What data should small businesses collect from their customers

Understanding your customers is key to growing your business – simple as that.

If you're a small business owner, you're probably wearing about ten hats already, so the idea of “data collection” might feel a bit… daunting. Where do you even start? What’s worth collecting? And how do you use it to hit your sales goals?

Consent mode

Before we get into this you need to know about consent mode.

Consent Mode requires user consent to collect data. Without consent, only limited data is collected, making attribution difficult.

Implementing Consent Mode requires a Consent Management Platform (CMP) to manage user consent; if consent is denied, sessions may not be tracked.

Before even thinking about collecting data, you need to have consent mode properly set up. Use a tool like CookieYes or get in touch with us if you need help.

Why Knowing Your Customers (Through Data) Matters

Think of customer data like a behind-the-scenes tour of your business. It helps you see what’s working, what’s not, and where your best opportunities lie. It also takes the guesswork out of your marketing and gives you the confidence to make decisions based on facts, not gut feelings.

And the best part? It helps you build stronger relationships with the people who matter most – your customers.

Quick note: Always follow GDPR rules when collecting data. Be open about what you're collecting, get consent, and store it safely. Your customers’ trust is everything.
 

1. Demographic Data - Who Are Your Customers?

This is basic stuff like age, gender, location, or job information.

It might seem simple, but this data gives you a clear picture of who your customers are. It also helps you segment your audience and tailor your messaging. For example, if most of your customers are 25–35-year-old professionals, you’ll market very differently than if your core base is retirees.

Use this data to:

✅ Tailor your messaging
Create customer personas 
✅ Target ads more effectively

2. Behavioural Data - What Do They Do?

This is all about how people interact with your brand: on your website, in your shop, or through emails. Are they just browsing? Do they come back often? Do they leave without buying?

This data includes showing your website activity (what pages did your customer visit, how long were they on those pages, did they buy anything, how often do they return)

It’s like watching a customer in a shop – you can tell a lot just by what they look at and what they walk away from.

Use this data to:

Improve your website and user experience
✅ Recommend the right products or services
✅ Spot where people are dropping off

3. Engagement Data - Are They Paying Attention?

Engagement data shows how many people interact with your content, including emails, social media posts, and blog posts.

This includes tracking: email open and click rates, social media likes, comments, shares, and time spent on your content.

If people are engaging with what you’re putting out there, that’s a good sign they’re interested – and possibly ready to buy.

Use this data to:

✅ Create more content that your audience wants
✅ Focus your energy on the best channels
✅ Build trust and loyalty

Jonny's advice

Even a small amount of data can be useful. For example, collecting a first name can help you personalise an email and adding the first name to the subject line can improve open rates. 

The data you collect on website browsing behaviour can also tell you a lot. My advice would be to zoom in on a couple of key metrics, as they can reveal some quick wins. 

Collecting feedback from your customers using Google Forms, can also give you some raw data that will help you understand common pain points and challenges, which is the lifeblood of your marketing.

4. Customer Feedback - What Are They Saying?

Let’s not forget one of the best sources of info: your customers. Whether it’s reviews, surveys, or direct messages, customer feedback is a goldmine of insight.

You’ll learn what’s working, what needs fixing, and what your customers value.

Examples of feedback include: Google or Trustpilot reviews, short surveys after a purchase, and support tickets or live chat conversations.

Use this data to:

✅ Improve your products or services
✅ Strengthen your reputation
✅ Show customers you’re listening
 

Make It Meaningful: Link Your Data to Your Goals

Before you start collecting every bit of data under the sun, take a moment to think about what your actual goals are.
 

Ask yourself:

  • What’s most important for our sales team right now?

  • Which goals, if we hit them, would move the needle?


Common small business goals:

  • Increase monthly sales

  • Convert more leads into customers

  • Speed up the sales process

  • Get repeat customers

  • Reach new audiences or areas


Once you’re clear on your goals, it’s much easier to focus on collecting the data that will help you get there.
 

What Data Helps You Track Progress?

  • Customer acquisition cost (how much it costs to get a new customer)

  • Customer lifetime value (how much a customer is worth over time)

  • Conversion rates (how many leads turn into sales)

  • Churn rate (how many customers stop buying)

  • Campaign performance (how your emails, ads or social posts are doing)

Tracking the right metrics ensures you’re not just doing, you’re improving.

Final Thoughts

Start with the tools you already have – your website, email system, social media, even a good old-fashioned spreadsheet.

And remember, collecting data isn’t just about ticking boxes. It’s about understanding real people. When you know who your customers are, how they behave, and what they think of your brand, you can make better decisions, boost sales, and build lasting relationships.
