A Guide on How CX Can Benefit Your Paid Performance Budget

Have you found that maximising your ROI on paid media campaigns has become more challenging than ever?

With rising customer acquisition costs (CAC), heightened competition, and increasingly sophisticated consumers, even the most well-funded campaigns struggle to cut through the noise. While marketers often pour more money into ad budgets to drive performance, this approach overlooks a powerful multiplier: customer experience (CX).

If you’ve come across any of our previous articles, you’ll know by now that CX isn’t just a buzzword—it’s the foundation for creating lasting connections with customers. Yet, many brands fail to integrate it into their paid media strategy. By enhancing CX, brands can unlock higher conversions, greater retention, and a significant boost in ROI.

In this guide, we’ll explore why CX should be a cornerstone of your marketing strategy, how it amplifies your paid media performance, and actionable steps to create a CX-driven growth plan.

Let’s dive in…

What is Customer Experience, and Why Does it Matter?

Customer experience (CX) is more than just the touchpoints between a brand and its customers—it’s the overarching perception customers develop from every interaction they have with your business. From engaging with your ad to navigating your website and receiving post-purchase support, CX is the cumulative result of your brand’s efforts to meet and exceed customer expectations.

Have you ever experienced it when you’ve clicked on an ad but the website takes ages to load, the web page is confusing to navigate, and it’s completely put you off the potential of even getting to the checkout?

You’re likely to never engage with that brand again!

Similarly, a customer who receives irrelevant follow-up emails is less likely to return. Every experience, whether positive or negative, contributes to the customer’s overall impression of your brand.

Why does this matter?

Because brands that excel at CX don’t just convert more sales —they earn loyalty. Customers are more likely to return, recommend your brand, AND engage further when they feel their needs are understood and met.

The Growing Importance of CX in Digital Marketing

There’s no doubt that digital marketing has transformed the way brands connect with their audiences for the better. But with greater opportunities come greater expectations. Today’s customers demand:

• Personalisation: Ads and experiences that feel tailored to their preferences.
• Seamlessness: Smooth journeys across every touchpoint, online to offline and back again.
• Speed: Quick load times, instant responses, and hassle-free interactions.

Failing to meet these expectations doesn’t just impact conversions—it damages your brand’s reputation and increases churn. In fact, studies show that:

• 88% of customers value CX as much as the product or service itself
• 32% of customers will stop engaging with a brand after one bad experience

These trends underscore the critical role CX plays in modern marketing. It’s no longer enough to run brilliant ads—the post-click experience must deliver on the promise made by your campaigns.

The ROI of Combining CX and Paid Media Investment

The Traditional Approach: Spending Solely on Paid Media

For years, marketers have traditionally leaned heavily on paid media to drive growth.

The logic seems sound: more money = more visibility, clicks, and conversions. However, this approach is increasingly showing its limitations.

Here’s why:

1. Saturation of Paid Channels: Digital ad platforms like Google Ads and Meta are more competitive than ever, leading to skyrocketing costs per click (CPC).
2. Diminishing Returns: As budgets grow, the incremental gains from additional spend shrink. Simply putting more money into ads doesn’t guarantee better results.
3. Disconnected Experiences: If your landing pages, website, and post-purchase communications don’t align with the promises made in your ads, potential customers drop out of the funnel.

In short, a “media-only” strategy often leads to wasted spend and underwhelming results.

The CX Advantage: Spend Smarter, Not More

What if you could achieve more with the same budget—or even less?

Well that’s the promise of integrating CX into your paid media strategy. By reallocating just a portion of your ad spend toward improving CX, you can dramatically increase ROI.

Here’s how it works:

• Better Conversions: CX improvements—like faster load times, intuitive navigation, and personalised landing pages—reduce friction and encourage customers to complete their purchase.
• Higher Retention: Happy customers are loyal customers. Investing in post-purchase CX keeps them coming back, reducing your reliance on costly acquisition campaigns.
• Enhanced Brand Perception: A seamless, enjoyable experience differentiates your brand from competitors, driving organic growth through word-of-mouth and referrals.

In fact, we have seen first-hand how reallocating just a fraction of budget from media into CX can radically improve results. For example, spending £1 on media and £0.50 on CX has delivered a 3x ROI improvement compared to the marginal lift you’d see by simply adding another £1.50 into media spend alone.

