Tracking and Importing Conversions

A conversion in Google Ads is when a user performs some specified action after clicking an ad or viewing a Display Network ad, such as purchasing a product, installing a mobile app, or signing up for an email list.

Conversion tracking provides key insights into users' actions after viewing or clicking an ad. You can keep track of users who call, buy a product, install a mobile app, and more. Google Ads provides different conversion trackers for the different ways customers convert.

This guide describes the different types of conversion trackers and how to apply them. It also describes how to use the API to import offline conversions into Google Ads.

Types of conversion trackers

To measure conversions, you set up a ConversionTracker for the type of conversion actions you want to track. For instance, an online purchase and a phone call require different conversion trackers.

Most conversion types also require additional actions on your part to track them. For instance, tracking conversion actions on your website requires creation of an AdWordsConversionTracker and a code snippet called a tag that you add to the conversion page on your website.

Note that conversion sources related to calls in the Google Ads UI (Phone number clicks, Calls from ads, and Calls from websites) are each mapped to a different ConversionTracker in the AdWords API:

• Phone number clicks corresponds to AdWordsConversionTracker (with trackingCodeType as CLICK_TO_CALL).
• Calls from ads corresponds to AdCallMetricsConversion.
• Calls from websites corresponds to WebsiteCallMetricsConversion.

The following sections describe the different types of conversion trackers.

Conversions on websites

The AdWordsConversionTracker encompasses several types of website conversions, distinguished within the API by the trackingCodeType field.

The table below shows the equivalent API parameters to use for each Source in the Google Ads UI:

trackingCodeType	Google Ads UI Source
WEBPAGE	Website
WEBPAGE_ONCLICK	Website
CLICK_TO_CALL	Phone number clicks
---	Analytics

Note: WEBPAGE and WEBPAGE_ONCLICK have the same UI source as Website. The difference is in the Event snippet option in the UI. WEBPAGE corresponds to Page load for this option, whereas WEBPAGE_ONCLICK corresponds to Click.

Website and Phone number clicks conversions require the googleEventSnippet, which should be placed on web pages that indicate a conversion action such as a checkout confirmation or lead submission page, and googleGlobalSiteTag, which must be installed on every page of your website. You can retrieve both of these attributes with ConversionTrackerService.

The CLICK_TO_CALL type differs from AdCallMetricsConversion in that it does not track actual phone calls. Instead, it tracks only clicks on a phone number from a mobile device. This is useful when you're unable to use a Google forwarding number for tracking actual phone calls.

Note: Analytics goals and transactions created in Google Analytics profiles linked to this Google Ads account are returned with no trackingCodeType. They have a status of HIDDEN if they haven't been imported into Google Ads. The status of conversion trackers cannot be changed via the API; they can only be imported using the Google Ads UI.

Phone call conversions

Tracking phone calls from call extensions requires an AdCallMetricsConversion tracker. These use a Google forwarding number and specify the conversion tracker in the phone call extension's FeedItem. In the Google Ads UI, this type of conversion is called Calls from ads.

You track this conversion type by specifying the tracker in the phone call extension's FeedItem using the placeholder type for CONVERSION TYPE ID.

A call is reported as a conversion if it lasts longer than a specified duration. The default is 60 seconds.

App conversions

An AppConversion covers both mobile app installs and in-app actions, for Android and iOS. The table below shows the equivalent API parameters to use for each Source in the Google Ads UI:

appPlatform	appConversionType	Google Ads UI Source
ITUNES	FIRST_OPEN	iOS app install (first open)
ITUNES	IN_APP_PURCHASE	iOS in-app action
ANDROID_MARKET	DOWNLOAD	Android app install (from Google Play)
ANDROID_MARKET	FIRST_OPEN	Android app install (first open)
ANDROID_MARKET	IN_APP_PURCHASE	Android in-app action

Note: If you're also specifying the category field, set it to DOWNLOAD only if the appConversionType is DOWNLOAD or FIRST_OPEN.

When you specify FIRST_OPEN as the appConversionType, you can provide an appPostbackUrl to get instant confirmation when a user first opens your app. See the Android mobile app conversion tracking guide for more details.

Upload click conversions

An UploadConversion maps to the Import conversion source in the Google Ads UI followed by Conversion from clicks. When they're created in the web interface, auto-tagging is automatically enabled for the account, but this does not occur when you create the conversion tracker via the API. If you create a conversion tracker using the API, you should enable auto-tagging using CustomerService. Without auto-tagging you won't get the GCLID parameter required to upload conversions corresponding to a click.

