YMYLYMYL is the acronym for Votre vie ou votre argent.
Your Money or Your Life (YMYL) content is the type of information that, if presented inaccurately, untruthfully, or deceptively, could directly impact the reader’s happiness, health, safety, or financial stability.
In other words, the stakes are high for this type of content. If you create a YMYL page with bad advice or bad information, it could affect people’s lives and livelihoods.
Google takes this content very, very seriously. Experts with relevant expertise need to write YMYL content.
