As marketers, who doesn’t love data? We build our marketing enablement strategies around it. We optimize campaigns because of it. We write content based on it. Good data allows us to do better marketing.
But not all data is equal. As we look ahead to 2026, it’s clear that the most valuable data isn’t coming from third-party sources or rented lists anymore. That era has been winding down for a while, accelerated by cookie deprecation and tightening privacy laws.
The data you need is much closer to home: Your own website.
Your website can be the ultimate first-party data gathering tool, but only if you recognize it as one. Every click, scroll, form fill and chatbot interaction peels back another layer about your audience. Those are strong intent signals that tell you what your audience cares about and where they are in their customer journey.
Let’s walk through how to harness that data strategically and responsibly, using the right tools and mindset to turn website behavior into marketing intelligence.
Marketers have talked about the death of the third-party cookie for years, but it’s more of a reality. Major browsers have phased out third-party cookies, and consumers are increasingly taking matters into their own hands with ad blockers and tighter tracking settings.
Meanwhile, data privacy regulations keep tightening. In 2025 alone, at least eight new state-level privacy laws have taken effect in the U.S. Over 80% of the global population is now covered by comprehensive privacy laws, according to the International Association of Privacy Professionals.
Those shifts lift first-party data to the top of the data food chain.
First-party data is the information your audience shares with you directly: on your website, in your emails, through your forms and chat tools. This includes everything from zero-party data (information customers proactively volunteer) to insights from customer interactions to behavioral signals.
It’s specific to your brand and tied to real behavior. You own it. And because it’s grounded in consent, it gives you a stronger competitive edge with increasingly compliance‑conscious consumers.
A few examples of what your website can collect:
This is data that helps you distinguish between a casual browser and a high-intent buyer, so you can act accordingly.
If you want to capture better data, your website needs to be more than just a digital brochure. Make it an active listening tool, designed for insight as well as engagement and conversion. Here are some ways to do so.
Use tools like GA4, Google Tag Manager or your HubSpot tracking code to log key behaviors and collect data that matters:
Tip: Set up custom events in HubSpot to measure intent. For example, someone who scrolls three-quarters down the page and clicks a secondary CTA may be more qualified than someone who just downloads a single asset. These insights allow you to use first-party data more strategically in your nurture flow.
Forms can do more than simply gate content for inbound marketing. They should also feed segmentation and sales enablement.
Revisit your forms to include:
Also, look at where your forms live. Could you add one to a product or pricing page? That’s valuable contextual data and another opportunity to collect first-party data.
Embed tools that your audience actually wants to use and that will tell you something in return. A classic exchange of information for value.
For example:
All of these generate high-quality, opt-in data points that go beyond clicks and pageviews, feeding your first-party data strategy.
Don’t let your content just sit there. Tie downloads to smart workflows that score leads and assign lifecycle stages.
For example, let’s say a visitor downloads a “How To Scale Manufacturing Ops” guide. Now, you have multiple data points: they’re likely part of an operations team, they have a scaling challenge and they’re far enough along in their research to want a deeper resource. So, they’re tagged as an operations persona and mid-funnel.
That’s the perfect moment to guide them forward with content that matches their intent. Instead of sending a generic nurture email, build a workflow that reacts to this specific behavior. The next email might offer a CTA to a demo video, but you can go even further:
Use tools like Hotjar or Microsoft Clarity to visualize how people move through your site. You won’t use this for every campaign, but it’s a great way to validate which content is working and what’s just in the way.
Gathering first-party data is only half the battle. Putting it to work is where it gets interesting. Here’s how to read between the clicks and act on the insights.
When you track users across your site and tie actions back to individuals or accounts, you obtain better clarity into where they are in their decision process.
A whitepaper download alone might suggest early-stage research. But if that same visitor also returns to view pricing, engages with a chatbot and explores service pages? That’s a mid-funnel lead ready for a more targeted message.
First-party data helps you move beyond broad personas into nuanced buyer signals, so you’re not guessing which campaign to run next. You’re building it around actual customer behavior stored in a customer data platform like your CRM.
First-party data is the MVP of marketing right now, but that doesn’t mean third-party data is out completely. The former gives you accuracy, while the latter can help with reach. Combine the two for smarter targeting at scale.
This hybrid strategy is catching on. Seventy-one percent of publishers recognized first-party data as a key source of positive advertising results in early 2025 (up from 64% in 2024), according to Digiday+ research. But more than half still use third-party data to scale efforts or fill gaps, especially in programmatic or AI-powered campaigns.
Here’s how they work together:
|
First-Party Data |
Third-Party Data |
Combined Approach |
|
|
Source |
Collected directly from your audience |
Purchased or licensed from external sources |
Owned insights + intent and firmographic enrichment |
|
Strengths |
Accurate, timely, privacy-compliant, specific |
Scalable, good for expansion and lookalikes |
Precision targeting at scale |
|
Examples |
Website behavior, form fills, direct messages |
Intent signals, firmographics, browsing on other sites |
Custom audience building, predictive analytics |
|
Limitations |
Limited to your own audience footprint |
Regulatory risk, consent ambiguity, rising costs |
Best of both: Owned depth + broader reach |
So what does this look like in practice?
Used thoughtfully, third-party data doesn’t compete with your first-party data, it complements it. Especially when you're looking to expand into new markets or reach lookalike audiences, the blend offers the best of both worlds: trust and scale.
Programmatic advertising has always promised precision at scale. But that precision depends entirely on the signals you feed into it.
Think about it like this: From your website, you know when someone downloaded a whitepaper or visited your pricing page. That’s signal gold. Combine that with third-party insights about job titles or buying intent, and you go beyond just advertising. You’re orchestrating paid media outreach that feels timely and personal.
That means you can:
And yes, all of this can still happen at scale. Programmatic platforms now make it easier to integrate these richer data sets through secure onboarding tools, so you’re not trading privacy for performance.
Your website is already telling you what your audience cares about. You just need the right strategy to turn those signals into growth. Whether you’re building a stronger first‑party data foundation or running smarter campaigns with the data collected, you don’t have to figure it out alone.
