You can mix approaches and add other elements to make your headline more intriguing and believable. At a minimum, your headline should be:

1. Informative - the reader must know what s/he can expect in the body copy,
2. Useful – it should offer a benefit to the reader (target audience),
3. Offer a sense of urgency – it has to stand out from the crowd to ask the reader to carry on reading the article. The best way to do this is by showing the uniqueness of the article.

Now try it yourself. For example, alternate “at last” with:

• Finally,
• Ultimately,
• Resolved,
• Solved,
• Settled,
• Exclusive,
• Amazing...

and so on.

The point is to get the attention by standing out from the rest of the crowd. As you may have learned by now, it's pretty crowded on the internet.
