Performance Marketing Runs the Full Commerce Journey in 2026

For years, performance marketing has been measured at the top of the funnel. Acquire the customer, hit the ROAS target, repeat. But as the cost to acquire customers has risen significantly across paid channels, and customer paths have become more complex, eCommerce brands are rethinking what performance really means and where it begins and ends.

We spoke with the team at Genie Goals, a performance marketing agency working with eCommerce brands across retail, fashion, and beyond, about the tactics that are working, the metrics that matter, and how smart brands are building for sustainable growth in 2026.

The rising cost of acquisition is forcing a better strategy

Acquisition costs have been a defining challenge across Google and Meta for several years. The brands that have navigated it best have invested differently, rather than simply cutting budget or putting more money into the same channels.

The shift starts with a willingness to hold flexible ROAS targets and follow consumer patterns rather than chasing a fixed number. A high ROAS usually means you are speaking largely to customers who already know your brand. Real growth comes from reaching new audiences, and that calls for comfort with lower returns earlier in the journey.

For example Q4, tends to favour the brands that have already done the hard work. In practice, this means investing in awareness in September and accepting a lower ROAS during that period, so that by November your audience already knows who you are, what you sell, and is far more receptive to converting. When peak season arrives, you may even spend less than you competitors because the hard work of building your audience is already complete.

The brands that skip that step often end up competing at full cost during the most expensive periods of the year, speaking to a shallow pool of already familiar customers and questioning why growth has stalled.

From cost per acquisition to revenue per customer

There is a growing conversation in eCommerce about shifting focus from cost per acquisition to revenue per customer. In retail, acquisition remains the North Star for many brands, but the conversation around average order value and lifetime spend is becoming impossible to ignore.

When consumers are more careful about where and how they spend, encouraging a larger basket value becomes a meaningful growth lever. Getting more value from a customer at the point of purchase and ensuring they return is what makes the initial cost of acquiring them worthwhile.

These are two separate measures of how well a business is performing. The first asks how effective your marketing is at finding new customers. The second asks how good you are at extracting value from them over time. Both matter and need to be measured. Often, the strongest businesses have both perform well.

Subscription brands have understood this for some time, focusing heavily on ensuring customers reach a minimum contract length or spend threshold before it becomes profitable. But the same logic applies to retail: the value of a customer compounds with every subsequent purchase, and performance marketing has a role to play throughout that journey, not just at the start of it.

Tactics that are delivering right now

The paid tactics working for growing eCommerce brands right now share three things in common, they:

• Build awareness at scale.
• Use creative that actually stands out.
• Expand the number of places where a brand can be found.

Upper funnel investment is back on the agenda, and rightly so. Whether through Demand Gen, Meta, or content partnerships via the affiliate channel, brands that only speak to existing customers cannot grow. Consumers need to know you exist before they can consider buying from you.

Creative strategy has expanded significantly. It is no longer just about brand imagery. Creator ads on Meta are delivering click-through rates well above standard ad benchmarks, and the best brands are treating influencers as part of their creative toolkit, not a separate brand activity. Creators offer both organic advocacy and paid performance, and the two reinforce each other.

Diversification is also a genuine growth lever, but only when it is done with purpose. Expanding onto new social channels or working with more affiliate partners should be driven by the desire to be present where your audience already is, not simply to tick boxes. Early tests and small investment cases are the right way to approach new channels, not all-in bets.

Conversion and the on-site experience

Driving traffic to a site is only valuable if that traffic converts. A growing number of brands are making platform shifts, with Shopify being the most common destination, in part because of the ecosystem of tools it supports for conversion optimisation.

Increasingly, brands are bringing more of the commercial conversation on-site rather than sending customers off to third-party deal destinations. That means building curated offer and deal pages, optimising those pages for search, and using on-site technology to present compelling offers before a customer exits.

Brand-to-brand partnerships shown at checkout are a particularly strong example of this: relevant, margin-safe, and available at exactly the moment a customer is deciding whether to complete their purchase.

Tracking and attribution underpin all of this. Without robust conversion tracking, confidence in investment decisions erodes, and scaling becomes guesswork. Server-to-server tracking has become a major industry focus, particularly in the affiliate channel, and the brands getting it right are the ones able to scale with confidence rather than hope.

A case study worth paying attention to

When Genie Goals took over the affiliate programme for The Diamond Store, the programme was dominated by voucher sites, with approximately 80% of partner activity. For a brand that rarely runs discount codes and was not looking to compete on price, the mix had become completely misaligned with commercial goals.

The team had two clear objectives: build a partner programme that added value continuously, not just at peak, and ensure it was ready well ahead of Q4. That meant a full reset. Removing partners, rebuilding from scratch, and prioritising partners that gave customers a genuine reason to purchase again and again. Closed user groups and loyalty platforms became a central part of the strategy, enabling The Diamond Store to build targeted offers using single-use codes.

Cross-channel learning played a significant role. Content partnerships with The Independent and Glamour were activated over Q4, focused on editorial formats including listicles and gift guides. These were assigned awareness KPIs. The conversion impact was a genuine surprise: the traffic driven by editorial content converted at a rate far beyond what had been anticipated.

The programme forecast 200% year-on-year growth in November. It delivered 475%. Beyond the numbers, the outcome shifted how affiliates were viewed internally: from a legacy channel with limited potential to a channel worth sustained investment.

What a performance marketing audit actually looks at

When auditing an eCommerce brand, the most valuable starting point is often the one that gets skipped: the overall business picture. Looking at year-on-year revenue growth relative to spend and channel mix, before diving into individual channel performance, tells a story that channel-by-channel analysis often obscures.

If a brand is spending more and growing less, the issue is rarely a single channel. It usually points to a broken funnel, misaligned KPIs, or an overreliance on one channel to do work that requires several. Understanding the full picture first prevents teams from fixing the wrong thing.

The second thing worth examining is whether the KPIs being used actually align with the goals being stated. A brand that says it needs new customers but insists on a high ROI target for all activity has an inherent conflict built into its strategy. Awareness activity, by definition, operates at a lower immediate return. If that is not reflected in how success is measured, the brand will consistently underinvest in the very activity it needs most.

Rethinking what performance means

Performance marketing has always been good at acquisition. The opportunity now is to extend that thinking across the full Commerce Journey: from awareness, through conversion, into post-purchase, and through to repeat purchase and long-term loyalty.

The channels and mechanics exist to support each of those stages. The partnership channel, in particular, is one of the most cost-effective ways to drive loyalty, from brand-to-brand partnerships that give customers an additional reason to return, to loyalty platforms that reward continued engagement. 

Moving away from the idea that acquisition is the only metric that matters, and retention sits in a separate silo, frees teams to ask the questions that actually drive growth: what is the goal, how do customers actually shop, and is this activity an effective way of reaching them?

When you frame it that way, acquisition and lifetime value stop being competing priorities. They become two parts of the same answer.
