One of the biggest mistakes a marketer can make is trying to market a product to everyone. A strong marketing plan starts with understanding exactly who the target customer is, where they are located, what they are interested in, and what influences their decisions. Two tools that can help marketers define a target market are the U.S. Census Bureau’s Census Business Builder and Google Trends. These tools provide different types of information, but when they are used together, they can help create a much clearer picture of the customer.

The first tool I would recommend is Census Business Builder. This tool provides demographic, economic, and socioeconomic information that can help marketers understand people within a specific geographic area. Marketers can research information such as population, age ranges, household characteristics, income levels, and other characteristics that may affect buying behavior. The Census Bureau also allows users to research industries and compare geographic areas, which can be useful when deciding where a product or service may have the strongest market opportunity (U.S. Census Bureau, 2026).

This information is important when developing a marketing plan because it helps marketers move beyond assumptions. For example, if a company is introducing a product designed primarily for young professionals, Census Business Builder could help identify areas with larger populations within that age range and provide additional information about income and household characteristics. A marketer could then use this information to determine which geographic markets should receive the most advertising attention. The Census Bureau even recommends using its data to identify target customers, research competitors, and evaluate potential business locations (U.S. Census Bureau, 2026).

The second tool I would recommend is Google Trends. While Census Business Builder helps explain who customers may be, Google Trends can provide insight into what people are actively interested in. Google Trends uses aggregated Google search data to show how interest in a particular search term or topic changes over time and across different geographic areas (Google, n.d.). Marketers can compare multiple topics, identify increases or decreases in interest, and examine where certain subjects are receiving the most search activity.

Google Trends could be especially valuable when marketers are trying to understand customer interests or determine whether demand for a product is increasing. For example, a company considering a new fitness product could compare search interest for different types of workouts or fitness equipment. If one topic shows stronger or growing interest, the company could use that information when deciding which product features to emphasize in advertising. Google Trends also allows marketers to compare current search behavior with earlier periods, which can help identify seasonal patterns or changing customer interests (Google, n.d.).

I think the strongest approach would be to use both tools together rather than relying on only one. Census Business Builder could help define the demographic and geographic characteristics of the target customer, while Google Trends could help identify what those customers may currently be searching for or interested in. For example, Census data might show that a certain market has a large population of consumers within the company’s desired age and income range, while Google Trends could show whether people in that area are demonstrating interest in the type of product being offered.

The information collected from these tools can affect several parts of a marketing plan. It can influence the target market, positioning strategy, advertising message, communication channels, geographic focus, and even pricing decisions. Instead of creating a broad marketing campaign and hoping it reaches the right people, marketers can use research to make more focused decisions.

If I were giving advice to someone who was new to marketing, I would say that defining a target market should involve both numbers and behavior. Demographic information can tell marketers who potential customers are, while tools such as Google Trends can provide clues about what those customers are currently interested in. Combining both types of information can create a stronger foundation for a marketing plan and help businesses make decisions based on evidence instead of guesses.
