Expanded Text Ad Record - Bulk
Defines an expanded text ad that can be downloaded and uploaded in a bulk file.
This ad format works seamlessly on mobile, tablet and desktop devices so you can focus more on crafting your longer ad copy and optimizing your ad text to better engage your customers before they click your ad.
Note
- Upgrade your expanded text ads to responsive search ads by February 1, 2023. After this date, you will no longer be able to create new or edit existing expanded text ads. For more information, see About responsive search ads.
- Existing expanded text ads will continue to serve, and you'll be able to view reports on their performance.
- You'll still be able to pause, enable, or remove your expanded text ads. Otherwise, attempts to add or update expanded text ads will result in a
CampaignServiceAdTypeInvalid
error. - Learn more about this change.
Note
Expanded text ads can only be created in Search campaigns where the Ad Group Type is set to "SearchStandard". If the Ad Group Type is set to "SearchDynamic", then the ad group does not support expanded text ads.
You can download all Expanded Text Ad records in the account by including the DownloadEntity value of ExpandedTextAds in the DownloadCampaignsByAccountIds or DownloadCampaignsByCampaignIds service request. Additionally the download request must include the EntityData scope. For more details about the Bulk service including best practices, see Bulk Download and Upload.

Ad Format Preference
The Ad Format Preference field is used to indicate whether or not you prefer the ad copy to be shown to users as a search or audience ad. Search ads tend to be written as a call to action, whereas audience ads should be written in more of an informational style. While you have the option to use expanded text ads as audience ads, designating an ad as Audience ads preferred format allows you to optimize its messaging for native delivery.
Important
You must define at least one expanded text ad per ad group that does not prefer audience ads, otherwise the ad copy of all expanded text ads will be eligible for both search and audience ads.
Possible values are Audience Ad and All. If set to All, the ad will be eligible for both search and audience ad formats. If set to Audience Ad, the ad will only be eligible for the audience ad format.
Add: Optional. If you do not set this field when creating an expanded text ad, by default the ad format preference will be set to All.
Update: Optional. If no value is set for the update, this setting is not changed. If you set this field to the delete_value string, the prior setting is removed. If you set this field to delete_value, the ad format preference will effectively be set to the default value i.e. All.
Delete: Read-only
Ad Group
The name of the ad group that contains the ad.
Add: Read-only and Required
Update: Read-only and Required
Delete: Read-only and Required
Campaign

Delete: Read-only
Client Id
Used to associate records in the bulk upload file with records in the results file. The value of this field is not used or stored by the server; it is simply copied from the uploaded record to the corresponding result record. It may be any valid string to up 100 in length.
Add: Optional
Update: Optional
Delete: Read-only
Custom Parameter
Your custom collection of key and value parameters for URL tracking.
In a bulk file, the list of custom parameters are formatted as follows.
Format each custom parameter pair as Key=Value, for example {_promoCode}=PROMO1.
Microsoft Advertising will accept the first 8 custom parameter key and value pairs that you include, and if you include more than 8 custom parameters an error will be returned. Each key and value pair are delimited by a semicolon and space ("; "), for example {_promoCode}=PROMO1; {_season}=summer.
A Key cannot contain a semicolon. If a Value contains a semicolon it must be escaped as '\;'. Additionally if the Value contains a backslash it must also be escaped as '\'.
The Key cannot exceed 16 UTF-8 bytes, and the Value cannot exceed 250 UTF-8 bytes. The Key is required and the Value is optional. The maximum size of the Key does not include the braces and underscore i.e., '{', '_', and '}'.
Note
With the Bulk service the Key must be formatted with surrounding braces and a leading underscore, for example if the Key is promoCode, it must be formatted as {_promoCode}. With the Campaign Management service you cannot specify the surrounding braces and underscore.
Add: Optional
Update: Optional. If no value is set for the update, this setting is not changed. To remove all custom parameters, set this field to delete_value. The delete_value keyword removes the previous setting. To remove a subset of custom parameters, specify the custom parameters that you want to keep and omit any that you do not want to keep. The new set of custom parameters will replace any previous custom parameter set.
Delete: Read-only
Domain

