Try not to draw attention to yourself - this is a very good strategy in many situations in life. In advertising, however, the exact opposite is true. So take a look at what your competitors are doing - and then do something different yourself. By doing this, you can demonstrate that your company is something special. This will mean that you are remembered and that, after all, is what advertising is about.
However, it is also important to stay true to yourself. Give your customers a waterproof shower radio as a gift. Hand out ceramic business cards. Cover a company van with a mosaic. I.e. create advertising which stands out because it is especially suited to your company.
