The Ad Text Optimization for Responsive Search Ads is an optimization and insight tool made to help you break down and review your ad performance data by its components. It also allows you to make changes in bulk to different assets. It is available for Google Ads and Microsoft Ads accounts.

Note: Ad Asset level performance data is not available for Microsoft Ads accounts.

With this tool, you can:

By default, the tool will show the last 30 days' performance data of all eligible RSAs in the account. You can click on the filter icon, located in the top right beside the date range option, to modify these settings. This will allow you to filter Ad data by Campaign Type, Bid Strategy Type, Campaign Groups, or Campaign or Ads labels, change date ranges, and filter by networks.

The main header lets you switch performance views between three tabs: Headlines, Descriptions, and Full Ads.

The system aggregates performance data when the same asset is used across multiple RSAs. The Count column shows how many ads use each asset. You can also see the performance rating, pinning status, and impression data.

You can filter ads and assets by Ad Strength, Performance Groups, Low Performing Assets, and status. You can also include or exclude pinned components, set maximum headline/description counts, and use Create Custom Filters for more granular filtering.

The Full Ads tab provides a complete view of your RSAs and is the primary place to create, duplicate, and edit ads. When the same RSA is used across different Ad Groups or Campaigns, performance data is aggregated, though the same ad may have different strengths in different entities.

The Full Ads view allows you to edit multiple assets on the same RSA at once. To edit an ad, click the edit icon next to it. While editing, you can:

If the RSA is present in multiple entities, edits will apply across all of them. Filter by Ad Strength to limit edits to only underperforming instances.

You can duplicate an existing RSA directly from the Full Ads view. This creates a copy of the ad that you can then modify before saving. Duplicating is useful when you want to create a new variation of a well-performing ad without starting from scratch. Changes to the duplicate are saved as a new ad and do not affect the original.

You can create new RSAs directly within Ad Groups from the Full Ads tab. The tool shows an Ad Group Ads column, which displays how many RSAs currently exist in each Ad Group. This makes it easy to identify Ad Groups with fewer ads where adding a new variation could improve coverage and performance.

To add a new ad to an Ad Group:

In the Headlines and Descriptions tabs, you can modify individual assets that may be shared across multiple RSAs. Click the edit icon next to any asset to change its text. Clicking Save labels the asset as “modified,” but no changes are uploaded to Google Ads until you review and finalize.

The tool offers AI-powered suggestions for headlines, descriptions, and full ad drafts. You can apply suggestions directly or make custom edits.

If the asset appears in more than one ad, editing it will update it across all of them. Check the Count column to confirm how many ads will be affected. To limit changes to underperforming ads only, filter by Ad Strength before editing.

You can also pin or unpin assets to specific positions within an RSA from both the asset-level and full ad views.

While editing any RSA or asset, the Spell Check option provides spelling suggestions. Misspelled words are underlined in red — right-click to open the suggestions list and click a suggestion to apply it.

Additional spell check options:

Spell check is currently available in: English (International & UK), French, Danish, Dutch, German, Italian, Norwegian, Spanish, and Swedish.

The Find and Replace feature enables bulk changes across your RSA assets. This is supported for both Google Ads and Microsoft Ads. A common use case is updating outdated text — for example, replacing “AdWords” with “Google Ads” across all ads in one step.

When setting up a replacement, you can:

The "Match whole word" option in the Find and Replace feature's criteria is the following:

If the Option is Checked:

If the character that goes before and after the string contains one of the following, it'll be considered a full word.

[Start of Line, End of Line, space, dot(.), '(', ')', '{', '}', '[', ']', '!', '@', '#', '$', '%', '^', '&', '+', '-', '?', '€','™']

For example, if you have ad text with "Special Plans for New Agencies and End Advertisers Starting from $249/month", the Match Whole Word will match the following:

For the case of the string "Plan" it won't match as a whole word as the ad text is "Plans" (plural) and the string searched for is "Plan". "month" and "249" won't match either as the character "/" is not a matching character.

If the Option is Unchecked:

If the "Match whole word" is unchecked, the strings "New", "Special", "Plan", "month" and "249" will match, as it won't be taking into consideration the previous or posterior characters.

Once you are done, simply press on Preview and Apply Changes to upload the modified ad text to your Google Ads account.

This tool has a unique feature where you can download the changes in a CSV file and share it with the client or other stakeholders for approval.

After you get approval, you can upload the CSV back to Optmyzr and then apply the changes from the tool.

To upload the new CSV file with the updated information, you’ll need to update the "Optmyzr Action" column with the text "edit" next to each row you’ve edited, as shown in the screenshot below. You should also write in "create" in case you have created a new ad. Additionally, this is a case-sensitive command, so the word must be in lowercase for it to work. This way, the system can recognize the changes made.

You’ll see that there is a space before the “Ad Id” and “Adgroup Id” in each respective column. It’s important that this isn’t modified to preserve the format required by the system to recognize the changes.

With the Ad Status, you'll be able to specify whether the ad should be created in an 'Enabled' or 'Paused' state.

You're also able to add any labels you want to your ads by using the Label column.

1. Identify and Replace Low-Performing RSA Assets

Problem: Some assets of your RSAs may stop performing well. Manually reviewing each RSA to identify underperforming assets can take a significant amount of time, especially in accounts with many ads.

Solution: You can filter assets by Low Performing Assets or Performance Groups to quickly identify components that require improvement. Once identified, you can edit the asset directly within the tool or apply AI-powered suggestions to replace weaker ad text.

With this tool, you can efficiently improve your ad performance by quickly identifying and replacing underperforming headlines and descriptions.

2. Generate New Ad Variations Using AI Suggestions
