Power words crank up your marketing effectiveness by: 1. Invoking emotion: People connect to emotion, not words. Studies show that content that elicits “high arousal emotion” (anxiety, amusement) is more likely to be shared and go viral than content that doesn’t elicit emotion or elicits “low arousal” emotion. Power words are key to evoking these “high arousal” emotions. Examples include words like “Instantly”, “Mistakes,” and “Hilarious”. 2. Triggering curiosity: Curiosity may have killed the cat, but it makes the marketer’s life easy. Research published by Harvard Business Review found curiosity to be one of the most powerful triggers for virality. Since we have a hard time resisting our curiosity, strategic use of power words makes it almost impossible for us to not to click, share, and read. Power words that trigger curiosity include words such as “Reveals”, “Proves”, “Ridiculous”. Here are 355 examples, where to use them, and how to combine power words for more sales, signups, and conversions.
