The CNMC tightens the screws on advertising influencers

Published on June 06, 2026 | Translated from Spanish

The National Commission on Markets and Competition has focused on influencers who promote products without properly labeling their advertisements. This action aims to help the public distinguish between organic content and paid advertising. Several content creators have received requests to adjust their practices, under threat of financial penalties.

How to implement clear labels in your affiliate campaigns 🏷️

To avoid legal issues, platform developers and influencers themselves must integrate visible labeling systems. Tools such as overlaid text labels, audio cues, or metadata in videos help comply with regulations. It is advisable to use terms like advertisement, paid collaboration, or sponsored at the beginning of the content. Transparency not only prevents fines but also improves audience trust.

The day the algorithm stopped being your secret ally 🤫

It turns out that putting #ad in the description, in microscopic font size and white color on a white background, no longer works. The CNMC has decided that fine print is no longer an excuse. Now it's time to be honest: if you get paid to sell miracle creams or trading courses, at least tell your followers before they report you from their couch. Transparency is cool, even if it stings a little in the pocket.
