(To those of you moaning about my ending a sentence with a preposition, I ask if you’d rather read Words With Which to Persuade. It truly is fine to stick a preposition at the end of your sentence if it sounds more natural.)
To persuade your audience, here is a list of words that will entice your readers to your side: you, yes, free, guarantee, easy, save, new, safety, benefits, discovery, health, now, sale, proven, money, results, love.
Please be sure when you use these words that you are not blowing smoke. If you are offering benefits, guarantees, or health, mean what you say. If you cannot back up your promises, you will lose all credibility.
