Google Responsive Search Ads: Here’s Everything You Need to Know

Google Responsive Search Ads

Responsive Search Ads (RSAs) are text ads that allow PPC marketers to create multiple headlines and descriptions that are tested over time by Google’s machine learning and turned into relevant ads customized for the end-user based on their search query.

They were introduced in 2018 by Google as a way to help advertisers find the winning combination of headlines and descriptions for effective text ads.

How do Responsive Search Ads work?

You basically create a bunch of different text components (a maximum of 15 headlines and 4 descriptions) and Google finds the best combination and serves ads to the end-users that lead to the highest CTR and best conversion rates.

The more headlines and descriptions you provide, the more combinations it can generate.

Responsive Search Ads Examples

Here’s an example of a Responsive Search Ad. On the left, there are 10 headline variations and 3 different descriptions. On the right, you see a couple of possible ad combinations.

Keep in mind that headlines and descriptions may appear in any order.

Initially, there’s a learning period for any new RSA, which means performance may not be what you’re used to right away. But once Google finds the best combination, you can see great results.

At Digi Experts, we carried out a study in May 2022 on RSA performance by covering over 13,000 randomly chosen Digi Experts user accounts and answered questions like:

  • Is RSA usage as common among advertisers as one thinks?
  • How does RSA performance compare to that of ETAs?
  • What effect do pinned headlines/descriptions have on performance?

We’ve presented the results by category so you can quickly find what’s most relevant to your goals.

One of our observations was we found that RSAs drive 4x the impressions of a typical Expanded Text Ad (ETA).

This means that even with a slightly lower conversion rate, this 400% lift in impressions nets a lot of incremental conversions that should make advertisers very happy.

Google sunsetted Expanded Text Ads

In August 2021, Google announced that starting from July 2022, Responsive Search Ads (RSAs) will be the only search ad type in standard search campaigns.

The official announcement, posted by Sylvanus Bent, Product Manager at Google Ads, added, “However, your existing Expanded Text Ads will continue to serve alongside Responsive Search Ads, and you’ll still see reports on their performance going forward. Additionally, you’ll be able to pause and resume your Expanded Text Ads or remove them if needed. You’ll also still be able to create and edit Call Ads and Dynamic Search Ads.”

This is a pretty big shift in how PPC marketers approach text ads. For that reason, we spoke to two of the top PPC experts in the industry, Mark Irvine and Julie Bacchini, in June 2022 in our 58th episode of PPC Town Hall to learn how to make the most out of your RSAs.

What does this mean for PPC Marketers who still use Expanded Text Ads?

Expanded Text Ads are comfortable, reliable, and offer you more control over what messages get shown and when. On the other hand, Responsive Search Ads can improve performance when combined with human optimization and creativity.

But since none of us can force Google to roll back their announcement, the best thing to do is adapt to RSAs.

Here’s a free Google Ads script for you to quickly migrate your ETAs to RSAs.

As with any other updates from Google, what we can do is unlearn, relearn, and adapt. Here are a few things to keep in mind as you get started with the transition from ETAs to RSAs:

1. Decide whether to pin headlines and descriptions.

Pinning headlines or descriptions to specific positions in your Responsive Search Ads is one way to show certain messages that always need to be visible. But be warned – pinning may affect ad strength, visibility, and performance.


Verticals like pharmaceuticals (which require specific information in ads) and legal services (which require approval of each ad variant) might need to pin specific pieces of text, such as disclaimers and warnings in their ads. Google is yet to announce whether these industries with obligations will be assessed differently, or if there will be a workaround.

But should you be really pinning your assets? Here’s a clip from one of our Town Halls where Julie, Mark, and Fred discuss pinning.

As our CEO, Frederick Vallaeys says in this Search Engine Land article, unless you’re working in a field that absolutely requires certain information to be displayed, try not to pin components and instead put in the work to craft great RSAs.

2. Test your ad copy.

Create and test different versions of your ad assets at scale, and review their performance across multiple campaigns.

Yes, this means putting more effort than usual into high-quality ad copy that can work across combinations and permutations. But the payoff is rewarding when you have RSAs (up to 3 per ad group) that Google’s machine learning can test to find the best variants.

Our other recommendations include:

  • Repurposing high-performing content from your Expanded Text Ads
  • Evaluating the success of your ads based on incremental absolute metrics – impressions, clicks, and conversions

Does Ad Strength of Responsive Search Ads Affect Their Performance?

Ad strength is the newest type of score advertisers see in their accounts when running responsive search ads. And Google states this about ad strength: “Ad Strength helps you make the best first impression.”

If you see their choice of words there, it means ad strength is not learning from your actual performance. And while a good first impression matters, long-term results matter even more.

Once you’ve got a good baseline ad, you need not worry about ad strength because while it reflects what has worked well for the masses in the past, it doesn’t care about what works for you. An advertiser whose ad with ‘poor’ ad strength starts to perform very well will still be labeled as ‘poor’.

To sum it up, the ad strength of your RSAs does not change based on their performance.

So if you’re an experienced marketer there’s nothing wrong with creating an ad that you think will perform really well, even if it happens to have a poor ad strength according to Google’s predictions.

What matters much more, in that case, is close monitoring and methodical experimentation to make sure that the actual performance reflects what you believe the ad can achieve.

Let the machines learn!

Responsive Search Ads are right in the sweet spot of machine learning within PPC. But for the machines to learn, you need to give them a little time and space to explore.

Resist the urge to pin ad components when you don’t have to. And allow time for a test. It’s essential to feed the machine the appropriate ad components.

The machines are not coming up with new ad text on their own. They use the elements YOU provide, which means the machines can only be as successful as you’ve set them up to be.

It sort of goes without saying, but deploying the proven winners across your ads gives you a better chance at success.

If you’ve already created some Responsive Search Ads in your account but they’re underperforming, here’s how you can fix them:
