Ad customizers are a very powerful tool that lets you customize the text content of your responsive search ads using dynamic text placeholders.
Ad customizer
There are two steps for creating an ad customizer for responsive search ads:
Create the customizer attribute.
The customizer attribute is a broad category that describes the kind of change you intend to link to this customizer—for example, "product price" or "discount percent".
Link the customizer attribute with a customer, campaign, ad group, or keyword ad group criterion.
Set the specific values you want to use for the specific resource.
Create a customizer attribute
First, you need to create a new customizer attribute, represented by
CustomizerAttribute
using
CustomizerAttributeService
with
two required fields:
name
- The name of the customizer, which must be unique (case insensitive). Since there is a limit of 40 customizers, you might need to reuse customizers across different resources, so be sure to choose a name that represents a broad category of what kind of customizations this will be used for.
type
- The type of the customizer—text, number, price or percent—defined
by
CustomizerAttributeType
.
When you create a new customizer attribute, you get its resource name back, which is required in the next step.
Link the customizer attribute
You can link the previously created customizer attribute at many levels using the following services:
CustomerCustomizerService
to createCustomerCustomizer
for the customer level.CampaignCustomizerService
to createCampaignCustomizer
for the campaign level.AdGroupCustomizerService
to createAdGroupCustomizer
for the ad group level.AdGroupCriterionCustomizerService
to createAdGroupCriterionCustomizer
for the ad group criterion level. For this type, only keyword criteria are supported.
Regardless of which level you want and which corresponding service you use, the same pieces of information are required:
customizer_attribute
- The resource name of the customizer attribute that you created in the previous step.
value
The value that you want to insert into your ads when you reference this customizer attribute. This field is defined by
CustomizerValue
.You need to specify
type
andstring_value
to createCustomizerValue
. Thetype
value should be the same as the customizer attribute you're linking, andstring_value
is the value that you want the Google Ads API to use.- Resource name of the resource you want to link the customizer attribute to
The name varies based on the resource type. For instance, to create
CampaignCustomizer
, specify thecampaign
.
Once you finish this step, you're ready to use the ad customizer in responsive
search ads that are included in the resource hierarchy you linked the
customizer attribute to. For instance, if you link the customizer attribute to
the campaign with an ID A
, you can use that ad customizer in an ad created
under any ad groups inside campaign A
. You cannot use the ad customizer in an
ad under ad groups inside campaign B
.
Ad customizers in responsive search ads
To use the ad customizer in headlines and description of the responsive
search ads, you need to create an AdTextAsset
object with text
including the following syntax:
{CUSTOMIZER.CUSTOMIZER_ATTRIBUTE_NAME:DEFAULT_VALUE}
CUSTOMIZER_ATTRIBUTE_NAME
is thename
of the customizer attribute that you set when you created it, not the resource name of the customizer attribute nor its ID.DEFAULT_VALUE
is the default value for the ad customizer.
Refer to the responsive search ads guide for more information about setting up the ads.
Rules and limitations
There can only be one link per level—customer, campaign, ad group, or ad group criterion—and the most specific one will override the more general one. For example, if you have this customizer attribute defined at the campaign level and the ad group level, then ads within the linked ad group will use the ad group one, but ads from other ad groups in that campaign will use the campaign one.
You can have up to 40 enabled
CustomizerAttribute
objects in your account. If you reach this limit, you need to remove the unused ones before creating a new one.There are rules for customizer attributes with type
