X introduces new advertising formats and paid partnership labels

X is implementing new features to streamline advertising and improve content transparency. The platform has expanded its supported image and video formats to allow advertisers to reuse creative assets designed for other social media networks, such as Instagram and TikTok, without manual resizing. New supported ratios include 4:5 and 2:3, alongside existing formats like 1:1 and 16:9.

Additionally, X has introduced an official ‘Paid Partnership’ label for creators. This tool allows users to clearly disclose commercial partnerships via a ‘content disclose’ option during or after posting, rather than relying on hashtags. Nikita Bier, head of product at X, stated that undisclosed promotions hurt product integrity and user trust. This move aligns with regulatory expectations, such as those from the U.S. Federal Trade Commission, regarding the clear disclosure of sponsored content.
