> Quick answer: Google has no dedicated review ad format. You embed customer testimonials into Responsive Search Ads, Responsive Display Ads, or Performance Max campaigns. Prepare your testimonial copy and visuals first. Then upload them to Google Ads and let Google's machine learning optimize the combinations.
What is a Review Google Ad?
There is no "review ad" button in Google Ads. A review Google ad is a creative strategy. You take real customer quotes and build them into standard Google ad formats.
Google Ads doesn't have a dedicated format. It's a creative strategy.
Testimonials live inside the ad types Google already offers. Write a headline like *"5 stars. Best purchase I've made this year."* and drop it into a Responsive Search Ad. That's a review ad.
Testimonials work in RSAs, RDAs, and Performance Max
Per Google's Ads Help Center, Responsive Search Ads support up to 3 headlines and 2 description assets. Responsive Display Ads let you pair images with text across placements. Performance Max reaches Search, Shopping, YouTube, Display, Discovery, Gmail, and Maps from a single campaign. Any of these formats can carry your testimonial.
Why testimonials drive trust and conversions
Real customer words lower skepticism. Shoppers trust peer reviews more than brand claims. A short, specific quote in an ad headline does more than a generic CTA.

Step 1: Choose Your Ad Format
Pick the format that fits your testimonial type before you write a single word.
Responsive Search Ads for text-heavy testimonials
RSAs are pure text. They're ideal when a quote stands alone. Write the testimonial as a headline. Keep it tight and trim it to the sharpest, most specific phrase.
Responsive Display Ads for visual testimonials with images
RDAs combine images, logos, and text. Per Google's documentation on Responsive Display Ads, Google's machine learning optimizes asset combinations across different screen sizes and placements automatically. Pair a customer photo or product image with a review quote.
Performance Max for multi-channel reach
Performance Max gives one campaign access to every Google surface. It needs more assets: headlines, descriptions, images, logos, and optionally video. If you have multiple strong testimonials, Performance Max can run them all at once.

Step 2: Gather and Generate Testimonial Content
Strong testimonials are specific. Vague praise does not convert.
Collect real customer reviews and quotes
Pull quotes from Google Reviews, product pages, or customer emails. Look for quotes that name a specific result or feeling. "Doubled my leads in 30 days" beats "Great product" every time.
Use AI to generate variations of testimonials
Real quotes need polish and variety. AI can rephrase a long review into a punchy headline. It can also generate multiple tonal variations of the same testimonial for split-testing.
Ensure compliance. Testimonials claiming results need disclaimers.
Per Google's Advertising Policies on unreliable claims, any testimonial that implies specific results must include a visible disclaimer. The disclaimer must state there is no guarantee of specific results and that results can vary. This rule applies to text ads and display ads alike.
---
Step 3: Create Ad Copy and Visuals
Good testimonial ads have two parts. The quote. And the context that makes it believable.
Write headlines and descriptions featuring testimonials
For RSAs, use the testimonial as the first headline. Follow it with your brand name or product in the second. Use the description to reinforce who the customer is, what they achieved, and why it matters.
Design or generate images showcasing customer success
For RDAs and Performance Max, you need images. Per Google's Ads Help Center, you can upload up to 20 image assets per campaign. Each one goes through a quality and policy review before it serves. Use high-resolution visuals: a customer photo, a product shot, or a branded quote card all work.
Store all assets in Creative Library for reuse
Keep every headline, description, and image organized in one place. You will want to reuse strong testimonials across future campaigns and formats without rebuilding from scratch.
---
Step 4: Build Your Campaign in Google Ads
Now you upload what you have built.
Upload headlines, descriptions, and images to your chosen format
For RSAs, enter your testimonial quotes as headlines in the campaign builder. For RDAs and Performance Max, upload your images and enter text assets in the asset fields.
Use Google's machine learning to optimize combinations
Google tests headline and description combinations automatically. Per Google's documentation, providing multiple varied assets gives the algorithm more to work with. More combinations mean better matching to each user's intent and placement.
Set targeting, budget, and bidding strategy
Choose your audience signals, daily budget, and bid strategy. For Performance Max, add audience signals to steer the algorithm early. For RSAs, use keyword targeting within a Search campaign.
---
Step 5: Monitor and Optimize
Launching is step one. Improving is the ongoing job.
Track which testimonials and visuals perform best
Inside Google Ads, check asset performance ratings. Google labels each asset "Learning," "Low," "Good," or "Best." Keep the "Best" testimonials running. Pause the "Low" ones.
A/B test different review quotes and formats
Swap in new testimonials regularly. Test a result-focused quote against an emotion-focused one. Test a longer description versus a short punchy version.
Refresh underperforming assets
Ad fatigue hits every campaign. An asset rated "Low" after enough impressions needs replacement. Go back to your testimonial bank and rotate in something fresh.
