Things are changing in the world of marketing. Privacy is just now becoming an expected right on the internet, which is good! But it’s not so good for marketers who rely on third-party data. Let’s go over how to transition into using first-party data for your marketing needs.
What Is First-Party Data (And Why It Matters Now)
First-party data is any information you collect directly from your own customers and website visitors. That includes purchase history, email sign-ups, contact forms, app activity, and how people interact with your site. You completely own this data. Nobody sold it to you and nobody can take it away.
For years, businesses leaned on third-party data instead. That’s information bought from outside sources, usually collected by tracking people across websites they didn’t own. It’s how you’d end up looking at hiking boots on one site and seeing hiking boot ads everywhere else for a week.
You know that annoying pop-up banners that ask about your privacy preferences? Those are (usually) third-party data-tracking methods. And they’re phasing out. Third-party cookies are becoming less powerful as Google, Chrome, and other web tools are phasing them out.
So the data small businesses used to rent is disappearing, which means the data you actually collect yourself just became a lot more valuable. Information is power and you need to make sure that you’re staying on top of it.
Why It’s More Valuable Than Ever for Small Businesses
Here’s the shift: advertising platforms used to do a lot of the targeting work for you. You’d set a few parameters, and the platform’s third-party data would fill in the rest, finding people who looked like your ideal customer based on browsing behavior across the web.
As that data dries up, platforms are leaning harder on what businesses upload themselves. If you have a list of past customers, a CRM full of leads, or site visitors who filled out a form, that information can now do the heavy lifting your ad campaigns used to get for free from cookies.
This matters most for small businesses because you don’t have the massive ad budgets to make up for weaker targeting. A local HVAC company or boutique gym can’t out-spend a national brand. But a well-built customer list can make a small ad budget perform like a much bigger one, because you’re showing ads to people who already have a reason to care.
However, this also means that you do need to invest a bit more time and effort into collecting that first-party data…
How to Collect First-Party Data
Collecting first-party data isn’t as complicated as it sounds. It’ll just require some initial set-up. But trust me, future you will thank you. Most businesses already have more of it than they realize sitting in places they haven’t connected yet.
Start with your customer list. If you have email addresses from past sales, invoices, or appointment bookings, that’s first-party data ready to use. Google Ads and Meta both let you upload customer lists to build targeted or lookalike audiences.
Your CRM is another goldmine. Every phone call logged, every quote requested, every lead that didn’t convert yet, all of that tells you something about who your customers are and what stage they’re at.
Site behavior counts too. If you have analytics or a pixel installed, you’re already collecting data on who visits your site, what pages they look at, and where they drop off. If you don’t have any of this installed, then don’t worry. ChatGPT or Gemini can walk you through it. Or, if you work with a marketing agency or freelancer, then they should be able to get it done for you.
But once that’s set up, that’s first-party data building itself in the background.
A simple way to start:
- Export your customer or client list from your CRM or invoicing software
- Make sure your website has a tracking pixel installed for the platforms you advertise on
- Add a newsletter sign-up or lead magnet if you don’t already have one collecting emails
- Set up basic site tracking so you know which pages get the most traffic and where people leave
None of this requires a developer or a big tech overhaul. Most of it can be done in an afternoon.
Turning First-Party Data Into Better Targeting and Lower Ad Costs
Once you have that data, the real value shows up in your ad campaigns. Uploading a customer list to Google Ads or Meta lets you build a custom audience of people who already know your business, which is a much warmer group than cold traffic.
From there, both platforms can build a lookalike audience, meaning they’ll find new people who share similar characteristics to your existing customers. That’s often a stronger targeting signal than anything based on generic interests or demographics.
Retargeting gets sharper too. If you know exactly who visited your pricing page but didn’t book, you can put an ad in front of that specific group instead of guessing at a broad audience.
The payoff over time is lower ad costs. Platforms tend to reward advertisers whose ads perform well with real audiences, and first-party data helps your ads reach people more likely to actually convert. Fewer wasted impressions means your budget stretches further.
