For financial services digital leaders, the pressure to prove platform ROI has never been higher. Here's why most Optimizely programmes underperform - and the five things that separate the leaders from the rest
You chose Optimizely for good reasons. Personalised customer experiences, faster experimentation, measurable improvements in engagement and conversion. The promise was clear. The investment was significant.
So why does it feel like the platform isn't quite delivering?
If that question sounds familiar, you're not alone. Gartner's research shows enterprises use just 33% of their martech stack capabilities on average - and that figure has declined for two consecutive years. In financial services, the gap between what organisations have paid for and what they're actually using is often even wider, for reasons that are structural rather than technological.
The good news: the platform isn't the problem. The implementation, operating model, or partner around it almost certainly is. Here's where we see it go wrong - and what the best-performing FS digital programmes do differently.
1. You're using a fraction of what you've paid for
Most Optimizely implementations start with the CMS and stop there. Personalisation rules are bought but never configured. Experimentation modules go untouched because compliance teams aren't set up to review test variants quickly enough. Analytics sit siloed from the content team. Multi-channel delivery is used as a single-channel CMS.
In financial services, this pattern is particularly acute. MoEngage's 2025 research found 58.6% of FS brands take over two weeks just to gather basic customer behaviour data - which means the automated content workflows and personalisation engines already in your Optimizely licence simply can't be used at the pace they were designed for.
And Gartner estimates 85% of DXP programme cost goes to integrations - meaning most budget and bandwidth is consumed getting the platform operational before advanced features are ever touched.
The result? As one industry analysis put it: firms have "burned through seven figures and are using maybe 20% of what they bought."
What to do: Start with a platform usage audit. Map what you've licensed against what's actually activated, and identify the quick-win modules that can be switched on without significant additional investment. Some of Optimizely's most powerful features are accessible within a standard CMS licence - they just need to be properly implemented.
2. You launched, then stopped
The most common failure mode we see isn't a bad implementation - it's a good implementation followed by nothing. Scope, build, go-live, handover. Project closed. Job done.
But Optimizely isn't a project. It's a platform designed for continuous improvement. And without an ongoing optimisation practice, performance plateaus quickly - or quietly declines.
This matters more than ever in financial services right now. The FCA's Consumer Duty now explicitly expects firms to use analytics software for deep insight into customer journeys and to conduct testing and analysis to improve outcomes. Firms that aren't running ongoing experimentation aren't just leaving revenue on the table - they're accumulating regulatory risk.
The contrast with leading programmes is stark. Optimizely's own data shows that organisations using its Opal AI capability run 78.7% more experiments and achieve 9.3% higher win rates. Companies with mature testing programmes are 69% more likely to grow significantly, according to Kameleoon research.
What to do: Treat your platform as a product, not a project. That means monthly roadmaps, always-on performance reviews, and an experimentation pipeline - not a one-off testing sprint. If your current partner only resurfaces at renewal time, that's a signal.
3. Your team is working around the platform, not with it
Here's a pattern we see regularly: a large content team, all interacting with the site, all working in broadly the same way they did before the platform went live. New technology landed all at once at go-live, processes were never properly adapted, and no one has had the headspace to step back and rethink how the team actually operates.
The result is that 65% of content team time goes on routine updates (MarTech.org, 2025) - leaving almost no capacity for the strategic use of the platform: experimentation, personalisation, performance analysis.
In financial services, this is compounded by compliance bottlenecks. COBS 4 rules mean every piece of digital content requires review - and when that review process isn't integrated into the platform workflow, it creates a backlog that effectively freezes advanced features in place.
What to do: Identify internal champions who can bridge technology and team. Build a feedback loop that captures experimentation ideas from the widest group. And be comfortable starting small - even a single well-run A/B test creates momentum and builds the internal case for doing more.
4. You've outgrown your current partner
Organisations evolve. The partner who got you to go-live might not be the right partner to take you to full platform maturity. We see this regularly - as FS clients move into more complex personalisation, tighter CRM and data integrations, and high-volume experimentation, the original delivery partner struggles to keep pace.
The signs are usually the same: reactive rather than proactive engagement, slow turnaround on issues, no strategic challenge or fresh thinking, and no real visibility into where ROI is being left on the table.
For FS organisations specifically, this matters because the stakes of underperformance are rising. Only 28% of FS firms have reached advanced stages of implementing a digital skills strategy (Broadridge, 2024). If your partner isn't bringing the skills and strategic thinking your team lacks, the gap widens every quarter.
What to do: Look for a partner that can offer continuity alongside genuine challenge - one with certified Optimizely expertise, strong relationships with the product teams, and a clear methodology for identifying and unlocking ROI from existing investment.
5. You can't prove the value to the board
This is the one that keeps most digital leaders up at night. And in financial services, it's particularly loaded - because finance functions are often ill-equipped to evaluate digital investment. Gartner found only 17% of finance staff qualify as "digital finance talent." Deloitte's research shows digital ROI typically takes two to four years to materialise fully, with only 13% of organisations seeing returns in the first 12 months - far shorter than the investment cycle most CFOs expect.
The CFO conversation in 2025–26 has shifted from "prove it works" to "prove it scales without eroding margins." And the firms winning that conversation aren't presenting technology capabilities - they're presenting financial outcomes. Cost-to-serve reductions. Customer acquisition cost improvements. Revenue attribution from experimentation. Compliance cost savings from evidenced digital journey testing.
Optimizely's own FS research found organisations achieving 10% revenue growth through experimentation - with 64% planning to increase investment as a result. That's the ROI narrative that resonates: test, measure, attribute, scale.
What to do: Build a measurement framework that connects digital metrics to financial language. Testing outcomes to revenue. Content engagement to funnel performance. Personalisation rules to customer lifetime value. If your current reporting doesn't give the board a clear line of sight from platform activity to business outcomes, that's where to start.
The bottom line
The firms getting the most from Optimizely in financial services aren't doing anything exotic. They're running ongoing experimentation. They're using personalisation at scale. They're measuring outcomes in language the board understands. And they have a partner who challenges their thinking and holds them accountable to a performance roadmap.
The gap between that and where most FS programmes currently sit isn't a technology gap. It's a strategy, skills, and operating model gap.
And it's entirely fixable.
