A computer-implemented system and method is provided herein for social commerce analytics and optimization. A hosted platform collects and stores online visitor traffic data from social media platforms and from commercial platforms linked to social media campaigns operating on the social media platforms. Algorithms are executed to establish baseline performance parameters for the commercial platforms based on the stored data, and visitors of the social media campaigns and commercial platforms are identified and scored based on predetermined scoring metrics. The scores are aggregated with respect to the social media campaigns and/or the commercial platforms, and actual performances based on the aggregated scores are compared with the established baseline performance parameters. An interface may be generated for a client user associated with the commercial platform to represent one or more of the performance comparisons, and optionally provide alerts to underperformance or suggest future actions based on predicted performance.
