Marketing involves market research, analysis, and strategy. Market research provides knowledge about competitors, prices, and customer preferences. Market analysis collects data on trends, growth, strengths, and threats. Marketing strategy allows companies to budget and focus on a singular attainable goal like TESCO's strategy of small price reductions. Advertising creates brands and trust while brand promotion reinforces brands through sponsorships.
Public relations principles include consistent messaging to build trust. Positive publicity shows companies in a good light while spin frames issues positively. Damage limitation protects company image when threatened. Events and lobbying influence consumers and government respectively, with lobbying most impacting policies.