Once you create an UploadConversion, you can use the OfflineConversionFeedService to upload conversions for clicks. See Importing Click Conversions below for details.

Upload call conversions

An UploadCallConversion maps to the Import conversion source in the Google Ads UI followed by choosing Conversion from calls.

A mobile click-to-call click cannot be uploaded as a conversion if there is no Google forwarding number attached to the call. Without a Google forwarding number, there is no way Google can be sure that the click led to a call and then to a conversion. If a click is uploaded like this, it will be ignored by the conversion tracker.

Once you create an UploadCallConversion, you can use the OfflineCallConversionFeedService to upload conversions for calls. See Importing Call Conversions below for details.

Calls from websites

A WebsiteCallMetricsConversion maps to Calls from a website in the Google Ads UI.

Unlike AdCallMetricsConversion, this tracker requires googleEventSnippet and googleGlobalSiteTag to be added to your website to retrieve the dynamic Google forwarding number for call tracking on numbers listed on your website. In addition, you must set up a call extension and attach it to the campaign or ad groups whose website calls you want to track.

Store Sales Direct conversions

Note: This feature is available only on a whitelist basis.

Store Sales Direct Uploads allows you to import offline transactions in Google Ads either directly or through third-party partners. By matching transaction data from your point-of-sale systems or customer database, you can see how your Google ads translate into offline purchases. The offline transactions can be uploaded in an OfflineDataUpload object through the OfflineDataUploadService.

System-wide default conversion trackers

Google Ads provides some system-wide default conversion trackers that don't require tags. These trackers have default settings for various fields including name, value, etc.

If you want to edit the settings for these default conversion trackers, you must do so through the Google Ads UI. If you try to edit these kinds of conversion trackers in the API, the API will throw an INVALID_ORIGINAL_CONVERSION_TYPE_ID error.

Cross-account conversion tracking

If you're using cross-account conversion tracking, the ConversionTrackerService returns the following conversion types:

1. All conversion types defined by the manager account used by the account for cross-account conversion tracking.
2. All conversion types on which the customer has accrued stats, including system-defined types, and types owned by the manager even if that manager unlinks subsequently.
3. All types the customer has defined in their own account, including Analytics goals and transactions created in linked Google Analytics profiles. This includes types not imported into Google Ads, which will have a status of HIDDEN and can only be imported using the Google Ads UI.

You can set up and query cross-account conversion trackers via the API, but you must opt in your accounts to cross-account conversion tracking from the manager account. See this help center article for more information.

In the past, the Conversions column contained only those conversions that occurred on the same device. Now you can choose to include cross-device conversions in the Conversions column using the optimizeOnEstimatedConversions property of the customer's conversion tracking settings. These conversions will then be used by various automated bid strategies that optimize for conversions, such as target cost per acquisition (CPA), target return on ad spend (ROAS), or enhanced cost per click (ECPC).

Conversion fields available in reporting

You can retrieve conversion stats for your accounts, campaigns, or ad groups using conversion fields available in reports.

The tables below lists some commonly used report fields related to conversions.

Conversions and its derivative fields

Field Name	Description
Conversions	Main field for conversions reporting that reflects conversion actions you want to bid on. Only conversions from conversion actions (ConversionTracker) that have the excludeFromBidding field set to false are included.
ConversionRate	Conversions divided by total clicks that can be conversion-tracked. This is how often, on average, an ad interaction leads to a conversion that has the excludeFromBidding field set to false.
ConversionValue	The total value of all conversion actions (ConversionTracker) that have the excludeFromBidding field set to false.
CostPerConversion	Total cost divided by Conversions.
ValuePerConversion	ConversionValue divided by Conversions.

AllConversions and its derivative fields

Field Name	Description
AllConversions	Includes all conversions from Google Ads, regardless of the values of excludeFromBidding. All conversion sources (website, cross-device, phone calls, etc.) contribute to the count.
AllConversionRate	AllConversions divided by total clicks that can be conversion-tracked. This is how often, on average, an ad interaction leads to a conversion.
AllConversionValue	The total value of all of your conversions. Includes website, cross-device, phone call conversions and conversion actions (ConversionTracker) regardless of the values of excludeFromBidding.
CostPerAllConversion	Total cost divided by AllConversions.
ValuePerAllConversion	AllConversionValue divided by AllConversions.

CrossDeviceConversions

Field Name	Description
CrossDeviceConversions	Conversions in which a customer interacts with an ad (for example, by clicking a text ad or viewing a video ad) on one device, then converts on a different device or browser. CrossDeviceConversions is already included in the AllConversions field.

