General Guidelines
Text Size
There is a minimum text size requirement for Criteo banners, which is 10px on desktop and IAB versions, and 30px on mobile versions. We set up this rule for accessibility reasons, in order to make all our formats legible for everyone.
Contrast
Be careful with the contrast of the colors of texts and UI elements in your creatives. Still, for accessibility reasons, we do not accept texts or buttons with a color that makes them difficult to read. You can check the contrast ratio of your colors on the web. The minimum good ratio according to the Web Content Accessibility Guidelines is 4,5:1.
Background Color
For the background, we don’t recommend using flat white color since when the banners are live on the retailer’s website, the color of the product grid (which we can find on the side of the banner) and the website background is white too. So, in order to differentiate the banner and make it stand out from the background of the retailer’s website, we should preferably use other colors.
