US Patent 11516277 Script-based techniques for coordinating content selection across devices

Methods and systems are disclosed for coordinating content selection across devices. A user device may transmit a request for webpage content and in response, may receive response communications that include the webpage content, embedded content, and a script. The user device may retrieve a device identifier initially generated by a remote system from a locally stored data object. The user device can detect, using the script, whether at least part of the embedded content is being presented within a portion of the webpage that is displayed on a screen of the user device. The user device may then transmit a report communication to a remote ID-graph system that includes the device identifier and an indication as to whether the at least part of the embedded content was presented within the portion of the webpage that was displayed on the screen of the user device.
