Definition:

Market share measures the proportion of a defined market that a company controls, typically expressed as a percentage of total category sales, volume, or revenue. It is one of the most widely used indicators of competitive health, helping brand, strategy, and insights teams assess whether growth is outpacing the category or simply riding a rising tide. Understanding market share requires both quantitative tracking and qualitative depth: the numbers show movement, but customer research reveals the attitudes, perceptions, and unmet needs that drive it. For enterprise teams, connecting market share data to real customer understanding is what separates a diagnosis from a decision.

How Conveo Does It

Conveo helps enterprise teams understand the customer attitudes and perceptions that sit behind market share shifts, using AI-moderated video interviews that launch in under 30 minutes and return findings in days. Every session involves real participants, not synthetic respondents, so the understanding traces back to actual voices. At scale across 50 or more markets and languages, teams can probe why share is moving, which competitors are gaining consideration, and what it would take to shift preference, while the decision window is still open.

Frequently asked questions.

Market share is the percentage of a defined market that one company or brand accounts for, measured by sales volume, revenue, or unit count over a set period. It is calculated by dividing a company's sales by total category sales and multiplying by 100. The definition of the market boundary matters considerably: a brand can hold strong share in a narrow segment while appearing marginal in a broader category definition.
Market share data tells teams that competitive position has changed, but it rarely explains why. Insights and research teams are responsible for closing that gap, connecting the movement in share to the customer attitudes, brand perceptions, and purchase drivers that caused it. Without that qualitative layer, share data is a lagging indicator that arrives too late to inform the next campaign, product decision, or pricing call. Research gives the number a cause.
Market share measures actual commercial performance, the proportion of category sales a brand captures. Share of voice measures advertising or media presence, the proportion of total category spend or impressions a brand accounts for. The two are related but distinct: a brand can hold high share of voice while losing market share if its messaging is not resonating, or hold strong market share with relatively low media investment if loyalty and word of mouth are doing the work.
AI-moderated research makes it practical to run continuous, large-scale qualitative studies that track the customer attitudes driving share movement, rather than waiting for a quarterly agency debrief. Teams can probe switching behavior, competitor perceptions, and unmet needs across multiple markets simultaneously, with analysis completing as conversations close. The result is that market share shifts can be investigated and understood while there is still time to respond, rather than after the next tracking wave confirms the trend.
Enterprise teams use qualitative research to identify the specific perceptions, unmet needs, and competitive vulnerabilities that are moving market share before the numbers confirm the shift. This includes concept testing to validate whether new products address real gaps, brand perception studies to understand how positioning compares to rivals, and customer exit research to learn why buyers switched. Running these studies continuously, rather than as one-off projects, means teams build a compounding picture of what drives share in their category.
