What MKTG90042 covers

Eight chapters follow the published topic sequence from platform foundations to campaign governance.

01

Platforms, Zones and Marketing Objectives

Platform affordances, social zones, marketing objectives and measurable participation.

Social media marketing begins with a distinction that is easy to blur under exam pressure. A platform is not simply a traditional channel moved online.

  • Platform affordances and networked participation
  • Community, publishing, entertainment and commerce zones
  • Business problems, audience outcomes and marketing objectives
  • Exposure, interaction and behavioural measures
02

Social Consumers, Segments and Personas

Segmentation, targeting, social identity, digital footprints and evidence-based personas.

Social consumers leave traces of interests, relationships and behaviour, but a trace is not automatically an insight. The analytical task is to decide which differences matter for the marketing problem.

  • Segmentation variables and target evaluation
  • Social identity and digital footprints
  • Persona evidence, goals and frictions
  • Research uncertainty and stereotype control
03

Virality, Word of Mouth and Firestorms

Transmission, share motives, online communities, amplification and firestorm response.

Virality is a pattern of person-to-person transmission, not a synonym for high view count. A piece of content can receive heavy paid distribution without spreading through social ties.

  • Digital word of mouth and transmission
  • Share motives and social context
  • Paid, owned and earned amplification
  • Firestorm diagnosis and response
04

Influencers and Social Network Analysis

Influencer selection, network ties, centrality measures, density and campaign fit.

Influence is the capacity to affect attention, interpretation or behaviour within a social setting. Follower count is therefore only one clue.

  • Nodes, edges and network communities
  • Degree and betweenness centrality
  • Closeness, eigenvector centrality and density
  • Influencer fit, disclosure and measurement
05

Strategy, Funnels and Campaign Measurement

Strategic planning, funnel stages, objectives, indicators and review decisions.

Strategy turns a business problem into coordinated choices. The course's planning sequence moves from situation analysis through goals, audience, social media mix, experience strategy and activation to execution and measurement.

  • Situation analysis and objective setting
  • Audience, mix and experience strategy
  • Funnel stages and indicator choice
  • Outputs, responses and business outcomes
06

Tactical Plans, Channels and Content

Channel roles, experience design, content plans, editorial calendars and governance.

A tactical plan converts strategy into coordinated action. It explains why the audience should care, where the experience will occur, what content supports it, how material will be produced and promoted, and who owns each decision.

  • Value-driven tactical planning
  • Channel roles and experience design
  • Content plans and editorial calendars
  • Ownership, approval and contingency
07

Advertising, Commerce and Social Experiences

Advertising, commerce, community, publishing and entertainment as participation modes.

Later weeks move across advertising and commerce, community, publishing and entertainment. The analytical task is not to memorise isolated techniques.

  • Targeted social advertising
  • Discovery, evaluation and social commerce
  • Community and publishing experiences
  • Entertainment, participation and attribution
08

Ethical and Legal Campaign Decisions

Stakeholder harm, transparency, data use, claims, safeguards and escalation.

Ethical and legal issues are not a final compliance paragraph added after a campaign is designed. Data use, targeting, creator relationships, moderation and persuasive design shape the campaign from the first decision.

  • Stakeholders, benefits and burdens
  • Data, targeting and persuasive design
  • Claims, disclosure and less intrusive alternatives
  • Approval, monitoring and escalation

The subject connects platform and community structure to practical strategic decisions.

The final examination uses a case study and open-ended questions, so this guide emphasises application. Each chapter moves from a concept map to a fresh decision case and a boundary clinic.

Quantitative sections retain explicit denominators for centrality and campaign rates, while qualitative sections distinguish observed evidence from inference.

The organising question is what evidence supports the proposed audience change, through which mechanism, and how the organisation would know whether the action worked.

Platform features, personas, creator partnerships and campaign metrics matter only when they answer part of that decision chain. A large number is therefore a starting observation rather than a verdict.

Revision should join the early and later weeks.

Consumer evidence shapes targeting; transmission and network structure shape distribution; strategy defines the outcome; tactical planning coordinates delivery; the social zones provide different participation modes; and ethical review constrains data, claims and persuasive design. This connected map prevents isolated framework lists in an integrated case.

Assessment practice should mirror the published formats.

Rehearse short calculations with explicit denominators for the mid-semester test, research-supported strategic and tactical recommendations for the group assignment, and integrated case reasoning for the final examination. Keep operational dates separate from conceptual revision and verify them on the official subject systems.

Choose a measure for a campaign objective

Q [4 marks]. A campaign receives 18,000 impressions, 540 clicks and 81 completed registrations. Calculate click-through and registration-per-click rates, then identify what each rate shows.

