Through CTR's own EMOOB model, we sort out the current marketing budget share structure and allocation basis of advertisers/merchants for Internet platforms; understand the advertisers'/merchants' evaluation of the platform's current products, services, etc.; monitor the performance of various brand health indicators of advertisers'/merchants' confidence and willingness to cooperate with the platform in the medium and long term, thereby helping Internet platforms to achieve traffic monetization and win-win situations with advertisers/merchants in supply relationships.
