why friend lists balloon to thousands, and how you often recognise a stranger as "a friend of a friend."
People are hooked to their social media accounts every single day. Marketers should take advantage of this window. With a wide network, good timing, and interesting, relatable content — a post can go viral.
"Viral" is a social media term describing content that spreads like a virus — bringing notable attention and awareness across social media users worldwide. That is every marketer's goal.
Advertising is no longer limited to television, radio, billboards and newspapers. Social media platforms allow you to promote products, communicate anytime, and even post job vacancies — for free, and without limits. Small world phenomenon should be at the core of every business's social media strategy.
12 Ways to Apply the Principle and Drive Engagement
Here is how to take advantage of the small world phenomenon to increase your social media engagement across every platform.
Know Your Audience
Identify who will buy, then master the intricacies of their needs — going beyond demographics to genuine understanding.
Choose the Right Platform
Social media demographics vary significantly by platform. Tailor strategy and content format to where your audience actually lives.
Tag Groups and People
Tagging sparks public conversations. Even if tagged users don't relate to the content, ongoing comments keep it alive in their feed.
Use Hashtags
Hashtags simplify discovery and connect your post to active conversations. They're also useful for sourcing community questions and answers.
Customer Service
Be responsive and personable. Auto-replies disappoint — a helpful, human tone builds loyalty and turns your page into a trusted resource.
Corporate Social Responsibility
CSR content earns deep engagement because people are naturally compassionate. Use your platform to amplify genuine community impact.
Offer Promos
Freebies and discounts attract regular customers — your best word-of-mouth advocates — and expand brand awareness every time they share.
Run Games
Games entertain and exercise the mind. Whether the prize is grand or modest, they reliably expand product visibility and generate buzz.
Share Trivia
Short, surprising facts delight audiences. Consistent trivia builds your page into a reliable source, encouraging follows and return visits.
Conduct Surveys
Surveys signal that you care about your clients' opinions. Loyal customers answer — and results give you direct insight into improvements.
Use Stories
Stories are efficient for busy audiences and humanise your brand — showing the people, places, and everyday moments behind the business.
End with a Question
A well-placed question at the end of an article or infographic invites personal responses and turns passive readers into active commenters.
