Core concepts
Market research methods and purposes
Businesses conduct market research to reduce risk when making decisions about new products, pricing, location or promotion. Effective research helps identify customer needs, understand competitors and spot market trends.
Primary research methods:
- Questionnaires/surveys — structured sets of questions distributed to target customers, either online, by post or face-to-face. Cheap for large samples but response rates can be low
- Interviews — one-to-one conversations allowing detailed qualitative responses. Time-consuming and expensive but provide in-depth insights
- Focus groups — small groups discussing products or ideas under moderator guidance. Useful for testing concepts but may not represent wider population
- Observation — watching and recording customer behaviour (e.g., in-store shopping patterns). Provides factual data but doesn't explain motivation
Secondary research sources:
- Government statistics and reports
- Industry publications and trade journals
- Competitor websites and marketing materials
- Market research reports from specialist agencies
- Internal company sales data and customer records
Advantages of primary research:
- Specific to business needs
- Up-to-date and relevant
- Confidential to the business
Disadvantages of primary research:
- Time-consuming to collect
- Expensive, especially for large samples
- Requires expertise to design effective research
Advantages of secondary research:
- Quick to access
- Usually cheaper than primary research
- Often based on large sample sizes
Disadvantages of secondary research:
- May be out-of-date
- Not tailored to specific business needs
- Available to competitors
- Reliability may be questionable
Market segmentation and targeting
Segmentation allows businesses to focus marketing resources on specific customer groups most likely to purchase. This increases marketing effectiveness and return on investment.
Main segmentation methods:
Demographic segmentation — dividing by age, gender, income, occupation, education or family size. Example: Saga Holidays targets over-50s with tailored travel packages
Geographic segmentation — dividing by location, region, climate or urban/rural areas. Example: Caribbean brands like Grace Foods market differently in Jamaica versus UK expatriate communities
Psychographic segmentation — dividing by lifestyle, values, personality or social class. Example: Lululemon targets health-conscious, yoga-practicing consumers
Behavioural segmentation — dividing by purchase patterns, brand loyalty, usage rate or benefits sought. Example: Airlines segment frequent flyers into premium loyalty programmes
Mass marketing versus niche marketing:
Mass marketing targets the whole market with one marketing mix. Advantages include economies of scale in production and promotion, but risks ignoring specific customer needs. Example: Coca-Cola markets globally with similar messaging.
Niche marketing focuses on a small, specific market segment. Advantages include less competition, higher prices and strong customer loyalty. Disadvantages include limited growth potential and vulnerability if the niche declines. Example: Vegan restaurants target plant-based eaters exclusively.
The marketing mix: Product
The product element includes both goods and services, along with features like quality, design, branding and packaging.
Product development involves creating new products or modifying existing ones to meet customer needs. This requires significant investment in research and development but can lead to competitive advantage.
Branding creates customer loyalty and allows premium pricing. Strong brands like Apple or Adidas command higher prices because customers associate them with quality, status or reliability. Brand building requires consistent quality and sustained marketing investment.
Product life cycle stages:
- Development — product designed and tested; no sales yet; high costs
- Introduction — product launched; sales grow slowly; heavy promotion needed; usually loss-making
- Growth — rapid sales increase; competitors enter market; profits rise
- Maturity — sales peak then plateau; market saturated; focus shifts to maintaining market share
- Decline — sales fall due to new technology or changing tastes; business must decide whether to withdraw or attempt extension strategies
Extension strategies prolong profitable product life:
- Product modification (new features, improved formula)
- New packaging or rebranding
- Finding new markets (geographic expansion or new segments)
- New promotional campaigns
- Price reductions to attract price-sensitive customers
The marketing mix: Price
Pricing strategy directly affects revenue, profit margins and market positioning. Businesses must consider costs, competitors, customer perception and business objectives.
Cost-plus pricing — adding a percentage markup to production costs. Simple to calculate and ensures costs are covered, but ignores demand and competition. Commonly used by retailers.
Competitive pricing — setting prices similar to competitors. Appropriate for markets with similar products (e.g., petrol stations) but may trigger price wars reducing profitability.
Penetration pricing — setting low initial prices to attract customers and gain market share quickly. Effective for new products entering competitive markets but requires sufficient scale to be profitable at low margins.
Price skimming — setting high initial prices then gradually reducing them. Used for innovative products with little competition (e.g., new technology). Maximises revenue from early adopters willing to pay premium prices.
Psychological pricing — setting prices slightly below round numbers (e.g., £9.99 instead of £10). Creates perception of better value, commonly used in retail.
Dynamic pricing — varying prices based on demand, time or customer. Used by airlines, hotels and ride-sharing apps to maximise revenue during peak periods.
The marketing mix: Place (Distribution)
Place refers to how products reach customers from manufacturer to final consumer. Effective distribution ensures products are available when and where customers want them.
Distribution channels:
Direct distribution — manufacturer sells directly to consumer with no intermediaries. Example: Dell computers selling online. Advantages include full control and higher margins; disadvantages include high marketing costs and limited market reach.
Indirect distribution — using intermediaries:
- Retailer — sells to consumers (e.g., Tesco, supermarkets)
- Wholesaler — buys in bulk from manufacturers, sells smaller quantities to retailers
- Agent — represents manufacturer, earns commission on sales
Multi-channel distribution combines online and physical stores. Example: Nike sells through own stores, other retailers, and online. Increases market reach but requires coordination across channels.
E-commerce has transformed distribution, allowing businesses to reach global markets without physical stores. Advantages include lower overheads and convenience for customers; challenges include delivery costs, returns handling and competition from established online retailers.
The marketing mix: Promotion
Promotion communicates with potential customers to inform, persuade and remind them about products.
