Travel RDA Asset Mix Under Brand and Legal Constraints
An online travel agency runs a Responsive Display Ad campaign for a winter city-break promotion across five European markets. The RDA has 5 short headlines (all under 30 characters), 2 long headlines, 4 descriptions, 3 landscape images (1200x628), 2 square images (1200x1200), 1 logo (1200x1200), and no portrait image. Google Ads shows ad strength 'Good'. CTR fell from 0.72% to 0.38% over four weeks while impressions rose 60% after the team added a broad 'travel' affinity audience. Two landscape images contain a 20% text overlay reading '30% OFF'; one square image is a product screenshot with small text. Brand guidelines require the logo to appear in every creative, and legal requires the discount claim to be visible. The team wants to pause every low-CTR asset and keep only the single best-performing image to 'stabilize results'.
1. Evaluate the asset mix against responsive display ad best practices. What would you add, remove, or rework, and why?

The mix is thin on formats and diversity. There is no portrait image, which is the dominant format in many mobile feeds, so the ad loses eligible placements; add at least one 4:5 or 3:4 portrait image. Three landscape and two square images give the system little to rotate, and all five short headlines plus two long headlines skew short - add longer headlines and more descriptions that can carry the offer without relying on baked-in text.
Rework the text-overlay images: text baked into an image is cropped, scaled, and not localized across five markets, and it competes with the headline. Put '30% off' in a headline and a description, where it is readable and translatable, and keep the images as clean destination or lifestyle shots. Replace the screenshot with small text - it will be illegible on small placements. Brand logo belongs in the logo asset rather than burned into every image; that satisfies brand guidelines without ruining the photo. The discount claim stays visible through ad copy.
2. How should the team interpret the CTR drop after adding the affinity audience, and what does that imply for creative decisions?
Read the worked answer
Impressions rose 60%, so campaign-level CTR is now a blend of a previously narrow, higher-intent audience and a much broader, lower-intent one. A drop from 0.72% to 0.38% can be pure mix dilution rather than creative failure. Before changing assets, split CTR and conversion rate by audience segment, placement, and device. If the affinity segment has lower CTR but similar or better conversion rate, it is not a creative problem. If CTR and conversion rate both fall, the creative may be mismatched to the new context - for example, destination imagery performing in feed placements but not in apps.
Use asset-level reporting to see which headlines and images are actually serving with which combinations. Do not pause assets on CTR alone: an image with modest CTR may combine with a strong headline to produce conversions, and removing it shrinks the combination pool. Judge assets on conversion rate and CPA by segment, and keep at least the recommended minimum count for each asset type.
3. Ad strength is 'Good'. What does that tell you and what does it not tell you? How would you run a creative test within the brand and legal constraints?
Read the worked answer
Ad strength is a diagnostic of asset quantity, diversity, and coverage - whether there are enough headlines, descriptions, and images across formats and lengths. 'Good' means the inputs are adequate, not that the ad will outperform a competitor or that the current creative is optimal; 'Excellent' is achievable with more asset variety, but neither rating predicts CPA. It also does not tell you which assets drive results or whether the offer is compelling.
To test: create a second RDA with a deliberately different asset set (portrait image added, offer in headline, screenshot removed) and run it as a campaign experiment or a separate ad group with even traffic split, holding targeting and bids constant. Keep the logo in the logo asset in both variants to satisfy brand, and keep the discount visible in copy in both to satisfy legal. Measure conversion rate and CPA, not CTR alone, and run for at least two weeks or until each variant has enough conversions. Campaign experiments are cleaner than pausing assets, because pausing reduces the combinations the system can learn from.
