Cookieless Marketing: How SMEs Build First-Party Data

Third-party cookies have not turned out to be the reliable backbone of digital marketing they once were. After years of planning a full deprecation, Google reversed course in July 2024 and then again in April 2025, ultimately keeping third-party cookies active in Chrome without introducing any new consent prompt.

The direction of travel has not changed, though. Regulatory pressure, browser restrictions on Safari and Firefox, and a broader shift in how users expect their data to be handled all mean that any business still relying on third-party cookie data is building on uncertain ground. For SMEs across Northern Ireland, Ireland, and the UK, cookieless marketing is not a future concern. It’s a present-day strategic priority.

The practical question is what replaces it. The answer lies in the assets your business already owns: your website, your content, your email list, and your customer relationships. This guide sets out how to make marketing cookieless for your business, covering the tools and tactics that make it work, and it explains how to stay on the right side of UK and Irish privacy law while you do it.

Google’s Cookie Reversals: Why the Uncertainty Is the Real Problem

Google’s original plan was to remove third-party cookies from Chrome entirely. After repeated delays, the company announced in July 2024 that it would abandon deprecation in favour of a user-choice model, where a standalone browser prompt would let individuals opt in or out. Then, in April 2025, Google scrapped that prompt too. Chrome continues to support third-party cookies without any new consent screen, with users managing their preferences only through Chrome’s existing Privacy and Security settings.

What This Means for Your Campaigns

Third-party cookies are therefore still technically available in Chrome, but what’s changed is the surrounding environment. Safari and Firefox have blocked third-party cookies by default for years. Consent Management Platforms, ad blockers, and privacy-focused browser extensions all reduce the proportion of users from whom third-party cookie data can actually be collected. Add the growing adoption of VPNs and private browsing modes, and the pool of users generating usable third-party cookie data is already a good deal smaller than headline Chrome market share figures suggest.

The picture across browsers is already patchy. Safari’s Intelligent Tracking Prevention has blocked cross-site cookie tracking by default since 2017, and Firefox blocks third-party cookies by default, too. Together, Safari and Firefox account for a meaningful share of UK browsing traffic, which means a portion of your audience has been unreachable by third-party cookie tracking for years. If your remarketing campaigns, third-party analytics, or behavioural targeting assume full cookie coverage, your data has been incomplete for some time already.

The sensible response is not to wait and see how opt-out rates develop. It’s to build a cookieless marketing strategy that functions regardless of whether any individual user accepts cookies, which means owning your data rather than renting access to it. None of this depends on cookie coverage either; contextual targeting works from the page itself, not a cookie that may or may not exist.

Why UK Brands Face Extra Compliance Pressure

The UK Information Commissioner’s Office has been tightening enforcement on consent banners since the post-Brexit revision of the UK GDPR under the Data Protection Act 2018. Cookie banners that default to accept all, or that use dark patterns to steer users towards consent, are being challenged. The ICO’s guidance is clear that consent must be freely given, specific, and as easy to withdraw as it is to give, so it’s worth reviewing your consent management platform on a regular cycle rather than assuming an old setup still holds up.

Irish businesses face equivalent requirements under the Data Protection Commission, which has been among the more active enforcement bodies in Europe for GDPR violations involving data collected without valid consent. The legal and technical directions point the same way: reduce reliance on third-party cookies now, rather than waiting for a deadline that keeps moving.

Why Your Website Is Your Most Valuable Data Asset

In a cookieless marketing environment, your website is where an owned data strategy begins. Every visitor who lands on your site and takes an action, subscribing to an email list, downloading a guide, filling in a contact form, or creating an account, is giving you first-party data. That data belongs to you, and it does not expire when a cookie policy changes.

Web Design as a Data Capture System

Most SME websites were not designed with data capture in mind. They were built to look good and explain the business, and that’s not enough on its own. A site that generates first-party data needs clear pathways: newsletter sign-up forms at natural pause points in the content, gated resources that exchange genuine value for an email address, preference options that let users tell you what they are interested in, and account-based features the business model can actually support.

The design of these elements matters as much as their presence. A sign-up form buried in the footer converts at a fraction of the rate of one embedded contextually within a relevant article. If your site was built some time ago, it’s worth revisiting the underlying website design with data capture as an explicit goal, because user experience directly affects the quantity and quality of the first-party data you collect. Well-structured content does double duty here: it’s exactly what contextual targeting systems match against.

Consent Management Done Properly

Consent management is not just a legal requirement; it’s a data quality filter too. A user who actively opts in to marketing communication is more engaged and more valuable than one who was tracked without their knowledge. Building a consent management platform that is clear, honest, and genuinely easy to use produces a smaller but far more actionable dataset.

