DSP View-Through Conversions
Track view-through conversions for DSP campaigns with the Ours Privacy impression pixel, matching conversions back to ad impressions the viewer never clicked.
A view-through conversion is a conversion by someone who saw your ad and never clicked it. For display, programmatic, CTV, and audio campaigns that is most of the effect: the ad does its work in the impression, and the conversion arrives later through search, direct, or email. Measure clicks only and those campaigns look like they do nothing.
Ours Privacy measures view-through conversions with a 1x1 impression pixel served alongside your creative. Use this page to understand the methodology and which DSP destinations it applies to.
How View-Through Attribution Works
- The impression is recorded. Your DSP serves the creative with the Ours Privacy impression pixel in it. The pixel fires on render and records the impression, along with any campaign parameters or click and auction IDs passed in the pixel URL.
- The conversion is matched. When a conversion arrives, Ours Privacy uses the identity signals and matching options supported by your destination to look for an earlier impression.
- The DSP determines attribution. Available identifiers accompany the conversion so your DSP can apply its attribution rules.
Two properties of this setup are worth calling out, because they are what make view-through measurement hold up as browsers tighten:
- Served from your own domain. Use a custom domain to serve the impression pixel from your subdomain.
- Server-side dispatch. Conversions reach the DSP through Ours Privacy servers, so conversion delivery does not require the ad platform's browser script. The fields sent, including Client IP where supported, follow your destination mappings and governance settings.
Identity is what decides your view-through match rate. A view-through window is often days or weeks long, so the impression and the conversion are rarely in the same session. Whether they connect depends entirely on identity resolution. Read Visitor Identity and Matching before tuning anything else.
Click IDs and Auction IDs
DSPs split into two groups, and the difference determines how much you configure.
- Platforms that attribute on their own identity signals. The Trade Desk can match conversions using a device advertising ID or raw UID2 when enabled. Your destination mappings determine which signals it receives.
- Platforms that attribute on an ID you pass back. Basis uses a click ID; Viant takes a click ID or an impression ID, and The Trade Desk also accepts an impression ID. Capture the required ID with your impression pixel so it can accompany a later conversion.
Your DSP account team will tell you which model your account is set up for. The impression pixel page covers how to pass parameters and the exact pixel URL format.
DSP Destinations Documented for View-Through
These are the destinations where view-through measurement is documented end to end. Follow the same methodology on each: place the pixel in the creative, then configure the destination.
| Destination | Attribution signal |
|---|---|
| The Trade Desk | Impression ID, device advertising ID, or UID2 |
| Basis | Basis click ID |
| Viant | Viant click ID or impression ID |
| StackAdapt | Universal Pixel, with a StackAdapt click ID when present |
Viant and The Trade Desk also support matching conversions to earlier impressions by IP. An IP match associates network activity; it does not establish that the same person viewed the ad and converted. Follow each destination's setup instructions before enabling it.
Other DSP destinations. The impression pixel is a source, so you can serve it alongside any creative and the impression is recorded either way. But whether a given DSP credits a conversion as view-through depends on that platform's own attribution model and on having a signal it can tie to an impression. Several of our DSP destinations send hashed identity fields with no impression or click ID, which means view-through credit is entirely the platform's decision and we can't claim it end to end. If view-through is the point of your campaign, confirm the model with your DSP account team before relying on it, or contact support@oursprivacy.com and we'll check the specific destination with you.
Note: The view-through window itself, and how each platform reconciles view-through against click-through credit, is always set on the DSP side. Ours Privacy supplies the impression record, the identity resolution that connects it to a conversion, and the server-side dispatch.
Setting It Up
- Configure a custom domain to serve the impression pixel from your subdomain.
- Add the Pixel source and configure the impression event and its properties.
- Place the pixel in your creative in the DSP, so it fires on impression rather than only on click.
- Pass campaign parameters and any required click or auction ID in the pixel URL.
- Configure your DSP destination using its page above, then map your conversion events.
- Send
external_idoremailon your site so a viewer who converts on another device still resolves to the same person.
Next Steps
- Impression Pixel: the pixel URL format, parameters, and configuration.
- Visitor Identity and Matching: the identity resolution that decides your match rate.
- Conversion Attribution: multi-touch credit across every channel, including the touchpoints these impressions created.
- Custom Domains: serve the pixel first-party so its cookie is server-set and durable.