Social experiences. The sequence organises the decision without guaranteeing the outcome for this social experiences map.
  • 1Click-through rate = 540 divided by 18,000 multiplied by 100 = 3%.
  • 1Registration-per-click rate = 81 divided by 540 multiplied by 100 = 15%.
  • 1The first rate describes movement from delivered impressions to clicks; it does not prove attention or persuasion.
  • 1The second describes movement from clicks to completed registrations; compare both with a baseline before judging success.
CTR is 3% and registration per click is 15%. They diagnose different stages and require a comparison for evaluation. Practice weighting is assigned by AskSia; the University has not published this split.
Sia tip — Write the denominator beside every rate before interpreting it.

FAQ

MKTG90042 FAQ

How is the subject assessed?

The published structure combines seminar preparation and participation, a mid-semester test, a group assignment and an end-of-semester examination. Their weights are 10%, 20%, 30% and 40%, which total 100%. Each component assesses a different kind of preparation or application.

What is the final examination format?

The subject materials describe a two-hour closed-book examination with reading time. It uses one case study and open-ended questions, covers the subject and places particular focus on material from Week 7 onward.

Does the subject include calculations?

Yes. The mid-semester test may include simple calculations, and the teaching materials cover network centrality and campaign rates. Show the denominator, compute the value and explain what the result can support.

How should I build a useful persona?

Begin with research about the target context, goals, frictions and behaviour. Separate observed evidence from assumptions, translate the pattern into message and channel implications, and record uncertainty that further research could resolve.

Is a popular post automatically viral?

A large view count can come from paid delivery, media coverage or platform recommendation. Virality concerns person-to-person transmission, so inspect sharing pathways, reshare depth and community context before using the label.

Which centrality measure should I use?

Choose from the decision: degree for direct connection, betweenness for brokerage, closeness for network access and eigenvector centrality for links to influential nodes. Then add audience fit and credibility checks.

What makes a campaign strategy defensible?

A defensible strategy traces a clear chain from business problem and audience to objective, experience, channel role, measure and review condition. Each tactical choice should have a distinct job within that chain.

Is this an official University guide?

This is an independent AskSia study resource grounded in university-derived materials. Confirm live dates, submission settings and examination instructions on the official subject systems before relying on them.

Chapter questions

Questions students ask in each MKTG90042 chapter

How do I choose a social platform?
Start with the business problem, audience and desired change. Select the zone and affordance that support that change, then choose a platform whose audience use and measurement options fit the decision. Chapter 01 · Platforms, Zones and Marketing Objectives
What makes a persona useful?
A useful persona is built from more than one evidence source, focuses on facts relevant to the marketing decision, and changes a message, experience or channel choice while recording important uncertainty. Chapter 02 · Social Consumers, Segments and Personas
Is a high view count evidence of virality?
Not by itself. Views may come from paid delivery, media embedding or platform recommendation, so inspect reshare paths, transmission depth and the community context before claiming person-to-person diffusion. Chapter 03 · Virality, Word of Mouth and Firestorms
Does the most connected account make the best influencer?
No. Degree measures direct ties, but the objective may require brokerage, network access or prestige instead. Any structural score also needs checks for audience overlap, credibility, activity and creative fit. Chapter 04 · Influencers and Social Network Analysis
Which campaign metric should I report?
Choose the metric that directly reflects the stated audience outcome, keep its denominator visible, and add a baseline or comparison. Report outputs, audience responses and business outcomes as separate layers. Chapter 05 · Strategy, Funnels and Campaign Measurement
What belongs in a tactical plan?
A tactical plan names the audience value, channel roles, content and experience, production and publishing sequence, promotion, community response, owners, dependencies, measures and a contingency for likely failure. Chapter 06 · Tactical Plans, Channels and Content
Should a campaign use every social zone?
No. Add a zone only when it performs a distinct audience job and has a matching measure. A smaller connected experience is stronger than a broad tactic list with duplicated roles. Chapter 07 · Advertising, Commerce and Social Experiences
Is clear disclosure enough for an ethical campaign?
No. Disclosure can improve transparency but cannot repair a misleading claim, unsuitable audience, excessive data collection or harmful design. Review the entire decision and choose less intrusive alternatives where available. Chapter 08 · Ethical and Legal Campaign Decisions
Study strategy

How to study for the exam

Build a one-page map of the eight chapter decisions, then practise converting fresh case evidence into a mechanism, recommendation, measure and boundary. Recompute every network or campaign rate with its denominator visible. In the final pass, rehearse one integrated case under the published two-hour closed-book format and check current operational instructions on the official subject systems.