Current Model columns associated with Conversions

When you change the attributionModelType field for a conversion action in Google Ads, it only changes the way your conversions are counted in your Conversions and All conversions columns going forward. If you want to see how your historic conversions data would look with the attribution model you’ve just selected, you can use the Current Model columns listed below. By comparing these columns with the regular conversion tracking columns, you can see how your data would have differed if you had been using the current attribution model.

Field Name	Description
CostPerCurrentModelAttributedConversion	Historical CostPerConversion data based on the current attribution model.
CurrentModelAttributedConversionValue	Historical ConversionValue data based on the current attribution model.
CurrentModelAttributedConversions	Historical Conversions data based on the current attribution model.
ValuePerCurrentModelAttributedConversion	Historical ValuePerConversion data based on the current attribution model.

Conversion attribution in reports

Key Point: Reports attribute conversion metrics by impression date.

The date of a conversion and the date on which you uploaded a conversion have no impact on the date on which reports will reflect the conversion and its values. All metrics in reports are attributed to the impression date of each click.

For example, let's say that on October 21, 2017 you upload the following conversions, all with a conversionTime where the date portion is 20171020:

ImpressionDate	Conversions	ConversionValue
October 18, 2017	500	$1,000
October 19, 2017	250	$200
October 20, 2017	100	$150

In that case, the Conversions and ConversionValues for a report for October 20, 2017 will only change by 100 and $150, respectively. To see the changes in Conversions and ConversionValues for all of the uploaded conversions, you would have to expand the report date range to cover October 18, 2017 through October 20, 2017.

Similarly, the Conversions and ConversionValue metrics for October 21, 2017 (the date on which you uploaded the conversions) will not change as a result of the upload.

Importing click conversions

Note: AdWords API limits the number of conversions you can upload per mutate call.

You can use the AdWords API to upload offline conversions into Google Ads, giving you more flexibility in associating clicks with conversions. You can track ads that led to sales in the offline world, such as over the phone or via a sales rep.

This section describes how to use the AdWords API to construct a feed for importing your offline conversions.

Setup

The first step is to create import conversion types. This must be done for each unique conversion "classification". You can create them using the Google Ads UI or through code:

Java

// Create an upload conversion for offline conversion imports.
UploadConversion uploadConversion = new UploadConversion();
// Set an appropriate category. This field is optional, and will be set to
// DEFAULT if not mentioned.
uploadConversion.setCategory(ConversionTrackerCategory.LEAD);
uploadConversion.setName("Upload Conversion #" + System.currentTimeMillis());
uploadConversion.setViewthroughLookbackWindow(30);
uploadConversion.setCtcLookbackWindow(90);

// Optional: Set the default currency code to use for conversions
// that do not specify a conversion currency. This must be an ISO 4217
// 3-character currency code such as "EUR" or "USD".
// If this field is not set on this UploadConversion, AdWords will use
// the account's currency.
uploadConversion.setDefaultRevenueCurrencyCode("EUR");

// Optional: Set the default revenue value to use for conversions
// that do not specify a conversion value. Note that this value
// should NOT be in micros.
uploadConversion.setDefaultRevenueValue(2.50);
// Optional: To upload fractional conversion credits, mark the upload conversion
// as externally attributed. See
// https://developers.google.com/adwords/api/docs/guides/conversion-tracking#importing_externally_attributed_conversions
// to learn more about importing externally attributed conversions.

// uploadConversion.setIsExternallyAttributed(true);

conversionTrackers.add(uploadConversion);

PHP

// Create an upload conversion for offline conversion imports.
$uploadConversion = new UploadConversion();
// Set an appropriate category. This field is optional, and will be set to
// DEFAULT if not mentioned.
$uploadConversion->setCategory(ConversionTrackerCategory::LEAD);
$uploadConversion->setName('Upload Conversion # ' . uniqid());
$uploadConversion->setViewthroughLookbackWindow(30);
$uploadConversion->setCtcLookbackWindow(90);

// Optional: Set the default currency code to use for conversions
// that do not specify a conversion currency. This must be an ISO 4217
// 3-character currency code such as "EUR" or "USD".
// If this field is not set on this UploadConversion, AdWords will use
// the account's currency.
$uploadConversion->setDefaultRevenueCurrencyCode('EUR');

// Optional: Set the default revenue value to use for conversions
// that do not specify a conversion value. Note that this value
// should NOT be in micros.
$uploadConversion->setDefaultRevenueValue(2.50);

// Optional: To upload fractional conversion credits, mark the upload
// conversion as externally attributed. See
// https://developers.google.com/adwords/api/docs/guides/conversion-tracking#importing_externally_attributed_conversions
// to learn more about importing externally attributed conversions.

