1- Focal Point: It should be the focal point of your design. You should plan well whether you will attract the attention of your target audience with your price, product or campaign call and place this important part in the focus of your design.
2- Typography: If you are designing for a sports brand, it will be wrong to use handdrawn fonts, you can choose stronger and italic fonts, or if you are a baby-child brand, you should choose softer fonts.
3- Colors: If you want to create assertive campaigns, contrasting colors may attract the attention of more consumers, but if you want to make harmonious collection presentations, it may be more beneficial to use color palettes that support each other. You can benefit from websites such as coolors.co related to the use of color palettes.
4- Relevance: Your design may not always be up-to-date, but it can be. You should support it with the most popular emojis, use the most popular fonts and include the most popular effects.
5- Understandability: While making a design, try to produce creatives that the consumer can make sense of in 2 seconds and read your call to action.