The domain portion of the URL in combination with the path 1 and path 2 strings cannot exceed 67 characters.
The following validation rules apply to Final URLs and Final Mobile URLs.
The length of the URL is limited to 2,048 characters. The HTTP or HTTPS protocol string does count towards the 2,048 character limit.
You may specify up to 10 items for both Final URLs and Final Mobile URLs; however, only the first item in each list is used for delivery. The service allows up to 10 for potential forward compatibility.
Each URL is delimited by a semicolon and space ("; ").
Usage of '{' and '}' is only allowed to delineate tags, for example "{lpurl}".
Each URL must be a well-formed URL starting with either http:// or https://.
If you specify Final Mobile URLs, you must also specify Final Url.

Final Url Suffix
The final URL suffix can include tracking parameters that will be appended to the end of your landing page URL. We recommend placing tracking parameters that your landing page requires in a final URL suffix so that your customers are always sent to your landing page. For more details and validation rules see Final URL Suffix in the technical guides.

Path 1
The first part of the optional path that will be appended to the domain portion of your display URL. The domain portion of your display URL e.g. https://www.contoso.com will be generated from the domain of your Final URL (Final Url field). Then if you have specified a value for Path 1 it will be appended to the display URL. If you have also specified a value for Path 2, then it will also be appended to the display URL after Path 1. For example if your Final Url contains https://www.contoso.com, Path 1 is set to subdirectory1, and Path 2 is set to subdirectory2, then the URL displayed will be https://www.contoso.com/subdirectory1/subdirectory2.
The path can contain IF and countdown functions. Regardless of the total length of all unsubstituted countdown parameters, the final displayed countdown will always use 8 characters out of the total characters available. For more details see Countdown Customizers.
The path can contain dynamic parameters such as {MatchType}. For a list of supported parameters, see the Microsoft Advertising help article What tracking or URL parameters can I use?.
The maximum input length is 1,000 characters if you include dynamic text strings. No more than 15 final (not dynamic text) characters can be input. The ad will fail to display or the default text will be used if the length of the final URL domain and the paths combined exceed 67 characters.
For languages with double-width characters e.g. Traditional Chinese the maximum input length is 1,000 characters if you include dynamic text strings. No more than 7 final (not dynamic text) characters can be input. The ad will fail to display or the default text will be used if the length of the final URL domain and the paths combined exceed 33 characters. The double-width characters are determined by the characters you use instead of the character set of the campaign or ad group language settings. Double-width characters include Korean, Japanese and Chinese languages characters as well as Emojis.
The path cannot contain the forward slash (/) or newline (\n) characters.
If the path includes a space, it will be replaced with an underscore (_) when the ad is shown.
Add: Optional
Update: Optional. If no value is set for the update, this setting is not changed. If you set this field to the delete_value string, the prior setting is removed.

Then if you have specified a value for Path 1 it will be appended to the display URL. If you have also specified a value for Path 2, then it will also be appended to the display URL after Path 1. For example if your Final Url contains https://www.contoso.com, Path 1 is set to subdirectory1, and Path 2 is set to subdirectory2, then the URL displayed will be https://www.contoso.com/subdirectory1/subdirectory2.
You can only specify Path 2 if Path 1 is also set.

Tracking Template
The tracking template to use as a default for the URL specified with FinalUrls.
The following validation rules apply to tracking templates. For more details about supported templates and parameters, see the Microsoft Advertising help article What tracking or URL parameters can I use?
Tracking templates defined for lower level entities e.g. ads override those set for higher level entities e.g. campaign. For more information, see Entity Limits.
The length of the tracking template is limited to 2,048 characters. The HTTP or HTTPS protocol string does count towards the 2,048 character limit.
The tracking template must be a well-formed URL beginning with one of the following: http://, https://, {lpurl}, or {unescapedlpurl}.
Microsoft Advertising does not validate whether custom parameters exist. If you use custom parameters in your tracking template and they do not exist, then the landing page URL will include the key and value placeholders of your custom parameters without substitution. For example, if your tracking template is
https://tracker.example.com/?season={_season}&promocode={_promocode}&u={lpurl}
, and neither {_season} or {_promocode} are defined at the campaign, ad group, criterion, keyword, or ad level, then the landing page URL will be the same.
