Both enhanced conversions and offline conversion import exist to recover conversions Google Ads would otherwise miss, which makes them easy to confuse. They solve different problems, and picking the wrong one leaves real sales unattributed. Here is how they compare.

What each one solves

Enhanced conversions supplements an on-site conversion with hashed first-party data, so Google can match a web conversion to an account even when cookies fail. Offline conversion import handles a different gap entirely: a conversion that happens later and off-site, like a CRM deal, uploaded back to Google using the original click ID. One strengthens matching for online conversions; the other brings offline outcomes into the picture.

Point by point

The differences are about where and when the conversion happens:

  • Where the conversion occurs – enhanced conversions: on your website; offline import: off-site, later, in your CRM or by phone.
  • What it matches on – enhanced conversions: hashed first-party data; offline import: the click ID (gclid) captured earlier.
  • Timing – enhanced conversions: at the moment of the on-site action; offline import: days or weeks later when the deal closes.
  • Main use case – enhanced conversions: ecommerce and on-site leads; offline import: long sales cycles and sales teams.

They are converging in 2026

The line between them is blurring, which adds to the confusion. Enhanced conversions for web and for leads are now a single setting, and enhanced conversions for leads itself matches offline lead outcomes on hashed data rather than only on the gclid. Meanwhile offline imports and leads uploads are moving to the Data Manager API as the old upload path closes in mid-2026. The tools increasingly overlap, but the underlying question of where your conversion happens still decides the right one. Do not let the shared setting fool you into thinking one switch covers both situations; the on-site match and the offline-value feedback are still distinct jobs under that single toggle.

When to use enhanced conversions

Reach for enhanced conversions when the conversion happens on your site and you have user-provided data at that moment, such as an ecommerce checkout or a lead form submission. It is the lower-effort option, often a setting plus tag configuration, and it directly lifts match rates for online conversions without any CRM work. For most website advertisers it is the first thing to turn on.

When to use offline conversion import

Reach for offline import when the outcome that matters happens after and away from the site, which is the reality for B2B and considered purchases. If a lead becomes revenue only once a salesperson closes it weeks later, that value lives in your CRM, and importing it is the only way Google learns which clicks produced actual customers rather than just form fills. Long sales cycles make this essential, not optional.

Most serious advertisers use both

These are complementary layers, not an either-or. Enhanced conversions sharpens on-site matching while offline import feeds back the downstream value, and together they give Google a complete view from click to closed deal. Especially for lead generation, running both is what lets the algorithm optimize toward revenue instead of toward cheap, low-quality form fills.

A simple rule for choosing

If you are unsure which a given conversion needs, one question settles it: where does the conversion actually happen? Follow that answer:

  • Happens on your website, with data at that moment (a checkout, a form): enhanced conversions.
  • Happens later and off-site, closed in a CRM or by a sales team: offline conversion import.
  • Starts on-site as a lead but only becomes revenue later: often both, with enhanced conversions for leads bridging the two.

Answering per conversion type, rather than picking one tool for the whole account, is what gets the most sales attributed, because a single business usually has conversions of more than one kind.

Enhanced conversions and offline import both recover conversions Google misses, but one strengthens on-site matching and the other brings in off-site, later outcomes. Choose by where and when the conversion actually happens, mind the 2026 move to the Data Manager API, and for long sales cycles run both. Do that and Google optimizes on the full journey from click to revenue, instead of only the part that happened on the page.
