Creative Testing for Ecommerce Ads: 3 Tools to Increase Output, Iterate Faster, and Improve ROAS

Today in the competitive ecommerce environment, creative is the core lever that can determine your businesses bottom line through efficiency. It determines if the ad stops someone mid-scroll or gets ignored and burns budget. With rising costs across platforms and audiences becoming more selective, brands that don’t continually aim to improve their creative risk losing strong performance. Testing creative isn’t optional; it’s a growth engine that reveals what resonates, what flops, and what drives real engagement and conversions.

Testing systematically means running small variations of ideas (different hooks, visuals, formats, angles), giving ad engines what they need to find winners and using true performance insights to decide what to scale and what to ditch. Without iteration, you’re essentially flying blind, guessing what works rather than letting data guide your creative decisions.

Below are three of our favourite tools to help you increase your creative output and optimize faster:

1. Blend AI’s Creative Analysis Tab - Know Exactly What to Create
   
   Blend’s Creative Analysis feature gives you actionable insights from your existing ads and audience behaviour so you can understand what creative is actually performing. Rather than guessing whether lifestyle shots outperform product close-ups or if testimonials beat demo videos, Blend breaks down signal trends, performance drivers, and patterns telling you exactly what to test next and where to double down. This transforms creative planning from intuition-based to data-driven and is backed by your data plus over $1B worth of competitor ad data.
   
   Why it matters: You’re generating better ads that align with what your audience already responds to, not just net new creative you have no data to back.
   
   
2. Refunnel - Source Authentic Customer UGC and Turn It into Paid Ads
   
   One of the biggest creative bottlenecks for advertisers is finding fresh, high-trust content. Refunnel helps you tap into authentic user-generated content (UGC) like customer photos, videos from social media and then bring those assets into your ad tests. Real customer content often works well because it feels genuine, relatable, and social-proofed. Refunnel actually streamlines the collection, permissioning, and management of UGC so you can feed it directly into your creative testing pipeline. More importantly it’s a fresh stream of content working hard for you.
   
   
3. Nano Banana - Rapid Creative Generation & Iteration
   
   Nano Banana is Google’s AI image generation model that lets you produce multiple visual variants in minutes from a prompt. It’s an easy way to create dozens of variations (different angles, settings, hooks, compositions) without requiring a design team or costly photoshoot. This enables faster A/B testing of visuals and messaging, helping you iterate based on key performance metrics like Link CTR and CPC instead of pure gut feel.
   
   The faster you can generate quality creative variants, the more tests you can run — and the quicker you uncover winners that improve campaign performance.
   
   

The Bottom Line:

Great ads aren’t made once; they’re discovered through continuous testing and iteration. Combine smart analysis (Blend), rich authentic content, and fast variant generation (Nano Banana) to dramatically increase your creative output and more importantly, your ability to iterate toward higher performance. With the right tools and process, testing creative becomes less like a guessing game and more like a science that powers scalable growth.