// uploadConversion->setIsExternallyAttributed(true);

conversionTrackers.Add(uploadConversion)

This snippet creates an UploadConversion object using the ConversionTrackerService. The given conversionName is used to identify this conversion event, and must be unique.

After creating your import conversion types, you must enable your website and lead-tracking system to capture and store the GCLID, the unique ID that Google Ads provides for every impression of a Google ad and is sent to the Google server when the ad is clicked. You also must enable auto-tagging so your website will start receiving the GCLID as a URL parameter. For more details about these steps, see Tracking Offline Conversions.

Note: Setup needs to be done only once, whereas the upload process described below can be repeated as often as required.

Uploading offline conversions

Once you've created the UploadConversion object, you need to associate your offline conversions with it by passing the GCLID, conversion time (with timezone ID), conversion name, and optionally the conversion value and conversion currency to OfflineConversionFeedService:

Java

/**
 * Runs the example.
 *
 * @param adWordsServices the services factory.
 * @param session the session.
 * @param conversionName the name of the conversion tracker.
 * @param gClid the GCLID for the conversion.
 * @param conversionTime the date and time of the conversion.
 * @param conversionValue the value of the conversion.
 * @throws ApiException if the API request failed with one or more service errors.
 * @throws RemoteException if the API request failed due to other errors.

Importing externally attributed conversions

If you use third-party tools or homegrown solutions to track conversions, then you may want to give Google Ads only part of the credit for the conversion. Sometimes, you may also want to distribute a conversion's credit across multiple clicks. Externally attributed conversion imports allows you to upload conversions with fractional credit assigned to each gclid.

To upload fractional credits, you need to follow the instructions for uploading offline conversions, and perform these additional steps:

1. When creating your UploadConversion object, mark it as externally attributed by setting the isExternallyAttributed property to true.

2. Specify the externalAttributionModel and externalAttributionCredit properties for your OfflineConversionFeed object when uploading conversions.

Validation rules

There are several requirements that must be met when uploading an OfflineConversionFeed.

To avoid an OfflineConversionError.INVALID_CONVERSION_TYPE error, the conversionName must refer to an UploadConversion where:

• The UploadConversion had a status of ENABLED at the time of the click.

• The UploadConversion existed in the effective conversion account of the click's Google Ads account at the time of the click. If the account was not using cross-account conversion tracking at the time of the click, Google Ads will look for the UploadConversion in the account used to upload conversions. You can find your account's effective conversion tracking account under Tools > Conversions in the Google Ads UI, but keep in mind that this will show you the current effective conversion tracking account, which may differ from the effective conversion tracking account in place at the time of the click.

In addition, the following conditions must be met:

• The conversionTime must be after the click happened, to avoid an OfflineConversionError.CONVERSION_PRECEDES_CLICK error.

• The conversionTime must be before the click-through conversion lookback window you specified for the UploadConversion object, to avoid an OfflineConversionError.EXPIRED_CLICK error.

• The conversionValue must be greater than or equal to zero.

• The conversionTime must have a timezone ID. The timezone ID can be for any valid timezone: It does not have to match the account's timezone.

Tips

A few things to keep in mind when creating an OfflineConversionFeed:

• Upload operations are atomic; if a conversion has a bad GCLID or is too old, none of the accompanying conversions will be uploaded. Use partial failures to avoid this situation.

• Although duplicate uploads of a conversion (same GCLID, name, and time) are permitted, only the first instance is recorded.

• Uploaded conversions will be reflected in reports for the impression date of the original click, not the date of the upload request or the date of the conversionTime of the OfflineConversionFeeds.

• We recommend you wait 6 hours after creating the UploadConversion before uploading.

• It takes up to 3 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 3 hours.

• When uploading click conversions for multiple accounts, you can specify the clientCustomerId of a common manager account and include operations with GCLIDs from across multiple accounts. A conversion is attributed to the proper account based on the origin of its GCLID.

• When uploading click conversions with cross-account conversion tracking enabled, the conversion type must be in the manager account, rather than in the account associated with the GCLID.

Importing call conversions

You can use the AdWords API to upload offline call conversions into Google Ads, giving you more flexibility in associating calls with conversions.

This section describes how to use the AdWords API to construct a feed for importing your offline call conversions.

Setup

The first step is to create a conversion tracker for offline call conversions. You can create one using the Google Ads UI or through code. Through code you would create an UploadCallConversion. The process is similar to the example found in Setup for importing click conversions. In the example, use UploadCallConversion instead of UploadConversion.

