If someone wants to become a designer of advertisements there are several key skills that they need to have. Campaign managers will look for these when choosing the right candidate. It can take years of experience and education to master the art of design.
First and foremost the person should have a good eye for what the general public finds visually appealing. Anyone starting out in the industry should research the most successful marketing examples and analyse their aesthetics. It is a good idea to learn the ins and outs of colour theory in particular. The website BBC features plenty of information on this subject. Understanding it will prevent designers from combining hues that clash.
When given a project the person has to work to a set deadline. Consequently, marketing designers should be adept at time management. If the final product is not handed in on time the client will likely seek someone else for the next one.
Even though modern design is mainly digital the person will still interact with people. Therefore, confidence when faced with social situations is another key skill to have. Throughout the work day employees will talk to their colleagues, managers and clients.
