How to Collect Complete Website Data Without Relying on Cookies

Collecting data from your website sounds simple enough, right? Install a web analytics tool like Google Analytics or Adobe Analytics, set up a few tags based on the insights you want to track—and voila! You’re now watching your visitors’ every click, scroll, and session in real time.

From there, it's a straight shot to optimising every touchpoint of their digital experience and hyper-personalising their journey until they convert. Revenue goes up, marketing gets a pat on the back, and the boardroom is all smiles.

Except… in reality, it rarely works out that smoothly.

There’s one tiny, overlooked element that turns this dream into a data nightmare.

Sweet Little Thing Called—A Cookie Banner!

In theory, in the EU and EEA region, the cookie banner is just a GDPR checkbox—a compliance requirement to inform users and give them control over their personal data. In US market, cookie consent banners are just polite pop-ups that allow users to manage their own data.

In practice? It’s the biggest silent killer of your behavioural data.

What Happens When Users Opt Out of Cookies?

When a user accepts cookies, great—you’re allowed to collect and analyse every interaction. Marketers get their insights. Data teams can help them model user journeys. Management sees rising KPIs.

But what happens when the user declines? Or worse—ignores the banner?

They disappear from your analytics radar.

A 2023 Pew Research Center survey revealed that 67% of US adults disable cookies or website tracking to protect their privacy. That means if 10 people land on your site, you may only be collecting behavioural data from 3 of them.

Imagine optimizing your customer journey based on a third of the picture. It’s like trying to solve a puzzle with most of the pieces missing.

That’s exactly the problem a major eCommerce client of ours was facing. And here’s how they solved it. 

Shift to Cookieless Analytics with Adobe AppMeasurement

Behavioural Data Loss Due to Cookie Consent

This wasn’t just a minor hiccup for a client—rather a growing concern. Like many global brands, they relied on Adobe Analytics to drive digital decisions, optimize campaigns, and fine-tune user experiences. However, their tracking setup depended heavily on cookie consent. And every time a user declined—or ignored—the cookie banner, their behaviour vanished from the dataset.

One by one, valuable insights were slipping through the cracks.

Marketing strategies became harder to validate. Conversion paths turned into question marks. Key business decisions had to be made with only part of the picture.

Something had to change.

What Was Happening Behind the Cookie Banner

Here’s how it worked before:

• When a user landed on the site, they were shown a cookie banner.

• If they accepted cookies, Adobe Analytics (via AppMeasurement and ECID service) tracked them normally, including setting visitor cookies and plugin-based cookies (like GPV).

• If they declined, nothing happened—no data collected, no insight gained.

This left major gaps in their user journey analysis, campaign effectiveness tracking, and overall marketing performance.

Cookieless Doesn’t Mean Clueless

Instead of accepting data loss as the new normal, an eCommerce client made a bold move.

They decided to rebuild their Adobe Analytics implementation—this time, with cookieless tracking in mind.

The mission was clear:

·       Keep the user’s right to privacy intact.

·       Stop losing behavioural data when cookies are declined.

·       Make the new setup as close as possible to the old one (so analysts wouldn’t have to relearn everything).

How? By using custom, consent-friendly identifiers that work without cookies or local storage. If a visitor accepts cookies, everything runs as usual. But if they decline, Adobe Analytics still fires—silently, compliantly, and anonymously—thanks to this smart ID-based setup.

No cookies. No problem.

100% Behavioral Data, 0% Privacy Risk

Today, clients can finally see the whole picture.

Their updated implementation now captures 100% of website visitors’ behaviour, whether cookies are accepted or not. That means their marketing and data teams no longer operate in the dark. Every decision—from campaign adjustments to UX improvements—is based on complete and compliant data.

Even better, the switch was seamless. Most plugins and tracking points remained intact, with only minimal tweaks needed.

This is what future-proof web analytics looks like.

What Your Team Can Learn from Our Client?

1. Incomplete data leads to incomplete decisions.

If you're only tracking users who accept cookies, you're missing a significant number of your audience.

2. Cookieless tracking is possible—and powerful.

With platforms like Adobe Analytics and the right implementation strategy, you can capture behavioural data without sacrificing privacy or compliance.

3. The cookieless future is already here.

Users care about privacy. Regulators demand compliance. Your analytics strategy needs to adapt—or get left behind.
