Responsive Search Ads (RSA) Best Practices

05/12/2025

What are Responsive Search Ads?

You give the ingredients; Google cooks the meal.

In the past, you wrote one specific ad (Headline 1 + Headline 2). Today, Google uses Responsive Search Ads (RSAs).

How it works: You provide a list of many options:

Up to 15 Headlines.

Up to 4 Descriptions.

Google's AI mixes and matches them automatically. It learns which combination works best for each specific user.

User A might see a combination focusing on "Price."

User B might see a combination focusing on "Quality."

The "More is Better" Rule

Don't be lazy with your inputs

The power of an RSA comes from variety. If you only give Google 3 headlines, the AI has nothing to test.

Best Practices for Assets:

Fill all 15 slots: Try to write as many unique headlines as possible.

Be Distinct: Don't just say the same thing 5 ways ("Buy Shoes," "Get Shoes," "Purchase Shoes").

Headline A: Product Name (Red Running Shoes)

Headline B: Benefit (Run Faster Today)

Headline C: Price (From $50)

Headline D: Call to Action (Shop Now)

Vary Lengths: Write some short headlines and some long ones so Google can fit them on different screen sizes.

The Art of "Pinning"

How to control the chaos.

Sometimes, you need to be 100% sure a specific text shows up. (For example, a legal disclaimer or your Brand Name).

You can use the Pin feature.

Pin to Position 1: This headline will always show first.

Pin to Position 2: This headline will always show second.

⚠️ The Warning: Do not pin everything! If you pin Headline 1, Headline 2, and Headline 3, you have turned off the AI. You are forcing Google to show only one version. Rule of thumb: Only pin what is legally required. Let the AI handle the rest.

Ad Strength vs. Real Performance

Don't obsess over the "Excellent" score.

Google gives your ad a score: Poor, Average, Good, Excellent. This score measures variety, not sales.

It is possible to have an "Excellent" ad that makes no sales.

It is possible to have an "Average" ad that makes millions.

Use the Ad Strength score as a guide to ensure you have enough keywords, but focus on your Conversion Rate to judge success.

ClickSambo Tip: Because RSAs automatically test thousands of combinations, they often find new traffic sources. Some of these sources might be low-quality or bot-heavy. Always monitor your ClickSambo reports when launching a new RSA to ensure the "new traffic" is actually human.
