We live in a time when digital marketers have to do far more than just design a set of beautiful ads. The real challenge isn’t just creativity: it’s automation, rapid experimentation, and responding to real data—all at scale. For creative teams and agencies, automating your creative testing workflow for display ads isn’t just about saving time, it’s about unlocking a level of reach, brand consistency, and campaign insight that simply isn’t possible when you’re bogged down by manual work.
Why Automate Creative Testing for Display Ads?
- Speed: The more ideas and variants you can deploy fast, the faster you discover what works. Manual resizing and tweaking? That’s old news.
- Consistency: Automation lets you maintain iron-clad brand consistency across all touchpoints, even when generating dozens of ad sizes.
- Efficiency: By automating the repetitive parts of ad production and testing, you free up your creative and strategy teams to do what matters: ideate, analyze, and optimize.
- Scalability: The bigger your campaigns, the more you need quick production of assets—resized, branded, and ready to go—without sacrificing quality or wasting hundreds of hours.
Building an Automated Creative Testing Workflow
-
Start with Data and Clear Hypotheses
Look at your past campaigns. What creative elements underperformed? Are there gaps in size options by network, or inconsistent messaging? Be intentional by forming hypotheses to test (e.g., Will a bold versus subtle CTA color convert better on 300x250px mobile displays?).
-
Centralize Your Brand Assets
Nothing kills testing efficiency like lost logos or outdated fonts. Use dedicated brand kit management (like in SizeIM) to centralize your brand resources. This ensures every variant reflects your latest guidelines, automatically.
-
Design Once—Resize Instantly Across All Needed Formats
Design your master creative and automatically generate every required size for platforms like Google, Facebook, and direct publisher placements. With SizeIM, select the template, upload your assets, and pick from a list of over 15 popular ad dimensions, including:
- 300x250px (Inline Rectangle)
- 728x90px (Leaderboard)
- 160x600px (Wide Skyscraper)
- 320x50px (Mobile Leaderboard)
- and many more…
You’ll have all your creative variants ready in minutes—not days or weeks.
-
Experiment Systematically: Test, Measure, Iterate
Move beyond simple A/B tests. Use these methods:
- A/B Testing: Swap a single creative element at a time for rapid insights.
- Multivariate Testing: Combine variables for deeper learning—try multiple headlines, images, and CTAs together across sizes.
- Rotating Batches: Swap out low performers every week and double-down on winners.
Pair creative automation with analytics from your ad network or marketing dashboards to track impressions, clicks, and conversions per variant.
-
Optimize Based on Real Insights
By systematically archiving and annotating both high and low performers, you build a historical knowledge base. This dramatically speeds up iteration on future campaigns since you know exactly what creative choices drive results.
Display Ad Creative Testing: Best Practices for Automation
- Always test with intention: Change one variable at a time for A/B testing. For multivariate, map out your combinations in advance.
- Start with at least 5-8 variants per audience segment: More variants lead to faster learning. Don’t settle for just two or three.
- Set your success metrics early: Know your benchmarks for click-through rate, conversion rate, CPA, or engagement before you launch.
- Review performance weekly: A seven to ten day feedback loop keeps your campaigns fresh and ensures you’re not wasting spend on underperformers.
- Document top performers and learnings: Save your winning creatives and note what worked. Your future campaigns will thank you.
