A system and method are disclosed that enable user-customized 3D ad model placement in augmented reality videos. The first part of the algorithm involves adding markers into the video created by the video providers. The system for broadcasting the video includes an algorithm to predict the products the user is likely to purchase, thus customizing advertisement placement. A 3D model is generated for the product identified by the prediction algorithm. The system combines the product generated via the prediction program with the markers on the video to generate the placement. Thus a video is displayed on the user’s device with an ad for the product customized for the user. This enables the user to click on the product for information or purchase and increases the chances of the user purchasing the product. The disclosed method of model placement has high reliability, user specificity and cost effectiveness in advertising
