The primary placement for the logo is centered at the bottom. However, if that is not possible, you can choose the placement that best suits the specific material. If centering the logo is not practical, position the logo in either the bottom-left or bottom-right corner. Placing the logo in a corner is often necessary when another element, such as an advertising message, footer-copy or a similar text, is placed in the opposite corner.
For web banners and social media materials, the logo should be positioned where it fits best within the design.
For rollups and similar materials where the focus is on the upper section, position the logo in the top-left corner and align the text to the left.
If the logo does not stand out against a photograph, you can subtly darken or lighten the background beneath it to enhance visibility.
