How EST Works
PhotonIQ Edge Side Tagging (EST) relocates the execution of resource-demanding third-party scripts, typically utilized for advertising, analytics, and tracking, from the user's browser to a server-side environment at the network edge. This strategic shift significantly improves web performance and bolsters data privacy by minimizing client-side processing.
By executing third-party scripts server-side, EST dramatically reduces the load on the end user’s browser. This not only speeds up the website but also enhances user privacy by limiting the amount of data processed client-side. Moreover, EST's architecture aligns with modern web standards, offering a robust solution for website owners seeking to optimize performance and comply with evolving privacy regulations

How It Works
The operation of EST involves a few key steps:
- Initial Configuration: - Configure your full domain address.
- Set cookies in PhotonIQ EST settings via the web console.
- Tailor third-party component behavior to your website's needs.
 
- Integration Script Embedding: - Embed the PhotonIQ EST integration script on your website.
- The script is lightweight, ensuring minimal impact on page load times.
 
- Cookie Management and Tracking: - The integration script activates PhotonIQ EST tracker APIs during page visits.
- These APIs generate specialized cookies for each third-party component, optimizing EST's tracking.
- The cookies balance user interaction tracking with performance and privacy.
 
- Event Generation and Processing: - User interactions on the site generate events.
- The tracker API captures these events and relays them to PhotonIQ EST.
- PhotonIQ EST processes events according to settings for each third-party component.
 
- Data Transmission to Third-Party Services: - Processed data is securely and efficiently sent to third-party services.
- Transmission complies with user settings, ensuring data handling meets website functionality and compliance standards.
