# Conversion Tracking Methods Explained

> Understand the different ways to track conversions in ClickFlare and choose the right method for your setup

## Overview

ClickFlare supports multiple ways to register conversions. While they all achieve the same goal—recording a conversion and attributing it to the correct campaign—they differ in **reliability**, **requirements**, and **best-fit use cases**.

This article helps you answer a common question:

> **Which conversion tracking method should I use for my campaign?**

It compares each method at a high level and explains when to use one over another.

***

## The Five Conversion Tracking Methods in ClickFlare

ClickFlare can register conversions through the following methods:

1. **S2S Postback (Server-to-Server)**
2. **Conversion Tracking Pixel (Image Pixel)**
3. **Conversion Tracking Script (Thank-You Page Script)**
4. **API-Based Pull (Integration)**
5. **Manual Conversion Upload**

All methods rely on the same principle:
👉 **the conversion must be matched to a valid ClickFlare Click ID**.

***

## 1) S2S Postback (Recommended)

**Best for:** Most affiliate networks and paid traffic setups

### How it works (high level)

* ClickFlare passes a Click ID to the affiliate network
* When a conversion happens, the network sends that Click ID back to ClickFlare via a server-to-server request

### Why this is the preferred method

* Does not rely on the user’s browser
* Not affected by cookies, ad blockers, or page load issues
* Most accurate and reliable option

### Use S2S postback if:

* Your affiliate network supports postback URLs
* You want maximum tracking reliability
* You are running performance-driven campaigns

<Info>
  **Recommendation:**
  If S2S postback is available, always use it.

## 2) Conversion Tracking Pixel (Image Pixel)

**Best for:** Simple funnels where S2S postback is not available

### How it works

* ClickFlare stores the Click ID in the browser
* A hidden image pixel fires on the thank-you page
* The pixel sends a conversion request to ClickFlare

### Limitations

* Relies on browser cookies
* Can fail if cookies are blocked or cleared
* Less reliable than S2S postback

### Use a pixel if:

* You do not have access to postback tracking
* You control the thank-you page
* Occasional tracking loss is acceptable

***

## 3) Conversion Tracking Script (Thank-You Page Script)

**Best for:** Browser-based tracking with improved reliability

### How it works

* Similar to the image pixel
* Uses JavaScript instead of a static image
* Can read/set first-party cookies on the page domain

### Why it’s better than a pixel

* More resilient in some cross-domain scenarios
* Better cookie handling in modern browsers

### Use the script if:

* You control the thank-you page code
* You want a browser-based fallback that’s more reliable than an image pixel

📌 Still less reliable than S2S postback.

<Info>
  **Note**: Pixel- and script-based tracking fires on page load. If a user refreshes or revisits the thank-you page, the conversion request may fire again. While ClickFlare typically deduplicates conversions using the Click ID, setups that use dynamic transaction IDs (txid) can unintentionally overreport conversions.

  For this reason, pixel- and script-based tracking should be treated as a fallback method and used carefully. Whenever available, server-to-server (S2S) postback tracking is strongly recommended, as it fires conversions once, server-side, and is not affected by page reloads or browser behavior.

## 4) API-Based Pull (Integration)

**Best for:** Platforms where ClickFlare pulls conversions and revenue directly

### How it works

* ClickFlare connects to a supported platform via API
* Conversions and revenue are pulled automatically
* No postback or pixel is required

### Important clarification

This method works **only when a supported integration exists in ClickFlare**.

It is commonly used for:

* Certain affiliate networks
* Search monetization feeds
* Revenue streams with delayed reporting

### Use API-based pull if:

* A native ClickFlare integration exists
* The platform provides conversion data via API
* Revenue is delayed or finalized later

<Warning>
  **Do not confuse this with Conversion API integrations**, which are used to send conversions *from* ClickFlare *to* traffic sources.
</Warning>

***

## 5) Manual Conversion Upload

**Best for:** Edge cases and recovery scenarios

### How it works

* You manually upload conversions via the ClickFlare UI
* Each conversion must include a valid Click ID
* Optional payout, transaction ID, type, and timestamp can be included

### Typical use cases

* Offline conversions
* Missed postbacks
* Delayed reconciliation
* One-time corrections

📌 Manual upload is not intended for real-time tracking.

## Comparison Overview

| Method          | Reliability | Browser-Dependent | Recommended      |
| --------------- | ----------- | ----------------- | ---------------- |
| S2S Postback    | ⭐⭐⭐⭐⭐       | ❌ No              | ✅ Yes            |
| Tracking Script | ⭐⭐⭐         | ✅ Yes             | ⚠️ Fallback      |
| Image Pixel     | ⭐⭐          | ✅ Yes             | ⚠️ Fallback      |
| API Pull        | ⭐⭐⭐⭐        | ❌ No              | ✅ When available |
| Manual Upload   | ⭐           | ❌ No              | ❌ Exception only |

## Can You Use Multiple Methods at Once?

Technically yes, but **not recommended**.

Using more than one method for the same conversion can result in:

* Duplicate conversions
* Inflated revenue
* Reporting inconsistencies

📌 **Best practice:**
Use **one conversion tracking method per conversion event**.

***

## Common Mistakes When Choosing a Method

* Using pixel tracking when S2S postback is available
* Assuming Conversion API integrations report conversions *into* ClickFlare
* Mixing multiple methods for the same event
* Forgetting to pass the Click ID to the affiliate network

***

## How to Choose (Quick Decision Guide)

* **Affiliate network supports postback?** → Use **S2S postback**
* **No postback, but you control the thank-you page?** → Use **script**
* **No script access?** → Use **image pixel**
* **Using a supported revenue/feed integration?** → Use **API pull**
* **Need to recover missed conversions?** → Use **manual upload**
