Manage Offline Conversions

You can use the Google Ads API to import offline conversions into Google Ads in order to track ads that led to sales in the offline world, such as over the phone or through a sales rep.

In order to fully take advantage of the benefits of importing conversion data, we recommend implementing enhanced conversions for leads, which leverages GCLIDs and user-provided data to maximize durability and performance.

Note: If you're unable to gather and import user-provided data, you can implement legacy offline conversion imports by following the Legacy Offline Conversion Imports Guide.

Enhanced conversions

Enhanced conversions help you to improve the accuracy of your conversion measurement by supplementing your conversions with first-party conversion data, like email address, name, home address, and phone number.

There are two types of enhanced conversions. For more details see the About enhanced conversions Help Center article.

The following section explains how to enhance offline conversions, a feature also referred to as enhanced conversions for leads.

What is enhanced conversions for leads?

Enhanced conversions for leads is an upgraded version of offline conversion import that uses user-provided data, such as email addresses, to supplement imported offline conversion data to improve accuracy and bidding performance. When you import your offline conversions, the provided hashed customer data is used to attribute back to the Google Ads campaign by matching to the same data collected on your website, such as a, lead form, and to signed-in customers who engaged with your ad. For more information about how enhanced conversions for leads works, review our article; About enhanced conversions for leads.

There are two ways to implement enhanced conversions for leads depending on whether you use the Google tag to track form submission events on your webpage. For the best performance and durability, we strongly recommend using Google tag for enhanced conversions for leads.

• If you are starting from scratch, start with the Prerequisites section.
• If you already have offline conversion imports set up, and want to upgrade to enhanced conversions for leads, we recommend starting with the Configure tagging section.
• If you've already set up the Google tag, or don't plan to use the Google tag, and are starting work on your Google Ads API integration, jump to the API Implementation section.
• If you are unable to import user-provided data, or rely on external attribution for your conversions, see the Legacy Offline Conversion Imports Guide.

Prerequisites

First, ensure you've completed the steps in our getting started section.

You must opt in to enhanced conversions for leads and accept the customer data terms before you can use enhanced conversions for leads. You can verify whether these prerequisites are already met by issuing the following query to the Google Ads conversion customer:

SELECT
  customer.id,
  customer.conversion_tracking_setting.accepted_customer_data_terms,
  customer.conversion_tracking_setting.enhanced_conversions_for_leads_enabled
FROM customer

If either of accepted_customer_data_terms or enhanced_conversions_for_leads_enabled is false, follow the instructions in the Help Center to complete these prerequisites.

Configure tagging

Configure the Google tag to enable enhanced conversions for leads by following the instructions in Help Center. To set up enhanced conversions for leads with Google Tag Manager, follow these instructions.

API Implementation

Here is the overall flow for importing enhanced conversions for leads using the Google Ads API.

1. Normalize and hash the user-provided data, such as email address, phone number, and mailing address.

2. Populate ClickConversion objects with the normalized and hashed user-provided data.

3. Import ClickConversion objects to the Google Ads API using the ConversionUploadService.

4. Review your imports.

Normalize and hash user-provided data

For privacy considerations, the following data must be hashed using SHA-256 before being imported:

• Email address
• Phone number
• First name
• Last name
• Street address

In order to standardize the hash results, you must do the following prior to hashing these values:

• Remove leading and trailing whitespaces.
• Convert the text to lowercase.
• Format phone numbers according to the E164 standard.
• Remove all periods (.) that precede the domain name in gmail.com and googlemail.com email addresses.

Don't hash the following data:

• Country
• State
• City
• Zip code

Code example

This example shows how to normalize and hash user-provided data.

Java

private String normalizeAndHash(MessageDigest digest, String s)
    throws UnsupportedEncodingException {
  // Normalizes by first converting all characters to lowercase, then trimming spaces.
  String normalized = s.toLowerCase();
  // Removes leading, trailing, and intermediate spaces.
  normalized = normalized.replaceAll("\\s+", "");
  // Hashes the normalized string using the hashing algorithm.
  byte[] hash = digest.digest(normalized.getBytes("UTF-8"));
  StringBuilder result = new StringBuilder();
  for (byte b : hash) {
    result.append(String.format("%02x", b));
  }

  return result.toString();
}

/**

Populate ClickConversion objects

The collection of ClickConversion objects in your UploadClickConversionRequest represents the set of conversions you want to import. Keep the following details in mind when creating ClickConversion objects:

gclid

GCLIDs are click identifiers that are captured from URL parameters when an individual clicks on your ad and navigates to your website.

Important: We recommend including GCLIDs in your import requests where possible, even if you have Google Tag set up to track enhanced conversions for leads.

user_identifiers

When using enhanced conversions for leads, you must populate the user_identifiers field with normalized and hashed user-provided data. If you have multiple user identifiers available, create a separate UserIdentifier for each one, up to five identifiers.