Note: Setup needs to be done only once, whereas the upload process described below can be repeated as often as required.

Uploading offline call conversions

Once you've created the UploadCallConversion object, you need to associate your offline call conversions with it by passing the caller ID, conversion time (with timezone ID), conversion name, and optionally the conversion value and conversion currency to OfflineCallConversionFeedService:

Java

/**
 * Runs the example.
 *
 * @param adWordsServices the services factory.
 * @param session the session.
 * @param callerId the caller ID of the call.
 * @param callStartTime the call start time of the call.
 * @param conversionName the name of the conversion tracker.
 * @param conversionTime the date and time of the conversion.
 * @param conversionValue the value of the conversion.
 * @throws ApiException if the API request failed with one or more service errors.
 * @throws RemoteException if the API request failed due to other errors.

Validation rules

There are several requirements that must be met when uploading an OfflineCallConversionFeed.

To avoid an OfflineCallConversionError.INVALID_CONVERSION_TYPE error, the conversionName must refer to an UploadCallConversion where:

• The UploadCallConversion had a status of ENABLED at the time of the call.

• The UploadCallConversion existed in the effective conversion account of the call's Google Ads account at the time of the call. If the account was not using cross-account conversion tracking at the time of the call, Google Ads will look for the UploadCallConversion in the account used to upload conversions. You can find your account's effective conversion tracking account under Tools > Conversions in the Google Ads UI, but keep in mind that this will show you the current effective conversion tracking account, which may differ from the effective conversion tracking account in place at the time of the call.

In addition, the following conditions must be met:

• The conversionValue must be greater than or equal to zero.

• The conversionTime must have a timezone ID. The timezone ID can be for any valid timezone: It does not have to match the account's timezone.

Tips

A few things to keep in mind when creating an OfflineCallConversionFeed:

• We recommend you wait 6 hours after creating the UploadCallConversion before uploading.

• It takes up to 3 hours for imported conversion statistics to appear in your Google Ads account.

• Although duplicate uploads of a conversion (same caller ID, name, and time) are permitted, only the first instance is recorded.

Adjusting conversions

Once a conversion has already been reported to Google Ads, you can adjust the conversion at a later point in time in the API.

Setup

In order to adjust a conversion, you must first have conversion tracking set up, and you must also have reported on the conversions that you are about to adjust.

Uploading conversion adjustments

There are two types of adjustments that can be made. When you have a Google click ID (GCLID) and conversion time available, you can adjust a conversion by uploading a GclidOfflineConversionAdjustmentFeed object. You can also adjust a conversion by uploading an OrderIdOfflineConversionAdjustmentFeed object when you have an order ID available instead of a click ID and conversion time. Both these adjustment types would be uploaded through the OfflineConversionAdjustmentFeedService.

Validation rules

Here are some things to keep in mind while adjusting conversions in the API:

• You can upload to other conversion types that are not traditionally supported by the API as long as you have the conversion tracker name.
• Only the account that manages conversion types for accounts under it will be able to upload adjustments.
• The fields specifying time require a time zone ID which does not need to be that of the account.
• The conversion has to already be reported in order to adjust it.

The first step is to create import conversion types. This must be done for each unique conversion "classification". You can create them only using the Google Ads UI. The given conversionName is a unique identifier for this conversion event. After creating your import conversion types, you are ready to start uploading Store Sales Direct conversions using either the UI or the AdWords API.

Uploading Store Sales Direct conversions

Once you've created the conversion tracker, you need to associate Store Sales Direct conversions with it by passing the conversion name and store transactions in the OfflineDataUpload object through the OfflineDataUploadService.

Validation rules

There are several requirements that must be met when uploading an OfflineDataUpload object.

To avoid an OfflineDataUploadError.INVALID_CONVERSION_TYPE error, the conversionName must refer to a conversion tracker where:

• The conversion tracker was enabled at the time of the click.

• The conversion tracker existed in the effective conversion account of the click's Google Ads account at the time of the click. If the account was not using cross-account conversion tracking at the time of the click, Google Ads will look for the conversion tracker in the account used to upload conversions. You can find your account's effective conversion tracking account under Tools > Conversions in the Google Ads UI, but keep in mind that this will show you the current effective conversion tracking account, which may differ from the effective conversion tracking account in place at the time of the click.

In addition, the following conditions must be met:

• The transactionAmount must be greater than zero.

• The transactionTime must have a timezone ID. The timezone ID can be for any valid timezone: It does not have to match the account's timezone.
