How to Test Responsive Search Ads (RSAs) Like a Pro

Responsive Search Ads (RSAs) are a new and powerful way to create text ads on Google Ads. Unlike traditional text ads, RSAs allow you to create multiple headlines and descriptions, which are then dynamically combined by Google to create unique ad variations. This provides advertisers with more flexibility and options to find the best-performing ad variations. However, testing RSAs can be challenging, and requires a strategic approach. In this article, we’ll cover everything you need to know to test RSAs like a pro.

Understanding Responsive Search Ads

Before we dive into testing, it’s essential to understand the basics of RSAs. RSAs are Google Ads text ads that can display up to 15 different headlines and 4 different descriptions. When creating RSAs, you can add multiple headlines and descriptions, and Google will automatically test and show the best-performing ad combinations based on the search query, device, and other factors. This means that your ad could show up in a variety of different formats, depending on the user’s search query and device.

Setting Up Your RSA Campaign

To start testing RSAs, you’ll need to set up a new campaign in Google Ads. Here are the steps to follow:

  1. Log in to your Google Ads account and click on the “+” button to create a new campaign.
  2. Choose your campaign goal and campaign type.
  3. Select your target audience, location, language, and other settings.
  4. Under “Ad Group Type,” select “Standard” or “Dynamic Search Ads.”
  5. Create a new ad group and choose “Responsive search ad” as the ad type.
  6. Add your headlines and descriptions, making sure to follow Google’s guidelines for character limits and best practices.

Testing Your RSAs

Once you’ve set up your RSA campaign, it’s time to start testing. Here are some tips and best practices to help you get started:

  1. Start with a few variations: To avoid overwhelming yourself and your campaign, start with a few variations of headlines and descriptions. This will allow you to quickly identify which combinations work best for your campaign.
  2. Use Google’s ad strength tool: Google’s ad strength tool can help you optimize your RSAs and improve your ad performance. The tool analyzes your ad copy and provides recommendations for improvements, such as adding more headlines or descriptions.
  3. Test different ad groups: You can create multiple ad groups with different variations of headlines and descriptions. This will allow you to test different messaging and ad formats to see which ones perform best.
  4. Monitor your ad performance: Keep an eye on your ad performance metrics, such as click-through rate (CTR), conversion rate, and cost per click (CPC). Use this data to identify which ad variations are performing best and adjust your campaign accordingly.
  5. Test over time: Don’t rush to conclusions based on a few days or weeks of data. Give your campaign time to gather data and test different ad variations to find the best-performing combinations.


Testing RSAs can be challenging, but it’s essential to ensure that you’re getting the most out of your Google Ads campaigns. By following the tips and best practices outlined in this article, you’ll be well on your way to testing RSAs like a pro and achieving better ad performance. Remember to start with a few variations, use Google’s ad strength tool, test different ad groups, monitor your ad performance, and test over time. Good luck!