Important: you can, and should, send all relevant data for a given conversion, even if you don't have a GCLID for it. Conversions that include only user-provided data are still useful and can contribute positively to campaign optimization.

conversion_date_time

The date and time of the conversion.

The value must have a timezone specified, and the format must be yyyy-mm-dd HH:mm:ss+|-HH:mm, for example: 2022-01-01 19:32:45-05:00 (ignoring daylight saving time) .

The timezone can be for any valid value: it does not have to match the account's timezone. However, if you plan on comparing your imported conversion data with those in the Google Ads UI, we recommend using the same timezone as your Google Ads account so that the conversion counts match. You can find more details and examples in the Help Center and check the Codes and formats for a list of valid timezone IDs.

Note: If you're importing conversions for Commissions (pay-per-conversion) for Hotel ads, you can only import conversions for clicks that occurred in the same month. Conversions imported after 4 AM Pacific Time (PT) on the first day of the following month of when the click happened are ignored.

conversion_action

The resource name of the ConversionAction for the offline conversion.

The conversion action must have a type of UPLOAD_CLICKS, and must exist in the Google Ads conversion customer of the Google Ads account associated with the click.

conversion_value

The value of the conversion.

currency_code

The currency code of the conversion_value.

consent

It's highly recommended that you populate the consent field of the ClickConversion object. If not set, it's possible that your conversions won't be attributable.

order_id

Also known as the transaction ID for the conversion. This field is optional, but strongly recommended, because it makes it simpler to reference imported conversions when making adjustments. If you set it during the import, you must use it for any adjustments. To learn more about how to use a transaction ID to minimize duplicate conversions, see this Help Center article.

custom_variables

The values for custom conversion variables.

Google Ads does not support custom conversion variables in combination with wbraid or gbraid.

conversion_environment

Indicates the environment where this conversion was recorded. For example, APP or WEB.

session_attributes_encoded and session_attributes_key_value_pairs

Session attributes represent aggregated identifiers used for conversion attribution. These work in addition to click identifiers, (such as GCLIDs and GBRAIDs), and user-provided data, which is central to enhanced conversions for leads. There are two ways to import session attributes: by providing the encoded token generated by our Javascript code in the browser, or by providing individual key value pairs for each of the identifiers.

To maximize your campaign performance, we recommend importing click identifiers, user-provided data, and session attributes with all of your conversions, if possible.

Java

// Sets one of the sessionAttributesEncoded or sessionAttributesKeyValuePairs if either is
// provided.
if (rawRecord.containsKey("sessionAttributesEncoded")) {
  clickConversionBuilder.setSessionAttributesEncoded(
      ByteString.copyFromUtf8(rawRecord.get("sessionAttributesEncoded")));
} else if (rawRecord.containsKey("sessionAttributesMap")) {

}
upload_enhanced_conversions_for_leads.pl
      

user_ip_address

The IP address of the customer when they arrived on the landing page after an ad click and before a conversion event. This is the IP address of the customer's device, not the advertiser's server.

This field is a string representing an IP address in either IPv4 or IPv6 format. For example:

• IPv4: "192.0.2.0"
• IPv6: "2001:0DB8:1234:5678:9999:1111:0000:0001"

Note: Google Ads does not support IP address matching for end users in the European Economic Area (EEA), United Kingdom (UK), or Switzerland (CH). Add logic to conditionally exclude sharing IP addresses from users from these regions and ensure that you provide users with clear and comprehensive information about the data you collect on your sites, apps, and other properties and get consent where required by law or any applicable Google policies. See the About offline conversion imports page for more details.

Code example

Construct the request

Once your ClickConversion objects are configured and added to the conversions field of the UploadClickConversionRequest object, set the following fields and pass the request to the UploadClickConversions method on the ConversionUploadService.

customer_id

Set this to the Google Ads conversion customer of the account that is the source of the clicks. If you're unsure which account is the correct one, refer to the customer.conversion_tracking_setting.google_ads_conversion_customer field in the example query in the getting started section.

job_id

Provides a mechanism for associating your import requests with the per-job information in offline data diagnostics.

If you don't set this field, the Google Ads API assigns each request a unique value in the range of [2^31, 2^63). If you would prefer to group multiple requests into a single logical job, set this field to the same value in the range [0, 2^31) on every request in your job.

The job_id in the response contains the job ID for the request, regardless of whether you specified a value or let the Google Ads API assign a value.

partial_failure

This field must be set to true when importing conversions. Follow the partial failures guidelines when processing the response.

Import the request

Once you've populated your ClickConversion objects, and constructed your request, you can submit your import.

Review your imports

Use the enhanced conversions for leads diagnostics report to review the overall health of your recent imports.

Important: A successful import response from the API does not necessarily mean the conversions have been attributed. See this Help Center article for more details on data discrepancies after a successful import.

