Bob Stone, one of the world’s best known copywriters said “Your first 15 words count more than the 15,000 words that follow!”

Any serious copywriter (and most successful bloggers out there) agree with the statement and actually put the advice to use every day. Why?

Because it’s the truth, the whole truth and nothing but the truth. Those first few words that you start with (your headline) are often written in haste. Yet, they count for 50% of the success of your entire copywriting project.

Unfortunately, in today’s rush, it’s hard to spend 90% of your time coming up with a winning headline. This is especially true if you’re mass-producing content on a day-to-day basis (like bloggers and article writers).

The good news is that formulae exist that you can use to speed up your headline writing process… But before I give the formulas to you, let me say this: If you really want your copy to generate maximum response, you MUST spend a considerable amount of time writing, fine-tuning and testing your headlines.

How to use these headline formula

The way to use these formulas for maximum effectiveness is to take the time to write at least 5 different headline versions using each formula. This will force your creative juices to flow and give you enough headlines to split-test in your marketing campaign.
