Conversion Rate Optimization (CRO), on which many people depend for improving website results, is a data-driven process designed to increase the percentage of visitors who complete a desired action: making purchases, signing up for newsletters, and filling out contact forms. But despite the undeniable might of CRO, it’s only effective to a certain extent. After every effort has been exerted, there is a point where the returns start to diminish. That would be considered as the “diminishing returns” of CRO.
How do you determine when further CRO efforts may not be worth the resource expenditure? This post will look at signs of diminishing returns, why this happens, and ways to adapt your strategy for sustainable growth.
What’s Conversion Rate Optimization, and when should it be undertaken?
Before we launch a full-scale attack on diminishing returns, let’s stop a moment and define CRO. Fundamentally, CRO means finding obstacles in your sales or sign-up funnel and removing them from your site. Those obstacles can be:
- Speeding up pages to improve the user experience
- More clear and persuasive calls-to-action
- Headlines, images, and layouts all tested A/B on Friday to see what was most successful
- Simplifying checkouts with the minimum of hiccups possible so carts aren’t abandoned
When it’s done properly, CRO can turn even minor shifts in results. For example, a single change for your headline could lead to a 10% or 20% increase in sign-ups. However, this potential doesn’t last long.
Understanding Diminishing Returns in CRO
To illustrate the concept of diminishing returns in CRO, this means it is helpful to take the economic viewpoint as an example. Think of a farmer who is planting crops in a patch of land. The addition of fertilizer might dramatically increase yields at its outset to be sure, but very soon after that, more fertilizer will not bring substantial growth. The same principles apply to CRO.
In the early stages, you’ll find big wins by addressing the obvious inefficiencies on your website. As your site becomes more streamlined in areas such as URL structure and navigation, each small tweak will yield smaller, less-obvious improvements. Eventually, you might feel that you’re putting more effort into your CRO work than it’s worth–and only getting a minuscule return for all those hours spent on site optimization. Learn more about CRO.
Signs You’re Getting Diminishing Returns With CRO
Your Improvements Are No Longer Significant
In early stages of CRO, you might see conversion rates jump from 3% to 5% or even 10% after making changes. But if your improvements are now less than 0.5% from an A/B test, then it’s time to restrategize what you’re doing altogether.
In addition, small wins are still valuable. But if the overall impact is consistently low, it may mean that there are no more big issues to resolve and that we’re heading into diminishing returns.
Costs Are Rising Faster Than Returns
CRO requires resources, whether it’s on tools such as heatmaps and A/B testing software, or bringing in experts who can guide you through the process. If your team is dumping more money, time, or energy into producing change than that change is worth for them, then it ceases to be cost-effective.
Consider, for instance, this scenario: if you spend $5,000 on a CRO initiative but your monthly added income is only $300, that’s diminishing returns.
Your Conversion Rate Is Near Industry Benchmarks
Each industry has an ideal conversion rate. For online shops 2% to 3% is the average. If you are already outpacing this range, then it is hard to go any higher without making big changes.
Over-optimization That Hurts Customer Experience
Sometimes in the pursuit of higher numbers, a business might lose sight of the bigger picture. By aiming for greater values of certain figures such as CTR and conversion rate, companies may end up with materially cluttered pages full of popups that pitch products they are marketing.
If your website feels less natural and more like a constant series of experiments in CRO, you run the risk of losing customers and causing yourself long-term trouble.
Tests Are Frequently Yielding “No Significant Difference.”
If you are A/B testing things and steadily always arriving at “no significant difference” as your results, this could mean that you’ve hit a wall in the way of optimization opportunities.
For example, this is especially common when you’ve already run tests on and optimized the most crucial elements of your funnel to avoid Pickers having any possible way of getting past them.
Why Do CRO Suffer from Diminishing Returns?
There are a variety of reasons for this:
- Limited Low-Hanging Fruit: Easy issues are rectified at the beginning, with less powerful gains later on.
- Saturation Point: There’s only so much optimization you can perform before it runs up against a hard limit and your website or product reaches its natural ceiling.
- Testing Fatigue: The more times you make changes, the fewer results they generate. Changes made are getting smaller and smaller in academic impact. Over time, repeated testing may yield fewer insights as changes become more incremental and thus less transformative.
- External Constraints: Targets such as the size of your target audience, market conditions, or constraints imposed by a given product may limit how much can be achieved solely based on site adjustments.
What to Do When You Hit a Plateau in Your CRO Efforts
Just because CRO approaches the point of no longer offering winners does not mean you should give up on it altogether. Instead, this is an opportunity to step back and reassess your strategy, putting forward more holistic plans for future growth.
Focus on Other Areas for Improvement
However, if CRO isn’t providing the kind of returns you had hoped for, consider other approaches to reach improved overall results. These could include:
- Driving More Traffic: Stepper up your efforts in SEO, PPC, or social media campaigns to diversify and push into the top of your customer funnel.
- Improving Product Value: Make what you’re offering seem to have more value through things like improved branding, an update of features, or better help with customer support.
- Expanding Audience: Look for segments or markets you’ve never touched before, and try selling them something different from what you normally sell.
Shift to Long-Term Optimizations
Some areas for improvement might require more than a simple A/B test. For instance:
- Redesign your website with a more modern, intuitive user experience.
- Create personalized user journeys using advanced analytics and segmentation.
- Set conversion metrics outside of just sales, such as an increase in engagement or return visitors.
Use More Advanced Tools and Analytics
By wielding AI and machine learning tools in this way, you can gain deeper insights and automate optimization processes that may have been too complicated or time-consuming to look into back then.
Reframe Your Targets
If getting a higher conversion rate is no longer an option, try finding other KPIs with just as much significance. These could include customer lifetime value (CLV), repeat purchase rate, or average order value (AOV).
It’s Not just about Getting the most Out of Everything
Conversion Rate Optimization is a great tool that can completely change the way you do business. But like any tool, using it too much will eventually make it ineffective. Recognizing signs of diminishing returns can save you time and resources in order to pursue projects with greater, long-term impact.
In addition to continuing to improve CRO, you can supplement other growth strategies, such as getting more traffic, making new products, and expanding your audience. This will create a more sustainable and well-rounded approach to increasing the scale of your business.
If you don’t know how to grow your CRO strategy and begin looking for new growth channels, it may be time to ask some experts up ahead who can help guide you in this next phase of optimization.
