Secret sauces are the things that make your marketing stand out from the crowd. They are the things that make your marketing unique and special. Of course, if we list these out, they will not be unique. Use your imagination and think of things that will make your business or idea appear different to others.
Design and use your logo, everywhere. Make your logo into a work of art, it must be recognisible, simple, and unique. A logo that that creates a question in the mind could attract attention, but do not confuse your audience with mystery or too much "design". Your logo must communicate first and be easily imprinted on the memory. Your logo does not have to contain words, but it may, or indeed, it can have a companion caption.
Make your logo a part of your brand along with colour and font styles that suit your work. Use your logo on everything you do. Make your logo in more than one aspect ratio so you can use it with versility. For a website, 200px x 60px (wide) may work, for a business card, 60px x 60px (square) may work, depending on your design. Look different. Be different. Be unique.
