Click-Through Conversion
A click-through conversion (CTC) occurs when a customer clicks on an ad and then completes a purchase within the attribution window.
What Is a Click-Through Conversion?
A click-through conversion happens when a customer clicks on your ad and subsequently makes a purchase within the attribution window. Unlike view-through conversions, which count passive ad impressions, click-through conversions require an active interaction: the customer deliberately clicked your ad.
This is the most widely trusted conversion type because there is a clear, direct link between the ad and the customer action.
How Click-Through Conversions Work
The tracking flow is straightforward:
- Your ad appears on Meta, Google, TikTok, or another platform
- The customer clicks the ad and lands on your Shopify store
- The click is recorded by the ad platform (via a cookie, click ID, or UTM parameter)
- The customer completes a purchase (immediately or within the attribution window)
- The ad platform matches the purchase back to the original click
Click-Through vs View-Through
The distinction between these two conversion types significantly affects your reported numbers:
| Click-Through | View-Through | |
|---|---|---|
| Customer action | Clicked the ad | Only saw the ad |
| Confidence level | High | Low |
| Platform default | Always included | Often included by default |
| Inflation risk | Low | High |
| UTM trackable | Yes | No |
Most experienced Shopify merchants focus on click-through conversions for decision-making and treat view-through conversions as supplementary data.
Why Click-Through Conversions Still Get Inflated
Even click-through conversions are not perfectly accurate. There are several ways the numbers can be overstated:
Multi-platform double counting
A customer clicks a Facebook ad on Monday and a Google ad on Wednesday, then buys on Wednesday. Both Facebook (7-day click window) and Google (30-day click window) claim the same conversion.
Long attribution windows
With a 28-day click window, a customer who clicked your ad a month ago and then returned through organic search gets counted as an ad conversion. The longer the window, the more organic purchases get attributed to ads.
Accidental clicks
On mobile, accidental ad clicks are common, especially with interstitial and video ads. The customer clicks unintentionally, bounces immediately, and returns later on their own, but the click is still on record.
How to Get Accurate Click-Through Data
The most reliable way to track click-through conversions on Shopify is through UTM parameters. When a customer clicks your ad and arrives with UTM tags, you have first-party proof that the click happened. This data lives in your own system and is not affected by:
- Platform-specific attribution logic
- Cross-platform double counting
- iOS privacy restrictions (the UTM is captured on your site)
Click-Through Conversions in Detectly
Detectly tracks click-through conversions by capturing UTM parameters from every ad click and tying them to Shopify orders. Because this is first-party, server-side data, it is not subject to the inflation, double-counting, or privacy gaps that affect platform-reported click-through numbers. Your dashboard shows true click-attributed revenue by source, medium, and campaign.
