The code you've provided appears to be part of a larger script commonly used for rendering digital advertisements, tracking user interactions, and collecting analytics. Here's an explanation of what the code is doing:
-
URL Parameter Parsing and Referrer Checking:
- The script extracts and processes the
document.referrer
(the URL of the webpage where the user came from before visiting the current page). - It checks if the referrer domain is different from the current webpage's domain (
location.host
). If so, specific parameters likeft_ifb
andft_domain
are added for reporting purposes, likely indicating the cross-origin nature of the page load.
- The script extracts and processes the

Ad Configuration (
ftV_9088785
):- An object (
ftV_9088785
) is defined with a set of parameters configuring an advertisement with specific attributes:pID
,width
,height
: Define the placement ID and ad dimensions (e.g., 320x50 pixels for a mobile banner ad).- Other properties (
params
) collect details about the ad's environment, such as the user's position (ftx
,fty
), custom IDs (ft_id
,ft_mcid
), GDPR compliance status, privacy flags, and various advertising-related identifiers. - This object likely serves as a configuration for the ad placement and interaction tracking.
- An object (

Utility Functions for Encoding/Generalization:
- Certain utility functions within the code handle tasks such as:
- Encoding URLs or strings for safe transmission (
l
function). - Serializing or deserializing objects.
- Encoding URLs or strings for safe transmission (
- This ensures data passed to or from the ad server is properly formatted and compatible.
- Certain utility functions within the code handle tasks such as:
-
Dynamic Script Injection:
- The script dynamically creates and injects a
<script>
tag (ftTag
) into the webpage's DOM.- The injected script is responsible for fetching and displaying the actual advertisement from the Flashtalking ad server (
https://servedby.flashtalking.com
).
- The injected script is responsible for fetching and displaying the actual advertisement from the Flashtalking ad server (
- The mechanism also includes a timeout (
GTimeout
) to ensure that the ad is deployed even if other scripts take too long to execute.
- The script dynamically creates and injects a
-
Ad Tracking and Callbacks:
- Various callback functions and tracking parameters are included to log impressions, clicks, and other ad activities.
- This is a standard feature in online advertising to measure the performance of an ad campaign, such as how often it was clicked or seen.
-
Fail-Safe Mechanism:
- A timer (
gTimer
) ensures that if the ad doesn't deploy within a certain period, a fallback mechanism triggers the deployment function (deployTag
).
- A timer (
Key Features of the Code:
- Serves as part of an ad-serving process, dynamically embedding an ad script.
- Tracks user interactions and environment (e.g., referrer, device type, keywords).
- Adapts to the page's context (like cross-origin environments) and passes detailed parameters to the ad server.
- Includes compliance flags like GDPR data consent and user privacy settings.
Purpose:
The script is typically used in online advertising to display advertisements (in this case, a 320x50 banner ad), track user interactions, and report related analytics back to the advertising platform (in this case, Flashtalking).
If this code is from your site, ensure it's compliant with privacy regulations like GDPR (if in the EU) and other global privacy standards, as it collects and processes browser and behavioral data.
