Overview
If you run a test conversion and discover that no conversions have been recorded, you can review the pixel log for potential errors and their corresponding solutions in this KB.
As you test, you will determine if the advertiser has accurately placed the pixel on the thank-you page of the website.
What is a pixel?
A pixel is usually a 1×1 invisible image or JavaScript snippet that fires when a user loads a page (most commonly a “thank you” or confirmation page).
When it fires, it sends information back to the tracking system (like Trackier) such as:
click ID
campaign ID
conversion event (lead, sale, install, etc.)
timestamp
device/browser data
What is this issue?
When a pixel is not recorded in Trackier, it means the conversion tracking request (pixel/iframe) is not successfully reaching or being processed to the Trackier system.
In simple terms:
The advertiser’s “thank you page” pixel is firing, but Trackier is not receiving or validating it correctly
Why does this happen?
Pixel tracking failures usually happen due to issues in placement, session mismatch, or incorrect parameters.
Common reasons include:
Pixel not placed correctly on the thank-you page
Click session not generated (user didn’t come via tracking link)
Invalid or missing click ID
Wrong campaign ID or goal configuration
Duplicate or repeated click ID usage
Parameter mismatch in pixel (goal value, order ID, etc.)
Errors and their possible solutions
Error | Possible Solution |
-- | It means success, and there is no error. You will see this conversion in the conversion logs as well. |
BLANK (there is nothing on the page) | It means no pixel is placed on the advertiser's end or is not in the <body> tag. |
NO_SESSION_ID | Users have not landed on the landing page from the tracking link; it might be an organic conversion. |
NO_CLICK_FOR_SESSION | It means no valid click is available against this pixel firing. |
DUPLICATE_CLICK_ID | It means conversion is already recorded with the same click id if it is a purchase-type campaign; then enable tracking multiple conversions from the same click id from the campaign setting. |
INVALID_CLICK_ID | It means the click ID doesn't belong to the Trackier platform, and it is not a genuine test with the Trackier tracking link. |
INVALID_CAMPAIGN_ID | It means a pixel from another campaign is placed on the advertiser's end; please check and share the pixel again. |
INVALID_GOAL_VALUE | The goal value created in the campaign does not match what we are getting in the fired pixel log. It is possible that while adding pixels, something got omitted from the goal value. You may either change the goal value in the campaign or get the goal value changed by your advertiser in the pixel placed. |
ORDER_DATE_IN_PAST | This error can arise because of two situations:
|
Steps to find if the Advertiser placed the pixel correctly
Step 1: Generate a Tracking link in the campaign (make sure the tracking link's domain matches the domain of iframe or image pixel that is placed on the website)
Step 2: Paste that tracking link in the browser and do not hit it directly.
Step 3: After that, right-click anywhere on the page and open Inspect.
Step 4: Select Network in the Inspect menu and check Preserve Log.
Step 5: Fill in the test lead on the page and submit.
Step 6: When the Thank You page appears, search “your tracking domain” in the INSPECT menu and try to find your Pixel.

Verifying the placement of pixel
If you find the pixel and it is fired, check the pixel log and conversion log.
Make sure your txn_id, sale_amount, and any other parameters that you have added in the pixel are getting replaced with a value.
If you don't find your pixel in the list, then the pixel is still not placed. Take a screenshot of the full page with developer mode on and share the same with the advertiser.
Once it is added by the advertiser, test it again with the tracker's tracking link.
When you have successfully recorded the conversion, you can go live with the campaign.
Note:
Trackier provides you with an option to reject the pixel if a particular required information is not received.
For example, if you want to reject the conversion or pixel if the transaction ID is missing then the system will automatically reject that conversion or fired pixel.
You can access this setting from the basic settings of your campaign:
You can apply these settings on Sale amount, Transaction ID, and all open parameters (Sub1 to Sub10)
Tips to avoid pixel issues
Always place pixel on final confirmation page
Never modify tracking URLs manually
Test using fresh browser session (not cached/incognito issues)
Ensure click ID is always dynamic
Validate logs after first live traffic
Conclusion
Pixel not recorded issues in Trackier usually come down to broken session flow, incorrect placement, or parameter mismatch.
In simple terms:
If the click ID flow between user → campaign → thank-you page is broken, the pixel will not be recorded.
Once placement, session tracking, and parameters are aligned correctly, pixel tracking becomes fully reliable.
