How Quora counts conversions

Overview

Quora's conversion measurement connects ad engagements on Quora with actions people take on your website or app. This article explains how Quora counts conversions, what conversion types are available, how attribution windows work, and how Quora matches ad engagements to on-site events.

This article covers conversions for ads served on Quora. Reporting is available in Quora Ads Manager (QAM).

What is a conversion?

A conversion is an action a person takes on your website or app that you have defined as valuable — for example, completing a purchase, signing up for an account, or adding an item to a cart. Conversions are reported in QAM in the Conversions column.

Quora counts a conversion when both of the following are true:

• A person engaged with your ad on Quora within your selected attribution window, and
• A conversion event matching the action you're tracking fires on your website or app and is received by Quora through one of our supported tracking methods.

Each conversion event is counted in QAM at the time it fires, not at the time of the ad engagement that led to it.

Conversion types

Quora supports the following standard conversion types. Each type can be tracked independently, and conversions are reported separately by type in QAM.

Conversion type	Definition
Search	A person performs a search on your website or app.
Add to cart	A person adds a product to a shopping cart.
Add to wishlist	A person adds a product to a wishlist.
Initiate checkout	A person begins the checkout process for a purchase.
Add payment info	A person submits payment information during checkout.
Purchase	A person completes a purchase transaction.
Lead	A person submits information indicating interest in your product or service (for example, a form submission).
Complete registration	A person completes account registration on your website or app.
Generic event	A custom conversion event defined by the advertiser.

Conversion types fall broadly into two groups:

• Upper-funnel events (page view, view content, search, add to cart, add to wishlist) tend to fire more frequently per person and reflect engagement or interest.
• Lower-funnel events (initiate checkout, add payment info, purchase, lead, complete registration) tend to fire less frequently and reflect intent or completed action.

Per-event volume varies significantly by event type and by advertiser setup.

Attribution windows

An attribution window is the period of time during which a conversion can be credited to an ad engagement on Quora. If a conversion event fires after the attribution window has elapsed, it is not credited to that engagement.

Quora supports both click-through and view-through attribution windows:

Window type	Definition
Click-through (CTC)	The conversion is credited if it occurs within the specified window after a person clicked your ad.
View-through (VTC)	The conversion is credited if it occurs within the specified window after a person viewed your ad (without clicking).

The default attribution windows for oCPM campaigns are configured at the ad set level. Click-through attribution is generally treated as a stronger intent signal than view-through attribution.

If a person both clicks and views ads in your campaign before converting, the conversion is credited to the most recent qualifying engagement, with click-through taking precedence over view-through.

How Quora matches ad engagements to conversions

For Quora to count a conversion, the platform must connect the on-site or in-app conversion event back to an ad engagement on Quora. This is called matching.

Quora supports two methods of receiving conversion events:

Conversions API (CAPI)

The Conversions API sends conversion events directly from your server to Quora. CAPI is the recommended integration because it is not affected by browser-side limitations (such as ad blockers, browser privacy features, or cookie restrictions) and provides the most complete and reliable signal.

For more information about Conversion API, read our CAPI Overview.

Quora Pixel

The Quora Pixel is a JavaScript snippet placed on your website that sends conversion events from the browser to Quora. Pixel-based tracking is widely used and supports most standard conversion types.

A Quora Click ID (QCLID) is a parameter appended to URLs when a person clicks a Quora ad. When the QCLID is preserved and passed back with a conversion event — through the Pixel or CAPI — it provides a strong deterministic match between the ad engagement and the conversion.

For more information about the Quora Pixel, read our Quora Pixel Overview.

Matching priority

Quora uses the following order when matching a conversion event to an ad engagement:

1. Quora Click ID (QCLID) — when present, used as the primary deterministic match.
2. First-party identifiers — such as hashed email or hashed phone number, when shared via CAPI.
3. Cookie or device identifiers — for browser-based events received via the Pixel.
4. Probabilistic signals — IP address and user-agent. Used when none of the deterministic signals above are available. See Modeled conversions below for details.

When multiple matching signals are available for the same event, Quora uses the strongest available signal and counts the conversion once.

Deduplication

If the same conversion event is received by Quora multiple times — for example, from both the Pixel and CAPI for the same on-site action — Quora deduplicates the events when a shared event_id is provided.

Passing a unique event_id with each conversion event is the recommended way to ensure conversions are counted accurately when both the Pixel and CAPI are in use. Without event_id, Quora may not be able to deduplicate Pixel and CAPI events for the same on-site action, and the conversion may be counted more than once or counted less reliably depending on the setup.

How conversions are reported

Conversions are reported in QAM in the Conversions column. Conversions can be broken down by:

• Conversion type (purchase, lead, page view, etc.)
• Attribution type (click-through or view-through)
• Campaign, ad set, and ad level

CPA (cost per action) is calculated as spend divided by attributed conversions for the selected breakdown.

What's not counted

Quora does not count a conversion in the following cases:

• The conversion event fires outside the attribution window.
• The conversion event cannot be matched to an ad engagement on Quora using any of the matching signals listed above.
• The conversion event is a duplicate of an event already counted (when event_id is provided).

Conversions that fire on your site but cannot be matched to a Quora ad engagement using any of the signals above are not reflected in the Conversions column. Cross-referencing QAM reporting with your own analytics will show some differences for this reason — different platforms use different attribution methodologies and matching signals.

Modeled conversions

The Conversions column in QAM includes both deterministically attributed conversions and conversions attributed through probabilistic matching, sometimes referred to as modeled conversions.

Quora uses deterministic signals (QCLID, hashed first-party identifiers, cookies) wherever they're available. When none of those signals can connect an ad engagement to an on-site conversion event, Quora can attribute the conversion using probabilistic signals — specifically IP address and user-agent. This recovers conversions in cases where the deterministic signals needed for a direct match aren't present.

How we validate probabilistic matches. We confirmed the methodology by checking how matched conversions are distributed geographically. We use privacy conscious device and network signals, like IP address and User Agents, to improve match rates where permitted. 

How probabilistic and deterministic matches relate. Probabilistic matching is used as a fallback, not in parallel with deterministic matching. If a deterministic match is available for an event, that's used and the event is counted once. Probabilistic attribution only applies to conversion events that couldn't be matched any other way.

Reporting. Modeled conversions are included in the Conversions column alongside deterministically matched conversions. There is no separate column or toggle to view them independently. Bidding setup and billing are not affected by the inclusion of modeled conversions.

Per-advertiser impact varies based on tracking setup and audience.

Best practices

• Use both Pixel and CAPI with a shared event_id for the most complete and accurate conversion signal.
• Preserve the QCLID parameter on your landing pages and pass it back with conversion events when possible.
• Define conversion events explicitly rather than relying on default event names from third-party platforms.
• Compare equivalent attribution windows when reconciling Quora reporting with other platforms.
