Hidden advertising

A paid partnership presented as a personal recommendation or independent opinion, without a clear “ad” label.

We treat recommendations from people we follow almost like advice from a friend. If money, a free product or a commission from a discount code is behind them and nobody says so, it is advertising in disguise – and under EU rules it has to be clearly labelled.

Example · made up for illustration
A video on a parenting account: “We finally sleep! This night light changed our nights. Use my code BARA15 for 15% off – valid until midnight only.” Nowhere does it say the creator got the lamp for free and earns a commission on every sale.

How to spot it

  • A discount code or a “link in bio” without the word ad – it usually earns the creator a commission.
  • “This arrived in the post” or “we were sent this to try”, but no label for the partnership.
  • An “independent comparison” in which the winner has the only shopping link.
  • The label is hidden at the end among hashtags or behind “more”.

How to check and what to do

  • Look right at the start for the word “ad”, “paid partnership” or the partnership label offered by the platform.
  • Ask: What does the creator get from this – money, a product, a commission?
  • Compare the price and reviews outside the post, in shops and from people who bought the item.

Tip: A labelled ad is fair. But it is still an ad – think the purchase over as you would with a flyer.

The card fits on one A4 page – for the classroom, a noticeboard, or parents and grandparents.
