Many of us have never write any Adds until we start working with SFI. But yet we all succeed with it!
You have to read others Adds, not to copy them, but to make something different, something original! All that people see is the Title! So, for example, use larger font for the words that you want to highlight - words that will attract more attention! Use colors and pictures!
Important is that your Add need to be short, simple, powerful, and original!
