Understanding clients and their requirements is important in marketing to produce work they will be pleased with. Communication must be kept open during production and clients should review progress to ensure the work matches their vision. Market research techniques like market segmentation help understand a market's consumers and competition to identify opportunities. A SWOT analysis examines a company's strengths, weaknesses, opportunities, and threats to plan improvements. Audience profiling provides demographic and behavioral information about typical clients to tailor marketing. Press releases aim to communicate newsworthy information to media organizations and should contain the who, what, when, where, why and how of an announcement.