Imported conversions are reflected in reports for the impression date of the original click, not the date of the import request or the date of the conversion_date_time of the ClickConversion.

It takes up to three hours for imported conversion statistics to appear in your Google Ads account for last-click attribution. For other search attribution models, it can take longer than three hours. Consult the data freshness guide for more information.

When reporting on conversion metrics for your campaigns, refer to Mapping user interface metrics to correlate Google Ads UI metrics with Google Ads API reporting fields. You can also query the conversion_action resource to view the total number of conversions and the total conversion value for a given conversion action.

Best practices

Keep the following best practices in mind when implementing enhanced conversions for leads.

Send all conversion data regardless of completeness

To ensure full and accurate conversion reporting, import all available offline conversion events, including those that might not have come from Google Ads. Conversions that include only user-provided data are still useful and can contribute positively to Google Ads campaign optimization.

If you assign an order_id to a conversion, we recommend including it. If you have the GCLID for a conversion, we recommend sending it in addition to the user_identifiers for improved performance. Furthermore, if you have more than one UserIdentifier for the conversion, include all of them on the ClickConversion object to improve the likelihood of a match.

Batch multiple conversions in a single request

If you have multiple conversions to import, batch the conversions into one UploadClickConversionsRequest, rather than sending an import request per conversion.

Check the quota guide for limits on the number of conversions per request.

If you want offline data diagnostics to group a set of requests under the same logical job, set the job_id of all the requests to the same value. This can be useful if you have a single job or process that imports a large number of conversions using multiple requests. If you set the job_id on each of those requests to the same value, then you can retrieve a single entry for the job from job_summaries. If instead you let the Google Ads API assign a system-generated value to the job_id of each request, the job_summaries contains a separate entry for each request, which could make analyzing the overall health of your job more challenging.

Don't use external attribution data

When using enhanced conversions for leads, don't set external_attribution_data on the ClickConversion or specify a conversion_action that uses an external attribution model. Google Ads doesn't support externally attributed conversions for imports using user-provided data.

Don't include custom variables

When using enhanced conversions for leads, don't include any custom_variables. Google Ads doesn't support the use of custom variables with user-provided data in conversion imports. If custom variables are included with conversions that contain user-provided data, those conversions will be considered invalid and dropped.

Troubleshooting

Offline data diagnostics provide a single resource for reviewing the overall health of your imports on an ongoing basis. However, during implementation you can use the information in this section to investigate any errors reported in the partial_failure_error field of the response.

Some of the most common errors when importing conversion actions are authorization errors, such as USER_PERMISSION_DENIED. Double check that you have the customer ID in your request set to the Google Ads conversion customer which owns the conversion action. Visit our authorization guide for more details and see our common errors guide for tips on how to debug these different errors.

Debug common errors

Error
NO_CONVERSION_ACTION_FOUND	The specified conversion action is either not enabled, or cannot be accessed by the client account specified by the `client_id` field in the request. Make sure the conversion action in your upload is enabled and is owned by the customer sending the upload request. This error may also occur if the GCLID in the request belongs to a client account that does not have access to the conversion action specified in the request. You can verify whether a GCLID belongs to a client account using the click_view resource, by submitting a query that filters by click_view.gclid and segments.date, where the date is the date the click occurred.
INVALID_CONVERSION_ACTION_TYPE	The specified conversion action has a type that is not valid for enhanced conversions for leads. Make sure the ConversionAction specified in your upload request has type UPLOAD_CLICKS.
CUSTOMER_NOT_ENABLED_ENHANCED_CONVERSIONS_FOR_LEADS	Make sure you've enabled enhanced conversions for leads in your conversion settings. Find instructions for this in the prerequisites guide.
DUPLICATE_ORDER_ID	Imported events include multiple conversions with the same Order ID and were not processed. Make sure Order IDs are unique and try again.
CLICK_NOT_FOUND	No click was found that matched the provided user identifiers. The Google Ads API only returns this error if debug_enabled is true on the UploadClickConversionsRequest. Note: Treat this error as a warning unless it occurs with the majority of your conversions. If a conversion encounters this warning, the Google Ads API includes it in the successful_event_count of your offline data diagnostics. The Google Ads API includes an entry for CLICK_NOT_FOUND in the alerts collection so you can monitor the frequency of this warning. This error is expected if the click is not from a Google Ads campaign. For example it may come from SA360 or DV360. Other possible causes are as follows: The uploading customer is different from the Google Ads conversion customer. Tagging is not correctly configured for your lead form. The uploaded data has not been correctly normalized and hashed. In rare instances where the uploading customer is different from the Google Ads conversion customer, this error can mean that the uploading customer has accepted the customer data terms, but the serving customer has not. You can determine if an account has accepted the customer data terms by querying the customer resource and checking the customer.offline_conversion_tracking_info.accepted_customer_data_terms field.
