Social Media Concepts and Platforms

What the exam tests

The Social Media Concepts and Platforms domain checks whether you can match a business goal to the right platform, explain how distribution works, and use industry vocabulary precisely. Expect items that contrast platform formats, audiences, and native features rather than asking you to memorize logos.

Core rules and concepts

  • Platform families: social networks (Facebook, LinkedIn), microblogging (X), media sharing (Instagram, YouTube, TikTok), messaging (WhatsApp, Messenger), community forums (Reddit, Discord), and review sites (Yelp, Trustpilot). Each carries different intent: LinkedIn skews professional and B2B, TikTok skews entertainment and discovery, Reddit skews topic-specific discussion.
  • Owned, paid, earned media: profile posts are owned; ads and boosted posts are paid; mentions, shares, and reviews are earned.
  • Reach vs impressions: reach is unique people who saw content; impressions are total displays, including repeats. A post can log 10,000 impressions against 4,000 reach.
  • Distribution signals: feeds rank on recency, engagement velocity, predicted relevance, and format fit (watch time for video). Hashtags and keywords aid discovery but cannot rescue weak content.
  • Governance: platforms set minimum ages (commonly 13, with variations), content rules, and advertising policies; brands must satisfy platform terms and local law.

Worked example

A B2B software firm wants demo bookings from IT managers. LinkedIn is the stronger primary channel: its professional graph and job-title targeting support account-based outreach, while TikTok's entertainment context and weaker job-title targeting lower purchase intent. The reasoning chain - audience identity, then intent, then native format (a 60-second demo clip versus a metrics carousel), then measurable conversion - is what exam items reward.

Traps that cost marks

  • Treating reach and impressions as synonyms.
  • Recommending every platform "for awareness" instead of matching goal to audience.
  • Assuming hashtag volume drives reach on every network.
  • Quoting one viral success as a repeatable strategy.
