Updated Date:
In the past, you wrote one fixed ad (Headline 1 + Headline 2). Today, Google uses responsive search ads (RSAs).
| How it works | You provide a list of options |
| Headlines | Up to 15 |
| Descriptions | Up to 4 |
Google combines these options for each search. User A might see a combination focused on "price," while user B sees one focused on "quality."
The power of an RSA comes from variety. If you only give Google 3 headlines, the AI has nothing to test.
Use as many of the 15 slots as possible: the more distinct headlines you write, the more combinations Google can test.
Be distinct: don't say the same thing five different ways ("Buy Shoes," "Get Shoes," "Purchase Shoes"). Each headline should add something new:
| Headline | Focus | Example |
|---|---|---|
| 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.
Sometimes you need to be sure a specific text appears, such as a legal disclaimer or your brand name.
For this, use the Pin feature.
| Pin to position 1 | This headline will always show first. |
| Pin to position 2 | This headline will always show second. |
⚠️ Warning: Don’t pin everything! If you pin one headline to each of positions 1, 2 and 3, you effectively switch off the AI; Google will always show the same headlines. Rule of thumb: Only pin what is truly required (like a legal disclaimer or brand name) and let the AI handle the rest.
Tip: Pin two or three headlines to the same position to keep control without losing variety.
Google gives your ad a rating: Poor, Average, Good, Excellent. This rating measures variety and relevance, not sales.
You can have an "Excellent" ad that makes no sales, and an "Average" ad that performs very well.
Use Ad Strength as a guide to make sure you have written enough distinct headlines and used your keywords in them. Judge success by your conversion rate and cost per conversion.
ClickSambo tip: Because RSAs automatically test many combinations, your ads may show in more searches and auctions. Some of this new traffic may be low quality or bot-heavy. When you launch a new RSA, keep an eye on your ClickSambo reports to make sure the new traffic comes from real people.
