What is Market Research?

Market Research can be defined as an attempt at understanding consumer behavior. This involves gathering data systematically about people or companies – a market – and then analyzing it to better understand the needs of that group of people/companies.

This type of research can be undertaken by the company itself (i.e. in-house) or by a third-party agency specialized in market research.

Market Research Companies

Advantages of conducting business market research include:

Identify problem areas in business.
Identify changing market trends and associated business opportunities as well as new areas for expansion.
Understand the existing customer’s needs and comparative analysis of services offered to customers vis-à-vis competitors.
Develop effective strategies and make well-informed decisions about the services.
Set achievable targets for sales, business growth, and the latest product developments.

There are two types of market research: Qualitative research and Quantitative research.

Qualitative research is focused on descriptive words and symbols. It usually involves questioning consumers about their product or service consumption experiences or observing them in a marketing setting. The data collection methods used in this case include in-depth interviews, focus groups, bulletin boards, uninterrupted observation, and ethnographic participation/observation.
Quantitative research is the one that looks to quantify a problem which often involves statistical analysis since it requires significant attention to the measurement of market phenomena. It collects data through audits, points of purchase (purchase transactions), surveys in different modalities (online, phone, paper), and click-streams.

The two ways through which data is collected include Primary Data and Secondary Data.

Primary data is the original data that is collected firsthand by the researcher. The most common primary research tools are surveys, focus groups, in-depth interviews, and observation.
Secondary data is the data that has already been collected and is readily available. This data is pre-existing public information, for instance, the data shared in public sources like magazines and newspapers, government statistics; commercial sources like paid industry reports; and internal sources i.e. the market data that the organization already has in-house.

The procedures that are used to analyze the data collected include (but are not limited to) product testing, market segmentation, advertising testing, usability testing, key driver analysis for loyalty and satisfaction, awareness and usage research, and pricing research (using techniques such as conjoint analysis).

Types of Market Research Companies

Market research companies can be large corporate companies, small business companies, or product-specific companies. These companies are usually categorized based on clients they take up rather than based on market research work they undertake.

#1) Syndicated market research firm: Such companies look at the market requirements and then prepare their reports accordingly. These research reports are for the open market rather than for specific companies.

#2) Custom market research firm: Such firms offer customized market analysis basis for the client’s needs.

#3) Specialty market research firm: A firm with a focus on one specialty falls under this category. Such firms are involved with an in-depth analysis of the client’s specific requirements, for instance, conducting market feasibility studies for a soon-to-be-launched pilot product.

#4) Online market research firm: These firms are considered to be useful for online marketers, bloggers, and online e-commerce portals. They connect the brands/website owners with their desired users while also conducting online analysis at the same time.

This online analysis enables the website owners to land on top in search engines, understand the gist of their brands in the online community, and thereby improvise their existing product lines. Brands, for instance, take a cue from the ‘trends’ showcasing top websites like Twitter and Facebook.

Expert Advice: Once the said company has decided to hire a market research firm, the following factors need to be considered before choosing the one:

The extent of understanding of its sector by the market research firm.
Capabilities of the market research firm – qualitative/quantitative/both.
Timelines expected by the company vs. promised by the firm.
A clear understanding of the company’s research objectives and methods to be used by them – focus groups vs. survey vs. secondary search.
The company’s scale of project and affordability as a market research agency usually does not takes on projects with a budget below £3,000. So, for small-scale field research, the best option may be a freelance researcher.
Cost calculations as a majority of market research firms charge per hour. However, researching the published material is considered easier than conducting focus groups and surveys.

FAQs For Market Research Firms

1. Which is the best methodology for undertaking Market Research?

Depending on the needs and objectives of the market research, i.e., measuring or exploring, the company can choose between focus groups and in-depth interviews as part of a qualitative approach or online surveys as part of a quantitative approach.

2. Should the research be done in-house or get expert help?

The first question that arises once a company has decided to undertake market research is whether to conduct the study in-house or do it using third-party help. While hiring a third-party market research firm ensures confidentiality (for surveyed customers) and expertise it increases the overall cost allocated for a project.
The ideal solution therefore of hiring a market research firm or not boils down to the cost/benefit analysis. Once the company is aware of its research budget, which as per Philip Kotler, is 1-2 percent of company sales, it can compare the cost of hiring a marketing research firm with the cost of paying one or more of its employees to do the work.
The end objective of the study should also be kept in mind.

3. How much does market research cost?

Costs vary greatly depending on the scope and methodology. A professional survey usually starts from £1,000 while in-house research costs not much money but time.
A 1,000 complete telephone survey will be costlier than a 100 complete online survey while 50 in-person interviews will be costlier than 10 in-depth interviews conducted over the phone. A 10-question survey targeted at 200 general consumers will be less expensive than a 40-question survey targeted at 800 B2B C-Level decision-makers.

4. How much time does market research take?

Qualitative research takes comparatively less time to complete than quantitative one.
An email survey is completed (~75%) usually within 24 hours of the initial invite and an online survey project can be done in ~2 weeks while focus groups (using 2 groups) and in-depth interviews typically last 4 to 5 weeks owing to the time involved in recruiting participants in addition to the fieldwork.

Conclusion

Nielsen, Ipsos, and Kantar are the three top picks for a majority of research offerings globally. In retail measurement, Nielsen along with Information Resources, Inc. (IRI) are the two major players while consumer panel services and analytics services witness Nielsen, GfK, Ipsos, and Kantar as the major ones.

For audio audience measurement, Nielsen, along with Kantar and GFK, are the global players while in television audience measurement, Nielsen, Kantar, GfK, and Ipsos are the major ones.

The emergence of new technologies, particularly software technologies associated with artificial intelligence and machine learning, has a significant impact on the research market. Further, the very nature of the research conducted has changed owing to the advent of other technologies such as virtual reality.

Companies like Ipsos and Nielsen have already adopted artificial intelligence and machine learning while IQVIA has adopted machine learning.
