What Is Customer Research?

Customer research is the systematic process of gathering insights about your customers’ needs, behaviours, and motivations. It involves directly engaging with your audience to understand their daily challenges, preferences, and expectations.

For growth marketers, customer research is essential. It helps you make informed decisions, optimise your marketing strategies, and deliver products and services that genuinely resonate with your target audience.

Why Customer Research Matters for Growth Marketers

Great marketing doesn’t come from guesswork—it comes from directly asking your customers about their challenges and needs. Customer research provides clarity on what your audience truly values, enabling you to create targeted messaging, improve your product offering, and ultimately drive growth.

Even if you don’t yet have customers, speaking with prospects can provide invaluable insights. Direct customer insight is often free or low-cost, so there’s no excuse not to prioritise it.

At Growth Method, we actively encourage our customers to seek insights from their audience. In our Getting to Know Your Business questionnaire, we ask:

Do you actively seek insights from prospects and customers? For example - user testing, polls, surveys, analytics, heatmaps, session recordings, sales call recordings, customer interviews? If so, is this done regularly as a repeatable process or more of a one-off?

Qualitative vs Quantitative Customer Research

Customer research typically falls into two categories: qualitative and quantitative. Understanding the differences between these two approaches helps you choose the right method for your goals.

For a deeper look at the numbers side, read our guide to quantitative marketing research, and its qualitative counterpart.

Qualitative ResearchQuantitative Research
Explores customer motivations, opinions, and behavioursMeasures customer behaviours and attitudes numerically
In-depth insights from smaller sample sizesBroad insights from larger sample sizes
Methods include interviews, focus groups, and open-ended surveysMethods include analytics, closed-ended surveys, and A/B testing

Common Customer Research Methods

Here are some of the most effective methods growth marketers use to gather customer insights:

Always-On Customer Research

Customer research shouldn’t be a one-off project—it should be an ongoing, systematic process. Adopting a regular approach helps you continuously gather insights and create feedback loops that inform your marketing and product strategies.

One effective way to implement always-on customer research is to set up a regular “customer coffee hour”. Here’s how:

  • Block out one hour per week for customer calls (two 30-minute conversations).

  • Create a discussion guide to structure each conversation.

  • Rotate team members (founders, product, engineering, marketing, sales, customer success) to ensure insights are shared across the organisation.

  • Use your CRM to automate scheduling calls with customers or prospects each week.

  • Record and transcribe calls using AI tools like Granola.ai, Otter.ai, or Tl;Dv.

  • After each call, spend five minutes documenting key insights in a shared document.

Over time, this shared document becomes an invaluable resource for your content, product, and sales teams. It can also be a great way to collect customer reviews and testimonials for your website.

How Growth Method Supports Your Customer Research

Growth Method is the practical way to use AI in marketing. Our agents suggest campaigns from your own data, then help you plan, launch and analyse them, with no AI vendor lock-in, security taken care of and humans in the loop. It takes each campaign from idea to analysis, so customer insights turn into campaigns rather than sitting in a document.

With Growth Method, you can:

  • Turn customer insights into campaign ideas, each written as a hypothesis and ranked against your growth goals, then categorised by channel and scored for effort automatically.

  • Connect analytics platforms like Google Analytics, Amplitude and Mixpanel to centralise your quantitative data.

  • Get an AI-written summary of each campaign at every stage, and use the AI analysis at the Analysing stage to check whether each result can be trusted, with a verdict on every campaign.

  • Share individual, team and leaderboard reports, plus a weekly email, to communicate customer insights and campaign results to stakeholders.

We are on-track to deliver a 43% increase in inbound leads this year. There is no doubt the adoption of Growth Method is the primary driver behind these results.
