Market share represents the percentage of total sales a company captures in a specific market or product category. It can be measured in terms of units sold (volume) or total revenue (value). For example, if a brand sells 30 out of every 100 items in its category, it has a 30% market share.

A company’s market share is a key indicator of competitiveness and growth potential. High market share suggests strong consumer preference, efficient distribution, and effective marketing. Conversely, declining share may signal increasing competition or changing customer needs.

Companies often track market share to measure success, evaluate strategies, and identify opportunities for expansion. Maintaining or growing share requires continuous innovation, strong branding, and a customer-first approach.
