The Hidden Costs of a Manual Deployment

Every hour spent replicating targeting rules and building personalization setups is an hour of lost conversions. Manual steps not only waste time, they open the door to costly mistakes:

• Misconfiguration risks: One small targeting error can undo your test’s gains.
• Lost momentum: Successful experiments risk being abandoned or delayed.
• Revenue leakage: Every delay slows the compounding effect of your wins.

Your experimentation process should power growth, not bottleneck it.

Instantly Activate Your Winning Variation

This is why we are thrilled to introduce the Auto-deploy feature in VWO Feature Experimentation.

This powerful new capability transforms your optimization workflow by bridging the gap between a successful test and a permanent deployment. Once your experiment reaches statistical significance and a winner is declared, VWO automatically generates and deploys a personalization rule that perfectly replicates the winning variation.

• Accelerate your time-to-impact. Eliminate the need to manually build new rules. As soon as a statistically valid winner is identified, VWO deploys it automatically to your target audience. This means you start realizing the business impact of your discovery instantly, not after you’ve found time to execute the manual setup.
• Error-free execution: The auto-generated personalization rule precisely mirrors the test’s traffic allocation and original targeting. There is no need for risky re-configuration or manual data entry. What you tested is exactly what you deploy.
• Statistically-driven automation: This isn’t just blind automation. The auto-deployment only happens when your experiment reaches statistical significance, hence ensuring every change is backed by conclusive evidence.

How Does It Work?

1. Experiment reaches statistical significance.
2. VWO creates a personalization rule identical to your winning variation’s setup.
3. The winner goes live instantly, closing the gap from test completion to deployment in seconds.

Your A/B test is a clear winner: A new version of your e-commerce experience, combining an adjusted search algorithm with dynamic pricing, significantly lifted conversions. That’s a huge success. But the next critical question is, what truly drove that success? Was it the smarter search results, the new pricing logic, or was it the unique combination of both working together? Answering this question is the key to scaling your learnings across the entire product.

Is just getting a winning variation enough?

Is just getting a winning variation enough?

When a winning variation consists of several changes, understanding the contribution of each ingredient is the next level of optimization. A/B testing confirms the winning recipe, while Multivariate Testing (MVT) helps you understand if it was the pinch of salt or the dash of pepper that truly elevated the dish. However, uncovering the impact of their interaction has historically required a frustrating and inefficient process:

• Tedious manual setup for every possible combination, which is not only time-consuming but also highly prone to configuration errors.
• Simplified experiments that force you to test variables in isolation, potentially missing the most profitable combination of your features.
• A lingering uncertainty about which specific changes are driving performance, preventing you from applying these insights with confidence elsewhere. This friction often discourages teams from running their most ambitious and potentially most impactful tests, leaving valuable insights hidden within their results.

Pinpoint your most impactful changes with precision

Pinpoint your most impactful changes with precision

This is why we’re thrilled to introduce Multivariate Testing (MVT) in VWO Feature Experimentation. MVT is the perfect complement to your A/B testing program. It’s designed specifically for when you need to move from identifying the winning concept to understanding the individual elements that drive its success. With MVT, you simply define your variables and their possible values, and VWO automatically creates, serves, and tracks every possible combination for you. For example, to test two pricing models and a feature flag for a promotional banner:

Variable 1 (Pricing): $10, $20 Variable 2 (Promo Banner Flag): False, True

Combinations Pricing Promo Banner Flag Combination 1 10 False Combination 2 10 True Combination 3 20 False Combination 4 20 True

VWO automatically generates and runs the experiment across all four unique combinations, measuring the impact of each on your goals. MVT uncovers the interaction effects between variables. You might discover that the $20 price point converts best, but only when the Promo Banner Flag is set to True. Conversely, you could find the $10 price performs better on its own. This is the kind of deep, actionable insight that reveals the optimal user experience and unlocks maximum impact. The Outcome?

• Significantly faster analysis with the elimination of manual overhead.
• Deeper, actionable insights that reveal the optimal user experience.
• Reduced configuration errors and enhanced testing outcomes.
• Increased confidence to make data-backed optimization decisions that truly move the needle.

You’ve relentlessly tested multiple ideas; tweaked copy, changed colours, shifted element placements, and what not, just to enhance for your key metric of success. But alas, nothing has worked.

Ever wondered why? Because the path to conversions is never direct. It’s not your key element that converts users; it’s often the journey that leads to it. Users might be dropping off during checkout or abandoning sign-ups, but you don’t know exactly where or why they are losing their will to purchase. Your report shows that your key metric is changing, but it doesn’t show you a dedicated view comparing the entire funnel’s performance in specific test variations and personalized experiences.

Well, we are exactly solving this friction for you.

Now you can track entire user funnels in your experiments and personalization campaigns

This capability lets you track and compare the entire user journey, giving you a nuanced view of user engagement at every step in specific variations of your tests, and even in your personalized experiences. This holistic view empowers you to make smarter, more impactful decisions to boost your overall funnel performance.

Comparison view of funnel performance in your test variations

How does this Funnel tracking add value to your optimization?

• Keep track of the entire user journey: Each stage of your funnel is clearly depicted, showing the number of unique conversions at each step. This allows you to visualize the flow and identify bottlenecks.
• Identify specific drop-off points: The visual tapering of the funnel immediately highlights where users are abandoning the process. This critical information guides your efforts to improve specific stages.
• Understand how specific variations/experiences perform: When analyzing a campaign, the funnel chart displays the performance of each variation/experience side-by-side, making it easy to compare and understand which flow is most effective in guiding users to conversion.
• Achieve higher optimization velocity: With immense clarity of your key user funnels, you are able to uncover hidden insights faster, leading to more hypotheses, and as a result, a higher number of experiments and personalization campaigns.

How does this help your brand?

For E-commerce brands:

• Checkout Funnels: Test different trust signals in the multi-step checkout process to see which one leads to higher purchases.

For SaaS brands:

• Request Demo Flow: For SaaS products or apps, you can understand which messaging boosts demo requests and results into higher leads and engagement.

For Media:

• Subscription Flows: Optimize the user sign-up process by testing different form tone, number of fields, or layouts and understand what increases the number of subscriptions purchased.

Simply put, it’s time to bid goodbyes to hunting metric performance individually and mapping it down to your user journeys. Instead, use funnels, and get to the nuanced insights faster, at scale.

Excited and want to know more?

You can use this funnel tracking in the Enterprise plans of VWO Testing – Web, VWO Feature Experimentation, and VWO Personalize.
