What are 3rd Party Tags?

In the Taboola platform, “3rd Party Tags” are any externally-provided code designed to monitor, record, or track the performance of Taboola campaigns. More specifically, 3rd Party Tags are typically HTML tags (IMG pixels or Javascript tags) that are implemented by Taboola on a publisher’s page when your ad is displayed, seen, or clicked. These tags are used to transfer data to other platforms, outside of Taboola’s proprietary dashboard.

What can I do with these tags?

Ad Verification
Send live campaign data to your 3rd party tracking platform. Validate brand safety, numbers of impressions, viewable impressions and clicks.

Attribution
Observe the whole user journey, not just the last click. Measure the effectiveness of Taboola on users that have seen your ads (and have not necessarily clicked them).

Re-engagement
Identify users that have engaged with your Taboola ads and remarket them on other platforms. (Scroll to the end of this article to learn how to remarket your Taboola users in Facebook and Google Ads).

3rd Party Pixels - Notes (These notes are NOT relevant to JavaScript tags):

Allowed types:
image and text. No limitations on vendors.
We are limited in some ways by sites, apps, browsers or devices that are unable to execute pixel implementations. In such cases, even though the pixel data did not reach your 3rd party platform, your ad was indeed displayed.
For example, HTTP limitation in Chrome and Firefox latest versions will prevent tracking for http pixels.

3rd Party Tag Validation
We have several layers of validation when uploading 3rd party tags. We validate pixel URLs, ensuring that it matches URL conventions. If the URL you added does not match our validation, you will not be able to add it.

Possible Validation Errors

“Only image/text pixels are accepted.”
“Pixel URL contains an invalid character: <state illegal character>.”
This means the pixel URL holds a character that is not in URL standards.
“Pixel URL structure does not match standard URL conventions.”
Check that you entered the pixel URL correctly.
“An error occurred when testing the pixel URL (4xx error).”
This error might mean that your 3rd party vendor does not allow Taboola server to check the URL endpoint.
It can also mean that the pixel URL is marked as not safe.
"URL is unavailable (5xx error)."
This means there was a server error. This might be due to temporary connectivity problems or a 3rd party’s server being down, but this can also mean the URL is permanently not available.
Please try again at a later time, check the URL for mistakes, and talk to you 3rd party to understand why you're receiving a 5xx error.
“URL not valid.”
The pixel failed another validation that is not mentioned above. Please contact support@taboola.com.
