Learn how to conduct effective secondary research with proven methods, reliable sources, and analysis techniques. Save time and resources today.

What Is secondary research & how can it benefit your work?

Secondary research involves gathering information that someone else has already compiled, offering a way to understand trends, benchmarks, and the context behind your subject matter without starting from scratch. It stands in contrast to primary research, where you generate new data through experiments, surveys, or interviews. Familiarizing yourself with secondary data sources can save you time, yet it comes with its own challenges—like sifting through vast amounts of information and ensuring the data's credibility. Knowing when to use secondary research rather than primary techniques is key, especially when resources or time are limited. With clear steps and reliable sources at your disposal, you can effectively use secondary research to support your projects.

Let's explore the process and best practices for conducting meaningful secondary research.

What is secondary research and how does it differ from primary research?

Ever wondered why some product launches succeed while others flop? The answer often lies in research quality. Secondary research—the analysis of existing data collected by others—plays a crucial role in CPG product development, but it functions quite differently from primary research.

Secondary research involves gathering and analyzing data that already exists. Think published market reports, academic studies, government statistics, competitor analysis, and industry publications. Unlike primary research, you're not collecting fresh data directly from consumers.

Here's how they compare:

Aspect	Secondary Research	Primary Research
Data source	Pre-existing information collected by others	New data collected directly from subjects
Cost	Generally lower cost	Often higher cost (recruiting, incentives, etc.)
Time required	Faster to obtain	Typically takes longer to plan and execute
Control	Limited control over data collection methods	Full control over methodology and questions
Specificity	May not address exact research questions	Tailored precisely to research needs
Examples	Market reports, academic papers, government data	Surveys, focus groups, interviews, product tests

Secondary research serves as an excellent starting point for understanding market landscapes, identifying trends, and forming hypotheses. For CPG professionals, it provides context before investing in more expensive primary research.

A balanced approach often works best: use secondary research to understand the broader market and identify opportunities, then conduct targeted primary research to validate specific product concepts or claims with your exact audience.

How to find reliable sources for secondary research

Can you trust that industry report you just downloaded? Finding credible secondary research sources is perhaps the most critical step in your research process. Without reliable data, even the most sophisticated analysis will lead to faulty conclusions.

The quality of your secondary research depends entirely on the sources you choose. For CPG professionals, here are the most dependable places to find trustworthy data:

Academic and peer-reviewed sources:

• Academic journals in consumer behavior, food science, or marketing

• University research centers focused on consumer goods

• Peer-reviewed studies published in respected publications

Industry-specific resources:

• Nielsen, IRI, and SPINS retail data

• Mintel and Euromonitor market reports

• Trade associations like Consumer Brands Association or FMI

Government and regulatory sources:

• FDA regulations and guidance documents

• USDA agricultural and consumer data

• Census Bureau demographic information

• Bureau of Labor Statistics consumer spending data

Commercial research providers:

• McKinsey & Company industry reports

• Forrester and Gartner market analyses

• IBISWorld industry profiles

When evaluating a source's reliability, ask yourself these questions:

• Who created this information and what's their expertise?

• When was it published or last updated?

• What methodology did they use to collect the data?

• Does the source have any potential biases or conflicts of interest?

• Is the information consistent with other reputable sources?

Remember that even the most trustworthy sources have limitations. Cross-reference important findings across multiple sources to build a more complete picture of your market.

Step-by-step process for conducting secondary research

Ready to start your secondary research journey? Following a structured approach ensures you'll gather comprehensive insights while avoiding common pitfalls. Here's a systematic process that CPG professionals can follow to conduct effective secondary research:

   • Categorize data by topic, source, and relevance

   • Note any contradictions or gaps in the available information

5. Analyze and interpret the data

   • Look for patterns and trends across multiple sources

   • Identify how findings relate to your specific research questions

   • Consider how recent events might impact historical data

   • Note limitations of the research you've gathered

6. Synthesize insights

   • Connect dots between different data points

   • Draw conclusions based on the collective evidence

   • Identify implications for your product or strategy

   • Determine what questions still need primary research

7. Document and share

   • Create a clear summary of key findings

   • Include source citations for all data

How to manage your time while conducting secondary research

Is your research project expanding beyond its timeline? Secondary research can quickly become a bottomless pit that consumes hours without yielding proportionate insights. Effective time management ensures you extract maximum value without endless searching.

Time is perhaps your most precious resource when conducting secondary research. Here's how to use it wisely:

Start with a time budget

• Allocate specific hours for each research objective

• Set calendar blocks dedicated solely to research activities

• Create milestones to track progress against your timeline

Prioritize your sources strategically

• Begin with high-yield sources that typically provide the most relevant information

• Focus on industry-specific reports before general business publications

• Review recent studies before older ones (unless establishing historical trends)

• Save social media analysis for after reviewing more substantive sources

Use the "funnel approach"

• Start broad to understand the market landscape (1-2 hours)

• Narrow to category-specific information (2-3 hours)

• Focus on your specific product type or consumer segment (3-4 hours)

• Finish with competitor analysis (2-3 hours)

Implement practical time-saving techniques

• Use advanced search operators to find specific information quickly

• Create templates for note-taking to standardize your process

• Set a timer when reviewing lengthy reports to maintain focus

• Bookmark promising sources for later rather than going down rabbit holes

• Use research tools like Zotero or Evernote to organize findings as you go

Know when to stop

• Establish clear "good enough" criteria before starting

• Watch for diminishing returns (when new sources repeat information)

• Schedule brief review sessions with colleagues to validate findings

• Recognize when questions would be better answered through primary research

Remember that perfect information doesn't exist. The goal is gathering sufficient insights to make informed decisions, not becoming an absolute expert on every market nuance.
