If you run Google Ads for a Shopify store, this one setting quietly shapes how many "conversions" your reports claim. It is also one of the reasons your Google Ads number and your Shopify order count never quite agree. Let's make it precise.
What the view-through conversion window actually is
A view-through conversion (VTC) is a sale credited to an ad that a shopper saw but did not click. Google records the impression, and if that person converts on your site within the window, Google claims the credit (Google Ads Help).
The view-through conversion window is how long that impression stays "credit-worthy." See the ad early Monday, buy late Monday — inside a 1-day window, Google counts it; buy Wednesday, it drops out.
This is a different setting from the click-through window, and mixing them up is the most common mistake merchants make.
Click-through vs. view-through: two windows, two defaults
Google Ads actually keeps two conversion windows on every conversion action, and they have different defaults (Google Ads Help):
| Window | What it counts | Default | Configurable range |
|---|---|---|---|
| Click-through | Conversion after a click on your ad | 30 days | 1 to 30, 60, or 90 days |
| View-through | Conversion after an impression (no click) | 1 day | 1 to 30 days (or 1 to 4 weeks) |
Source: Google Ads Help — About conversion windows.
So a display or YouTube impression only "counts" for one day by default, while a search click has a full month to convert. The view-through side is deliberately the tightest window Google offers out of the box.
Why the default is one day (and used to be thirty)
The one-day default is not an accident. Google shrank the AdWords view-through default from 30 days to 1 day on March 29, 2017 (Search Engine Land).
The reasoning: a view-through conversion is far weaker evidence than a click. Someone who merely saw a banner and bought three weeks later probably wasn't driven by that banner. Google's own framing was that view-through conversions are most credible when the message is still "fresh" — within a day (Search Engine Land). The change applied to both new conversion actions and existing ones still on the default.
The practical upshot: the default is conservative on purpose. If you widen it, you are choosing to claim more credit — not discovering hidden sales.
Worked example: what the 1-day window does to your reported numbers
Say you sell a $32 print-on-demand hoodie and you run Performance Max plus a YouTube campaign for a week. In that week, 100 real orders come in. Suppose the impression and click reality breaks down like this:
- 40 shoppers clicked a Search or Shopping ad, then bought within a few days.
- 25 shoppers only saw a display or YouTube ad — no click — and bought within 24 hours.
- 12 shoppers saw an ad but didn't buy until day 3 or later.
- 23 came from email, organic, or direct.
On the default 1-day view-through window, Google counts the 40 click conversions plus the 25 same-day view-through conversions = 65 attributed conversions. The 12 later view-through buyers fall outside the one-day window and are not credited to the impression.
Now widen the view-through window to 30 days. Those 12 slower buyers snap back into the count: 40 + 25 + 12 = 77 attributed conversions. Same 100 real orders, same ad spend, but your reported conversions jumped 12 units — 77 ÷ 65 = 1.18× — purely from a settings change.
Nothing about your business improved. You just told Google to reach further back and claim impressions it previously let go. That is the entire risk of touching this setting without understanding it.
Why your Google Ads and Shopify numbers still won't match
Even on the conservative 1-day default, Google Ads and Shopify count different things:
- Shopify has no concept of a view. It records a completed checkout and, by default, credits the last non-direct click. A view-through buyer clicked nothing, so Shopify files that order under the shopper's actual last referrer — email, organic, or direct — not Google.
- Google reports on the interaction date, not the purchase date. An impression Monday that converts Monday night lands on Monday in Google Ads; Shopify stamps the order when it happened.
- Cross-device. Google can tie a logged-in user's phone impression to a laptop purchase. Shopify sees only the buying session.
So even 65 tidy Google conversions won't line up with any single row in Shopify. This is the same structural gap merchants hit on Meta — where the default is a wider 7-day click + 1-day view window (Jon Loomer) — and it's why our guide to why Facebook Ads conversions don't match Shopify applies almost line-for-line to Google.

The profit angle nobody in the SERP mentions
Here's what the "how to change your window" articles skip: the window changes your reported ROAS, not your bank balance.
Widen the view-through window and your conversion count rises, so your ROAS — conversions (or conversion value) divided by spend — rises with it. Your Shopify orders and your Shopify payout do not move. You've made the campaign look more profitable without earning an extra dollar.
Walk it through. Say that week you spent $400 on Google Ads and those 100 orders each net you $9 in true per-order profit after product cost, print fees, shipping, and payment processing — that's $900 in real profit. Your profit on ad spend (POAS) against that campaign is $900 ÷ $400 = 2.25×. That number is the same whether Google reports 65 conversions or 77. The window is a reporting dial; profit is arithmetic on cash.
This is exactly where platform-reported numbers get dangerous. If you scale budget on an inflated view-through-heavy conversion count, you can grow "conversions" while shrinking actual margin. The same trap shows up when Facebook Ads revenue doesn't match Shopify and when GA4 ROAS doesn't match Shopify — three tools, three ROAS figures, one real profit.
Where PodVector fits
The point of getting the window right is to stop trusting any single platform's self-scored number and start deciding on profit.
That's what PodVector is for. It connects Shopify, Meta Ads, Google Ads, Printify, Printful, and Stripe, then computes your true per-order profit — product cost, fees, shipping, and ad spend netted against real Shopify orders, not against Google's view-through-inflated conversion count. Victor, its AI operator, reads that ad data and proposes moves; he does not touch your Google Ads account, and any action he takes on the Shopify side runs only with your approval. Victor is not a dashboard — he analyzes the numbers and acts on them.
So you can leave the view-through window on its conservative default, understand exactly what it's claiming, and still judge every campaign on the one figure that hits your bank: profit.
FAQs
What is the Google Ads default view-through conversion window?
One day. If you create a conversion action and don't change the setting, Google credits a view-through conversion only when a shopper sees your ad (with no click) and converts within 24 hours (Google Ads Help).
Can I change the default view-through conversion window?
Yes, per conversion action. You can set the view-through window anywhere from 1 to 30 days (or 1 to 4 weeks) when you create or edit a conversion action (Google Ads Help). Widening it increases the view-through conversions Google records, but it does not create new sales.
Is the view-through window the same as the click-through window?
No. They're two separate settings on the same conversion action. The click-through window defaults to 30 days and can go up to 90; the view-through window defaults to 1 day (Google Ads Help). Click evidence is stronger, so Google gives it a longer default lookback.
Why did Google change the default from 30 days to 1 day?
Google shrank the AdWords view-through default from 30 days to 1 day on March 29, 2017, on the logic that an impression is most credible when it's fresh — within a day (Search Engine Land). A view three weeks before a purchase rarely caused that purchase.
Should I widen my view-through window to get more conversions?
Be careful. Widening the window inflates your reported conversion count and ROAS without changing your Shopify orders or your payout. If you optimize toward that inflated number, you can scale spend while margin shrinks. Judge campaigns on true per-order profit, and keep the window narrow unless you have a specific measurement reason to widen it.
Why does Google Ads report more conversions than Shopify shows orders?
Because Google counts view-through impressions and reports on the interaction date, while Shopify records only completed checkouts and credits the last non-direct click. A view-through buyer clicked nothing, so Shopify never files that order under Google. The two systems answer different questions and are not meant to match — the same reason GA4 ROAS doesn't match Shopify.
