There is no definitive answer to this question, as it depends on the context and the specific goals of the copywriter. However, in some cases, a short headline can be an effective way to capture a reader’s attention and get them to read further.
One example of when a short headline can be useful is when the writer is trying to create a sense of urgency or excitement. In these cases, a headline that is just a few words long can be more effective at getting the reader’s attention than a longer headline.
Another time when a short headline can be useful is when the writer is trying to create a sense of simplicity or clarity. In these cases, a headline that is just a few words long can be more effective at getting the reader to understand the main point of the article.
Ultimately, the best way to know whether a short headline is the best copywriting trick for you is to experiment with different types of headlines and see which ones work best for your specific goals.
