Social media refers to online platforms and apps where people create profiles, publish and share content, and interact with one another through posts, comments, reactions and messages. The related term social network emphasizes the connections between users, such as followers and friends.
Why it matters
Social media is a main route by which people discover news, products and sites. For website owners it is a traffic source, a customer service channel and a place where brand reputation forms quickly. Platforms control reach through their own recommendation systems and rules, which can change without notice, so relying on one platform alone is risky.
Example
A shop posts a product photo with a link in its profile. Followers like and share it, the platform's feed shows it to people who do not follow the shop, and visitors arrive at the product page. Adding UTM parameters to the link lets analytics show how many came from each platform.
Common mistakes
- Building an audience only on a platform you do not control, with no email list or website of your own.
- Treating followers as customers. Reach and sales are different measures.
- Posting personal details publicly without checking privacy settings.
