Power Words for Sales: Boost Conversions with Persuasive Language

Have you ever bought a product that was recommended by experts? What about limited-time offers; special deals; premium packages? Have you ever bought a product sold under any of these labels? 

If you’re like most people, the answer’s “yes”. 

Here’s what you may not realize. All these offers use power words: an old, proven concept in both sales and marketing. These words, when used at the right time, persuade; build trust; overcome objections. 

In the past, power words were mostly used by marketers. But today, with the rise of remote sales - 3 in 4 buyers now prefer to make decisions online - they are increasingly used by salespeople. 

That’s because selling online gives you a lot more opportunities to use power words strategically. Email body text; asynchronous videos and video landing pages; pre-written video scripts. Assets like these make it easy to use power words the right way. 

And today, we’re help to help you do just that. Read on to find 100 of our favorite power words to improve your sales today. We’ll also give you the science behind power words to help you understand how they work. 

But first, let’s go over key takeaways! 

Key Takeaways

  • Power words evoke emotions and emphasize your offer’s value. They can help close deals and retain customers. 
  • Enriching your vocabulary with power words can improve sales performance. Scripts and content with power words tends to perform better. 
  • Using power words in subject lines, on-screen captions, and spoken text can help drive more business. 
  • Use the power words on this page to enrich scripts and content - including scripts made with our free Video Script Generator

The Science Behind Power Words

Emotionally charged words can capture a customer's attention and influence their actions. These power words are not just a gimmick; they’re rooted in cognitive neuroscience and psychological research. For example…

  1. Studies have shown that specific words can light up the amygdala, the emotional center of the brain. Using power words can elicit a specific emotional response that helps you sell your product.
  2. A study by Ellen Langer found that simply using the word “because” got people to comply with requests more often. This worked even when there was no real explanation for a request. 
  3. Incorporating words like "exclusive," "limited," and "guaranteed" into copy consistently increases conversion rates

That being said, it’s ultimately what you say; how you say it is important but secondary. Exaggeration or misrepresentation can backfire, causing distrust. Even the best power words can’t overcome weak marketing or sales processes.
