Offline Conversion Import

In one lineFeed offline sales back so bidding chases revenue.

Offline Conversion Import feeds sales that close away from your site, a phone call, a CRM deal, an in-store purchase, back into Google Ads so Smart Bidding can optimize toward real revenue rather than just form fills.

You generate leads online, but the money shows up later and somewhere else, when a rep closes the deal or a customer walks into your shop. Google Ads never sees that outcome on its own, so it optimizes toward the cheapest form submission instead of the leads that actually pay. Offline Conversion Import closes that loop by sending the real result back to the account.

Once Google knows which clicks turned into revenue, it stops treating every form fill as equal and starts favoring the traffic that produces closed business. There are two current ways to connect it. The older method captures the Google Click ID (GCLID) on each lead and reimports it when the sale closes. The newer, recommended method is enhanced conversions for leads, which matches on hashed customer data like an email address instead of a stored click ID.

Be realistic about the cost. It requires capturing that click identifier or setting up enhanced conversions for leads, and the outcome data arrives with a delay because deals take time to close. Even so, for a lead-gen business this is often the single highest-value measurement upgrade you can make, because it teaches the system what a real sale looks like instead of what a cheap lead looks like.

Teach the algorithm what a real sale looks like, and it will go find you more of them.
