How to use this RSA preview tool
Use this tool to review likely Responsive Search Ad combinations before launch, approval, or QA.
- Enter the final URL and business name.
- Add your RSA headlines and descriptions.
- Pin only the assets that must stay in a specific position.
- Review multiple preview combinations and check for copy issues.
- Print or save the preview for client review, internal QA, or sign-off.
If you also need tagged landing page URLs for launch, use the UTM Builder to create campaign links and the UTM Validator to check parameter consistency before publishing.
What this preview can and cannot show
This tool is designed for RSA copy review and pre-launch QA, not for predicting the exact live ad layout in every auction.
- It can show: different headline and description combinations, pinned asset positions, display path formatting, and common copy issues before launch.
- It cannot show: exact live rendering across every device, every auction context, or every Google Ads layout variation.
- Use it for: creative review, compliance checks, brand message checks, and client approvals before uploading or editing ads in Google Ads.
For pre-launch QA beyond ad copy review, you can also use the Advertising ROI Calculator to estimate efficiency targets and profitability before campaigns go live.
Responsive Search Ad character limits
Google Ads Responsive Search Ads have fixed character limits for headlines, descriptions, paths, and business name fields. Checking these limits before publishing helps reduce formatting issues and makes ad reviews faster.
| Field | Limit | Notes |
|---|---|---|
| Business name | 25 characters | Required for this preview layout. |
| Path 1 | 15 characters | Optional display path after the domain. |
| Path 2 | 15 characters | Optional second display path. |
| Headline | 30 characters each | Up to 15 headlines, with the first 3 required in this tool. |
| Description | 90 characters each | Up to 4 descriptions, with the first 2 required in this tool. |
- Use shorter headlines when possible to improve readability across combinations.
- Pin only the assets that truly need fixed positions.
- Review multiple combinations before sending ads for approval or launch.
FAQ
How does pinning work in Responsive Search Ads?
Pinning lets you assign a headline or description to a specific position in a Responsive Search Ad. This is useful when a message must appear in a certain place, such as a brand name in Headline 1 or a required disclaimer in Description 1.
Does pinning reduce RSA flexibility?
Yes. Pinning reduces the number of possible headline and description combinations because some assets can only appear in fixed positions. It can be useful for control, but excessive pinning can limit variation.
Will all RSA headlines and descriptions show at the same time?
No. Responsive Search Ads use combinations of available assets, so not every headline or description appears in every impression. A preview tool helps you review likely combinations before launch.
Why do RSA previews change between combinations?
RSA previews change because Responsive Search Ads are built from multiple headlines and descriptions rather than one fixed ad. Different combinations can appear depending on available assets and pinned positions.
Why does my Responsive Search Ad sometimes show only one headline?
Some Responsive Search Ads may appear with fewer visible assets in certain layouts. This can happen because ad rendering depends on available space, device, format, and how Google chooses to assemble eligible assets.
What is the difference between an RSA preview tool and Google Ads Ad Preview and Diagnosis?
An RSA preview tool helps review headline and description combinations before publishing. Google Ads Ad Preview and Diagnosis is used to check live ad visibility and diagnose serving issues.
