Attorneys handling evidence disputes retain a social media expert to authenticate and explain platform records — here's how that works →

A Facebook expert witness provides courts with specialized knowledge about how Facebook works — including algorithmic distribution, advertising mechanics, engagement metrics, content authentication, and platform-native data analysis. Expert testimony is used in defamation, employment, IP, and personal injury matters.
Facebook's algorithm determines what content users see based on engagement signals, account relationships, and content type. Organic reach — the percentage of followers who actually see a post — has declined significantly over the past decade. Expert analysis is required to distinguish organic reach from paid amplification and to contextualize what any given reach figure actually means.
Yes, but authentication requires more than a screenshot. Platform-native data obtained through Meta's legal process, URL-verified captures with metadata, and expert testimony are required for reliable authentication. Facebook's editing, deletion, and privacy setting features create additional complexity.
As early as possible. Facebook content can be deleted and privacy settings changed after litigation begins. Early retention allows for proper preservation requests and ensures the most complete evidentiary record.
