Never write an advertisement which you wouldn't want your family to read. You wouldn't tell lies to your own wife. Don't tell them to mine.
David OgilvyDonโt just create content to get credit for being clever โ create content that will be helpful, insightful, or interesting for your target audience.
David OgilvyMost headlines are set too big to be legible in the magazines or newspaper. Never approve a layout until you have seen it pasted into the magazine or newspaper for which it was destined. If you pin up the layouts on a bulletin board and appraise them from fifteen feet, you will produce posters.