Advertising — paid communication through media channels:
- Television — reaches mass audience, demonstrates products visually, expensive, declining effectiveness among younger demographics
- Radio — cheaper than TV, good for local markets, audio only limits impact
- Print (newspapers/magazines) — can target specific readerships, declining circulation reduces reach
- Online/social media — highly targeted, measurable, cost-effective, increasingly dominant
- Outdoor (billboards/buses) — high visibility in specific locations, limited message detail
Sales promotion — short-term incentives encouraging purchase:
- Money-off coupons
- Buy-one-get-one-free (BOGOF)
- Competitions and prize draws
- Loyalty cards and points schemes
- Free samples
Effective for boosting short-term sales but can damage brand image if overused and may simply shift timing of purchases rather than increase overall demand.
Public relations (PR) — building positive image through media coverage, sponsorship, charity work and community involvement. Cost-effective but harder to control than paid advertising.
Personal selling — face-to-face interaction between salespeople and customers. Essential for complex or expensive products (cars, insurance) but expensive per customer contact.
Digital marketing:
- Social media marketing — engaging customers through platforms like Instagram, TikTok, Facebook
- Search engine optimisation (SEO) — improving website visibility in search results
- Email marketing — sending targeted messages to customer lists
- Influencer marketing — partnering with social media personalities to reach their followers
Worked examples
Example 1: Market research decision (4 marks)
Question: Explain two reasons why a business launching a new product might use primary research rather than secondary research.
Answer: Primary research provides information specific to the new product (1), which is important because existing secondary data won't cover a product that doesn't yet exist (1). Primary research also remains confidential to the business (1), preventing competitors from knowing about the new product plans and potentially copying the idea (1).
Mark scheme notes: 2 marks per reason — 1 for identification, 1 for development/explanation in context.
Example 2: Marketing mix analysis (6 marks)
Question: Analyse how a premium smartphone manufacturer might use two elements of the marketing mix to increase sales.
Answer: The manufacturer could use price skimming as a pricing strategy (1). By setting high initial prices when launching new models, they can maximise revenue from early adopters who want the latest technology (1). This works for premium brands because customers perceive high prices as indicating superior quality (1).
They could also use promotion through social media influencers (1). Technology influencers reviewing and demonstrating the smartphone's features reach millions of potential customers (1). This is particularly effective for smartphones as the target market of younger consumers actively uses social media platforms and trusts influencer recommendations (1).
Mark scheme notes: 2 elements × 3 marks each. Requires identification, explanation and application to context.
Example 3: Product life cycle application (8 marks)
Question: Recommend whether a soft drinks company should use extension strategies for a product in the decline stage or develop a completely new product. Justify your recommendation.
Answer: Extension strategies could work if the decline is due to temporary factors. The company could redesign packaging to make it more appealing (1) or add new flavours to attract different customer segments (1). This would be cheaper than developing a new product from scratch (1). However, if decline is due to changing consumer preferences toward healthier drinks, extension strategies may only delay the inevitable (1).
Developing a new product allows the company to meet current market demands (1), such as creating a low-sugar or natural ingredient version (1). This addresses the root cause of declining sales rather than just slowing the decline (1). However, new product development is expensive and risky, with many new products failing (1).
Recommendation: Develop a new product because the soft drinks market is shifting toward health-conscious options (1). Extension strategies would waste resources on a product no longer meeting customer needs (1). Although risky, a new product aligned with health trends has better long-term profit potential (1).
Mark scheme notes: For 8 marks, expect 6-7 developed points plus justified recommendation. Must weigh both options and apply business context.
Common mistakes and how to avoid them
- Confusing primary and secondary research — Remember: primary is new, first-hand data you collect yourself; secondary already exists, collected by others. Don't say "primary research is more reliable" without explaining why
- Listing features instead of benefits — When discussing products, explain how features meet customer needs, not just what the features are. Example: "waterproof case (feature) protects phone in rain, giving peace of mind (benefit)"
- Ignoring context in marketing mix questions — Always apply answers to the specific business described. A luxury car manufacturer and a budget airline need very different marketing mixes
- Treating all promotion methods equally — Different promotional tools suit different products, budgets and target markets. Television advertising suits mass-market products with large budgets; social media suits businesses targeting younger demographics cost-effectively
- Forgetting to justify recommendations — Questions asking you to "recommend" require weighing advantages and disadvantages of options before stating which is best and why
- Defining terms without application — Don't just define "market segmentation" — explain how a specific business could use it and what benefits it would gain
Exam technique for "Marketing"
- Command words matter: "State" requires brief answers (1 mark each). "Explain" needs a point plus development (2 marks). "Analyse" requires detailed examination with context (3+ marks per point). "Evaluate/Recommend/Justify" demands weighing options and reaching a supported conclusion (typically 8-12 marks)
- Use business context: Generic answers score poorly. If the question mentions "a Caribbean hotel chain," reference tourism patterns, local competition, or regional market characteristics
- Structure longer answers: For 6+ mark questions, use clear paragraphs for each point. Start with a topic sentence, develop with explanation, apply to the context
- Show both sides for evaluation: Before recommending a pricing strategy or promotional method, acknowledge advantages AND disadvantages. Examiners reward balanced analysis before your conclusion
Quick revision summary
Marketing helps businesses identify and meet customer needs profitably. Market research (primary and secondary) reduces decision-making risk. Market segmentation divides markets into groups with similar characteristics. The marketing mix combines product (what's sold), price (what customers pay), place (distribution channels) and promotion (communication methods) to achieve marketing objectives. Products pass through life cycle stages requiring different strategies. Successful marketing requires understanding customer needs, competitor actions and market trends, then deploying appropriate marketing mix elements.
