FAQ ## Online Marketing market size questions ### What must be defined before estimating market size? State the products, customers, geography, time period and revenue measure included. Without that boundary, two correct-looking figures may describe different markets. ### Which inputs are needed when starting from an industry total? It starts with a broader documented total and applies justified shares to reach the target segment. Each source, year and filter should be visible. ### How does a bottom-up estimate differ? It multiplies a count of potential buyers or units by a defensible annual value. The method is useful when the inputs match how the market actually buys. ### Which evidence should support a market-size figure? Prefer current primary statistics, company filings and clearly documented research. Compare definitions and avoid combining numbers simply because they share a topic label. ### What is the difference between TAM, SAM and SOM? TAM describes the broad theoretical opportunity, SAM narrows it to the part a product can serve, and SOM estimates a realistically obtainable share under stated conditions. ### Is market size the same as market share? No. Market size measures the total defined market, while market share measures one company's portion of it. Both require aligned revenue and period definitions. ### How should growth be reported? Show the starting and ending values, dates, currency and formula. Separate measured historical change from a forecast and state whether inflation or exchange rates were adjusted. ### Which assumptions should readers see beside a market estimate? Use a range or scenarios when inputs vary, and identify the assumptions that move the result most. False precision makes a model look firmer than its evidence. ### When should the estimate be refreshed? Refresh it when major source data, product boundaries, prices or market conditions change. Keep previous versions so readers can see why the conclusion moved. ### Can a market-size figure predict revenue for one business? No. Revenue also depends on product fit, capacity, competition, pricing and execution. Market size can frame opportunity, but it cannot guarantee a company outcome.
