About offline conversion tracking

Sometimes, an ad doesn't lead directly to an online sale, but instead starts a customer down a path that ultimately leads to a sale in the offline world, such as at your office or over the phone. By importing offline conversions, you can measure what happens in the offline world after your ad results in a click or call to your business.


Importing offline conversion events gives you a more comprehensive look at which keywords and targeting criteria (for example, geography or time of day) drive the most cost-effective conversions. This data can help you target and optimize your campaigns for increased profit.

If you attract leads or buyers online, or both, you might want to record a conversion in the following cases:

  • When you close a sale offline (for example, over the phone or in person) and track this sale in a customer relationship manager system
  • 30 days after the online sale so you can exclude transactions that resulted in a return
  • Only if the sale was made to a new customer
  • Only if it is a customer's 2nd purchase
  • When you close a sale online but are unable to use our standard Javascript-based conversion tracking solution

Here's a quick overview of the feature.

Types of offline conversion tracking

Google Ads offers 2 options to see how your Google Ads campaigns drive offline sales and leads:

  • Google Ads Conversion Import allows you to import conversions that you track in any other system into Google Ads. It’s the broadest option and applies to many different ways of tracking offline conversions. And it allows you to import conversions that started with an ad click or with a call from your ad
  • Google Ads Conversion Import for Salesforce® allows you to  automatically see when sales events that you track in Salesforce started with a click on an ad. It's the best option if you use Salesforce’s Sales Cloud® to track your sales data. You can learn more about the specifics for this solution in About Google Ads Conversion Import for Salesforce.

How it works

Offline conversion tracking works a little differently depending on whether you’re tracking conversions that start with an ad click or call from your ad.

Conversions from clicks

Google Ads provides you with a unique ID, called a "GCLID," for every click that comes to your website from an ad. To track offline conversions, you'll save that ID along with whatever lead information you collect from the person who clicked your ad.

Later, when that person "converts" in the offline world, by signing a contract, for example, you give that GCLID back to Google Ads along with a few details about the type of conversion it was and when it happened. Then Google Ads records this conversion along with your other conversion tracking data.


You design, build, and sell custom boardroom tables. You use Google Ads to drive prospective customers to your website, where they then can submit their contact information and request a sales call. If a lead results from a click on an ad, the lead's contact information will also include a GCLID.

Once a week, your salespeople review that week's sales and send you the prospects (and associated GCLIDs) that converted into customers, along with the date and time of each sale. You then compile that data into a five-column spreadsheet and upload it into your Google Ads account. Within a few hours you'll be able to see which keywords and queries are contributing not just to new lead submissions, but, more importantly, to actual sales.

This new data saves you time and makes it easier to maximize your investment in Google Ads.

Conversions from calls

By importing call conversion information into Google Ads, you can track which of your ads and keywords result in the most sales calls for your business.

Instead of using a click ID as with conversions from clicks, you track information about your phone calls that resulted in sales or other valuable customer actions. When you import this information into Google Ads, these conversions are matched with phone calls from your ads.

Use automated bidding with offline conversions

You can use Google Ads automated bid strategies to optimize for offline conversions. If you do, it's a good idea to do the following:

  • Import offline conversion data frequently. (Daily is best.)
  • Begin uploading conversions and then wait the length of your conversion window before you turn on automated bidding.
  • If you're tracking a combination of online and offline conversions, try the target ROAS bid strategy. With target ROAS, you can better optimize for online and offline conversions by assigning different values to different conversion actions, such as leads and offline sales.


Say you’re tracking leads through an online conversion action, and final sales through an offline conversion action. You can assign different values to each conversion action to reflect the value each has for your business: for example, the value of a lead is $10, and that of a sale is $500. This gives Google Ads more insight into your sales funnel. And the more insight Google Ads has into your sales funnel, the better it can optimize your bids for you.

Smart Bidding for store visits

Available to certain advertisers, store visit conversions allow you to track how your ad clicks and viewable impressions influence visits to your physical locations. Unlike other offline conversions, store visit conversions do not require offline imports and are immediately available for qualified advertisers. Store visits can also be used in Smart Bidding strategies for Search and Shopping campaigns. Learn more About Smart Bidding for store visits.

Security and privacy for website tracking

Google's security standards are strict. Only pages containing the Google conversion tag are tracked through this program. We use data encryption and secure servers.

Please ensure you're providing users with clear and comprehensive information about the data you collect on your websites, and getting consent for that collection where legally required.
