First-Party Data explained

How small businesses can start using it today?

If you’ve noticed your ads aren’t working as well, your targeting feels fuzzier, or your “insights” are less insightful than they used to be you’re not imagining it.

Platforms like Google, Meta and Apple are actively devaluing third-party data. Cookies are disappearing. Privacy rules are tightening. And businesses that relied heavily on rented audiences and external data are losing visibility.

The upside? This shift actually favours small and mid-sized businesses if they learn how to use first-party data properly.

What is first-party data (in plain English)?

First-party data is information you collect directly from your audience people who interact with your brand, not data you buy or borrow.

Examples include:

• Email subscribers

• Customer purchase history

• Website behaviour (pages viewed, downloads, time on site)

• Survey responses

• CRM data

• Event registrations

• Enquiries and lead forms

Because this data comes straight from the source, it’s:

• More accurate

• Privacy-compliant

• Owned by you (not a platform)

• Far more valuable for long-term growth
  

Why third-party data is losing value

Third-party data is information collected by someone else and sold or shared with advertisers - think cookies, interest targeting and audience profiles.

It’s being phased out because:

• Privacy regulations are stricter (GDPR, CCPA, cookie consent laws)

• Consumers want more control over their data

• Browsers are blocking tracking by default

• Platforms are protecting their own ecosystems

In short, you can’t build a sustainable growth strategy on data you don’t own.

Why first-party data is a growth advantage for small businesses

Large brands may have scale, but small businesses have direct relationships and that’s gold.

First-party data allows you to:

• Understand what customers actually care about

• Personalise messaging (without creepy tracking)

• Improve retention and repeat purchases

• Make smarter decisions based on real behaviour

• Reduce reliance on paid ads

This is where profitability improves not by chasing more leads, but by getting more value from the customers you already have.

How small businesses can start using first-party data today

You don’t need complex tech or a data team. Start with what’s realistic.

1. Build (or clean up) your email list

Email is still one of the strongest first-party data channels.

Focus on:

• Clear opt-ins (lead magnets, downloads, events)

• Segmentation (customers vs prospects, interests, lifecycle stage)

• Tracking engagement (opens, clicks, conversions)

Even basic segmentation beats blasting the same message to everyone.

2. Use simple surveys and feedback loops

You don’t need long questionnaires.

Try:

• Post-purchase surveys

• “What made you choose us?” forms

• One-question email polls

• NPS (Net Promoter Score)

This qualitative data adds context to your numbers and helps guide strategy.

3. Track behaviour on your website

Behavioural data shows intent, not just interest.

Start with:

• Most visited pages

• Top converting content

• Drop-off points in forms

• Download or enquiry triggers

Tools like GA4, CRM integrations or basic heatmaps are enough to spot patterns.

4. Use a CRM (even a simple one)

A CRM doesn’t have to be complicated.

At minimum, track:

• Who your customers are

• What they’ve purchased

• When they last engaged

• Where they are in the lifecycle

This turns random marketing activity into intentional, revenue-linked action.

5. Actually use the data (this is the part many skip)

Data is useless if it doesn’t change decisions.

Use it to:

• Refine offers

• Improve onboarding

• Trigger follow-ups

• Personalise content

• Identify retention opportunities

First-party data should inform strategy, not sit in a dashboard untouched.

The bottom line

As third-party data disappears, first-party data becomes your most valuable asset.

Small businesses that win will be the ones who:

• Know their customers best

• Build direct relationships

• Focus on retention, not just acquisition

• Make smarter decisions with less waste

This isn’t about more data.
It’s about better insight, better marketing and better margins.
