Using triggers in your sales copy does help to increase your conversions.
Here are 4 effective triggers that you can use in your own sales letters.
1.
Intrigue Using words that build intrigue work well because as humans we have an inquisitive mind.
If something intrigues us then we want to know more! Using intrigue in your sales letter will encourage people to keep reading all the way through.
Example Intrigue Words

• Here's the thing...
  
• What would happen if...
  
• Guess what?
• Prepare yourself...
  
• How does that feel?

2.
Caution Words of caution can be used to encourage people to stop and think.
When someone makes a purchase there are of course emotional elements involved but there is also logic! Using caution can help people to think about your offer and come to the logical decision that it makes sense to buy.
Example Caution Words

• Hold on a minute
• You wouldn't believe...
  
• Think about it...
  
• It's not as simple as that...
  
• Consider this...
  

3.
Negatives Using negative words helps your visitor to understand more about their problem or issue they have.
It brings to to mind and therefore these words are emotive.
They bring the problem to a head and build a desire to overcome it.
Example Negative Words

• Something missing
• Still not working
• Tired of struggling
• Nothing happened...
  
• What am I doing wrong?

4.
Positives Using positives when it comes to talking about your solution (product) will reinforce the benefits that someone would receive by purchasing your product or service.
Again these words are emotive and will drive your visitor to take the action you want and purchase your product.
Example Positive Words

• Truly amazing
• Be able to...
  
• Finally allow me to...
  
• More than enough
• Great opportunity...
  

Sometimes people get concerned about using words like these in their sales pages.
They think that they being manipulative and trying to persuade people to buy! It can seem a bit slimy! Remember that your sales page may contain these trigger words but in reality if your product offers the solution to someones problem then offering this help should come naturally.
You will naturally use many of these words if you truly believe your product is worth what you state.
Selling any product should be about offering something to someone who really needs what you have.
Therefore you must believe in the products you sell and if you have created them yourself then you will know exactly why someone would benefit from purchasing it.
