Recognising Sponsored Content Markers
Launch library · evergreen read

Sponsored content is designed to resemble the surrounding editorial material closely enough that a quick reader might not notice the difference at all, while typically carrying a small disclosure label such as 'sponsored', 'partner content' or 'advertisement' somewhere near the headline or byline itself, though the exact wording and placement varies between publishers.
These labels exist because of disclosure requirements in many places, but they are genuinely easy to skim past, especially within a format matching the rest of a site's usual design so closely. Slowing down to check the label before treating an article as independent reporting avoids a common and entirely understandable mix up.
Sponsored content is not automatically dishonest in itself, but it is written specifically to promote something, which is a rather different purpose from independent reporting and worth reading with that underlying purpose kept clearly in mind throughout, rather than assumed to carry the same independence as the rest of the page.