For UK businesses, this means implementing a compliant cookie consent banner that records and stores consent signals, doesn’t pre-tick marketing consent boxes, and provides a real mechanism to withdraw consent. The ICO has published technical guidance on what compliant consent management looks like, and it is worth reviewing alongside your developer or digital agency before your next site update.

Building the Infrastructure: Four Pillars of Cookieless Marketing

Cookieless marketing for SMEs comes down to four interconnected activities. Each one works on its own, but they’re most effective when they connect.

Pillar 1: First-Party Data and CRM Integration

First-party data is information your customers give you directly: names, email addresses, purchase history, browsing behaviour on your own site, and preferences they have shared with you. It’s collected through your own channels and stored in your own systems.

The most common gap for SMEs is not collection; most businesses already gather some first-party data through their websites and email systems. The gap is activation. Data sitting in an unconnected form submission tool or a basic email platform isn’t being used to personalise content, segment communications, or inform ad targeting.

A CRM, even a basic one, changes this. When contact data, email engagement, and website behaviour flow into a single system, you can start to understand which topics interest which segments of your audience, who’s close to making a buying decision, and what content is driving the most valuable leads. That is the intelligence third-party cookie data used to approximate, and first-party data does it more accurately because it comes directly from people already engaged with your business. That same system is also the natural home for consent management records, so segmentation reflects what each contact has agreed to receive.

Pillar 2: Content Marketing as a Value Exchange

Users share their contact details with a business because they expect something useful in return, and content is the most scalable way to create that value exchange.

A well-structured, transparent content marketing programme generates first-party data at every level. Blog articles bring in search traffic. Gated resources, guides, checklists, and templates convert that traffic into named contacts. Email newsletters maintain the relationship and provide ongoing behavioural data. Each layer feeds the next.

This is also where SEO becomes central to a cookieless strategy. Contextual targeting, one of the main alternatives to behavioural cookie tracking in digital advertising, works by matching adverts to the content of the page being viewed rather than to the individual user’s history. The more precisely your website content covers defined topic areas, the better your contextual targeting performs. Good SEO and a good cookieless marketing strategy are built from the same materials.

Pillar 3: Contextual SEO and Contextual Targeting

Behavioural ad targeting used cookies to show the right message to the right person based on what they had previously browsed. Contextual targeting shows the right message based on what the person is reading right now, and for SEO-driven content strategies, that’s an advantage rather than a limitation.

When your site builds genuine topical authority in your sector through in-depth articles, how-to guides, comparison content, and FAQ pages that answer what your customers are actually searching for, you attract visitors at the moment of relevant intent. That’s more precise than a cookie-based system that follows someone around the web for three weeks after they left your site.

A coherent search engine optimisation strategy is the foundation of this approach. Keyword research identifies what your audience is looking for, content creation delivers the answers, and internal linking builds the topical clusters that signal authority to search engines and support contextual targeting downstream. None of that traffic depends on any cookie or tracking technology.

Pillar 4: Video and Owned Social Channels

Video content on owned platforms, your website, your YouTube channel, and an embedded player in an email drives audience engagement without requiring any third-party tracking. A viewer who watches a video on your site is a first-party interaction. A subscriber to your YouTube channel has opted in to your content. Neither depends on cookie consent.

Video suits the cookieless environment particularly well because it is inherently consent-based; people choose to watch. That voluntary engagement produces behavioural signals, watch time, replays, and drop-off points that the platform records as first-party data within your own analytics.

For SMEs, short explainer videos, customer Q&As, and process walkthroughs that address common questions in your sector build the kind of trust that speeds up the data exchange described above. A visitor who’s watched three minutes of content explaining your approach is far more likely to subscribe to your newsletter than one who arrived cold from a display ad. If video marketing is not part of your current mix, this is usually where it earns its place fastest.

Beyond Third-Party Cookies: Alternative Tracking That Works

Reducing reliance on third-party cookies doesn’t mean accepting a gap in your measurement. Several technical approaches keep conversion tracking accurate as part of a cookieless marketing measurement stack, without relying on user-level cookie data. Contextual targeting, covered above, sits alongside these fixes as a non-cookie targeting method, not a replacement for measurement.

Server-Side Tagging and API-Based Conversions

Standard Google Tag Manager and Meta Pixel implementations fire from the user’s browser and get blocked by cookie opt-outs and ad blockers. Server-side tagging moves this process to your web server instead, so conversion data is sent directly from your server to the ad platform’s API, bypassing browser-based blocking entirely.

Meta’s Conversions API and Google’s Enhanced Conversions both work on this basis. For any SME running paid social or search campaigns and worried about data loss from cookie opt-outs, server-side implementation is now worth prioritising. It requires developer involvement and is more complex to set up than standard tag management, but it restores the measurement accuracy that browser-side blocking has eroded. None of this replaces consent management; server-side conversions still need to respect what a visitor agreed to.

