A JSON advertising system includes an ad management system, a bot builder module, a social network platform, a bot platform, and a client, all mutually connected via a suitable network. An advertiser stores an ad creative into an ad server located in the ad management system, and generates JSON code via a JSON code tool within the bot builder module for each part of advertisement content stored in the ad server. Then, a client logs into a social network platform news feed, retrieving and displaying the advertisement. A user engages the ad and is redirected to a bot platform chat interface, retrieving bot advertisement content from a bot server and linking the content to the advertisement stored in the ad server as determined by the JSON code.
