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 optimise your campaigns for increased profit.

If you attract either leads or buyers (or both) online, then 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 an online sale so that you can exclude those transactions that resulted in a return
  • Only when a sale has been made to a new customer
  • Only if it's a customer's second purchase
  • When you close a sale online but are unable to use our standard JavaScript-based conversion tracking solution

How it works

Offline conversion imports 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 using GCLID

Google Ads provides you with a unique ID, called Google Click ID (GCLID), for every click that comes to your website from an ad. To track offline conversions from clicks, 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 that 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 are converted into customers, along with the date and time of each sale. You then put 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 maximise on your investment in Google Ads.

Conversions from clicks using enhanced conversions for leads

Enhanced conversions for leads allows you to upload offline conversion data using first-party customer data. This method is easier than using conversion from clicks using Google Click ID since it doesn’t require you to modify your lead forms or customer relations management (CRM) systems to receive a Google Click ID (GCLID). Instead, it uses information that was already captured in your lead forms to measure conversions.

Once you’re ready, you can set up enhanced conversions for leads.

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 the 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.

For more information about how this option works, read about importing phone call conversions.

Use automated bidding with offline conversion imports

You can use Google Ads automated bid strategies to optimise 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 optimise for online and offline conversions by assigning different values to different conversion actions, such as leads and offline sales. Before adopting target ROAS, we recommend that you include the new values in the ‘Conversions’ column and wait six weeks for your campaign to receive conversion values at a similar rate. We also recommend reviewing your budget settings to make sure you feel comfortable spending up to two times your average daily budget, while not exceeding the monthly charging limit.


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 that 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 optimise your bids for you.

Security and privacy for app tracking

Google's security standards are strict. Google Ads only collects data on apps where you have configured tracking.

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