I don't know the rules of grammar. If you're trying to persuade people to do something, or buy something, it seems to me you should use their language.
David MacKenzie Ogilvy (June 23, 1911July 21, 1999) has been often called 'The Father of Advertising'. In 1975, Time called him the most sought-after wizard in the advertising industry. In early 2004, Adweek magazine asked people in the business Which individuals alive or dead made you consider pursuing a career in advertising? Ogilvy topped the list. And the same result came when students of advertising were surveyed. His best-selling book 'Confessions of an Advertising Man' is one of the most popular and famous books on advertising.