Zero-Party Data and Direct Audience Feedback

Zero-party data sits alongside first-party data in a cookieless strategy but is distinct from it. Where first-party data is observed, click behaviour, email opens, and purchase history, zero-party data is declared. The customer tells you directly what they want: their preferences, their intentions, their interests.

Collection mechanisms include preference surveys during sign-up, quiz funnels that recommend products or services based on answers, and explicit interest selection in email preference centres. A Northern Irish solicitor’s firm asking email subscribers whether they need personal or business legal services, for example, creates a segmentation that no cookie could provide. The zero-party data is accurate because it came directly from the person, and it was given voluntarily rather than inferred.

Zero-party data works best when it’s asked for sparingly. A two-question preference survey at sign-up gets answered; a twelve-field profiling form usually does not. Treat every request as a small trade: ask for the minimum, and tell the customer why.

Staying Compliant: ICO and DPC Requirements for UK and Irish Brands

UK and Irish businesses running cookieless marketing strategies still need to handle personal data under the UK GDPR and the EU GDPR, respectively. First-party data is not exempt from data protection law; it’s simply obtained through a more direct and more compliant route than cookie-based tracking, provided your consent management setup captures that permission properly.

The key legal bases for processing first-party marketing data are consent (explicit opt-in) and legitimate interests, for certain types of follow-up communication with existing customers. The ICO’s guidance on direct marketing sets out when each applies and what documentation is required.

Consent must be recorded with a timestamp, the specific purpose communicated at the point of collection, and a genuine mechanism for withdrawal. Pre-ticked boxes, bundled consent for multiple purposes, and consent buried in terms and conditions are all non-compliant.

For Irish businesses, the Data Protection Commission has been particularly active in examining how consent is obtained for email marketing and on-site tracking, so it’s worth reviewing your consent-capture flows against current DPC guidance as a practical risk-reduction step rather than treating it as a one-off exercise. Contextual targeting carries a lighter compliance burden than behavioural tracking, since it works from page content rather than personal data.

ProfileTree founder Ciaran Connolly notes: “The businesses that do best in this environment are the ones that treat privacy as a signal of quality rather than a compliance box to tick. When a customer trusts you enough to share their contact details and preferences, you have better data than any tracking pixel ever gave you.”

How to Make Marketing Cookieless: Five Steps to Take Now

None of this needs to happen at once. The five steps below turn the pillars above into a working cookieless marketing plan, moving roughly in order of dependency, so it is worth tackling them in sequence rather than starting the CRM before the consent banner is sorted.

Step 1: Audit Your Current Data Sources

List every place you currently collect customer data and identify which sources depend on third-party cookies. Common culprits include remarketing pixel audiences, third-party analytics platforms, and ad network lookalike audiences built on cookie data.

Step 2: Review Your Consent Management Platform

Check that your cookie banner meets current ICO and DPC requirements. Confirm it records consent with timestamps, doesn’t default to accept all, and offers genuine withdrawal. If you are on WordPress, most compliant solutions integrate directly with the CMS.

Step 3: Set Up or Connect a CRM

Even a basic CRM that connects your website forms, email platform, and sales pipeline creates the infrastructure to activate first-party data. This doesn’t need to be expensive; several options built for SMEs run on modest monthly subscriptions. ProfileTree’s digital training sessions cover CRM setup and consent management basics for teams who want to handle this in-house.

Step 4: Build a First-Party Data Capture Asset

Create a resource, a practical guide, a checklist, or a short video series that your audience genuinely wants and that justifies sharing an email address to access it. Build the sign-up flow, connect it to your CRM, and measure the conversion rate. A digital strategy built around this kind of asset tends to outperform ad hoc lead magnets, because the asset is chosen to serve a defined audience segment rather than to fill a content calendar. It also earns its keep with contextual targeting, since the asset itself is content that contextual systems can match against.

Step 5: Move Paid Campaign Tracking Server-Side

If you’re running Meta or Google Ads and have not implemented API-based conversion tracking, brief your developer or agency to do so. This is the single highest-impact technical change for restoring measurement accuracy in a cookieless environment.

Building Your Cookieless Marketing Advantage

Cookieless marketing is not a technical inconvenience to work around; it’s a structural improvement for businesses willing to invest in owned channels. Your website, your content, and your direct customer relationships are assets that compound over time, in a way that rented, cookie-based reach never did.

The five steps above are a starting point, not a finish line. As Chrome’s position on third-party cookies keeps shifting, the businesses least affected by the next announcement will be the ones already running on first-party data, zero-party data, contextual targeting, and consent management they control. ProfileTree works with SMEs across Northern Ireland, Ireland, and the UK to build that kind of digital infrastructure.