Why is this impressive?

Because it shows the compounding effect of CX: every pound spent doesn’t just buy more impressions. It improves the entire funnel, increasing conversion rates, average order value, and retention. In other words, CX investment doesn’t just add incremental value; it multiplies the impact of your existing media budget.

Real-World Applications

For Hillarys we created bespoke landing pages for paid social channels and they are now their most valuable pages on the site (out of every single page). Revenue per user increased from £6.12 to £8.17.

A fashion retailer that invested in personalised product recommendations on its website saw a 40% increase in conversion rates, compared to just 10% from an increased media budget.

Key CX Strategies to Maximise Paid Media Performance

Personalisation Through AI and Data Insights

Personalisation is no longer optional—it’s the expectation. Thanks to advancements in artificial intelligence (AI) and data analytics, brands can deliver hyper-relevant experiences at scale.

Here’s how:

• Dynamic Content: AI tools can tailor landing pages, ads, and email content based on a user’s browsing history, purchase behaviour, and demographic data.
• Predictive Insights: Machine learning algorithms can anticipate what a customer is most likely to want or need, enabling you to serve them with the right message at the right time.

Unique Insight: Personalisation isn’t just about data—it’s about empathy. Brands that use AI to create emotionally resonant experiences outperform those that rely solely on technical targeting.

Enhancing On-Site UX

Your website is the make-or-break point of your paid media strategy. If visitors encounter a slow, confusing, or inconsistent experience, you’ll lose them before they convert.

Key areas to optimise:

1. Load Times: Google estimates that a one-second delay in mobile page load time can reduce conversions by 20%!
2. Navigation: Ensure your site is easy to explore, with clear paths to purchase
3. Mobile Optimisation: With the majority of traffic coming from mobile devices, responsive design is non-negotiable

Pro Tip: Use heatmaps and session recordings to identify friction points in your user journey.

‍

Post-Purchase CX and Customer Retention

The customer journey doesn’t end at the checkout—it’s just beginning!

Post-purchase CX is critical for turning one-time buyers into loyal advocates.

Strategies to consider:

• Retargeting with Purpose: Use post-purchase data to show ads for complementary products or services.
• Loyalty Programmes: Reward repeat customers with points, discounts, or exclusive access.
• Feedback Loops: Ask for reviews or suggestions to show customers you value their input.

Investing in post-purchase CX doesn’t just increase lifetime value—it also reduces churn and acquisition costs.

Measuring the Impact of CX on Paid Media Performance

Key Metrics to Track

Obviously, the more you can track, the more successful you will be in putting together solid strategies. In the words of the famous Peter Drucker, “you can’t manage what you don’t measure”. But you may be thinking ‘where do I start’?

To understand the impact of CX on your paid media campaigns, start by monitoring these metrics:

• Conversion Rate: A higher rate indicates that your CX improvements are reducing friction and driving results.
• Cost Per Acquisition (CPA): Lower CPA shows that your paid media spend is more efficient.
• Customer Lifetime Value (CLV): A rise in CLV reflects stronger retention and loyalty.

Tools for Measuring Success:

Platforms like the below can provide actionable insights into how CX and paid media interact:

• Google Analytics - used for measuring website traffic and user behaviour on the site to help businesses assess the performance and engagement across each page of their site
• Hotjar - used for measuring how users interact with a website through installing heat maps onto each page of the site so you can see in-depth where people are clicking and how audiences are interacting throughout the whole customer journey
• Customer experience platforms like Qualtrics - helps organisations measure and analyse data for a variety of purposes such as collecting customer data, analysing customer satisfaction, and gathering primary research to influence your wider CX strategy

Of course, the foundation starts with core analytics tools like Google Analytics for traffic, Hotjar for behavioural insights, and CX platforms like Qualtrics for capturing customer sentiment. But in this current media landscape, particularly for brands investing heavily in media, it’s the more advanced measurement approaches that really move the needle.

AI-driven attribution modelling, predictive CLV forecasting, and integrated media-CX dashboards can connect the dots between spend and customer lifetime value in real time. These methods go beyond clicks and conversions, showing you exactly how CX improvements amplify your paid media ROI across the full journey.
