The title of your manuscript is usually the first introduction readers (and reviewers) have to your work.
Therefore, you must select a title that grabs attention, accurately describes the contents of your manuscript, and makes people want to read further.
If database search engines can find your journal manuscript, readers will be able to find it too.
This will increase the number of people reading your manuscript, and likely lead to more citations.
Importantly, adding more words to these titles to make them more specific does not seem to deliver a proportional gain in information.
Consider expanding “Intelligence” to “An Overview of Contributions to Intelligence Research” or changing “Orthorhombic Bi Fe O3” to “Creation of a new orthorhombic phase of the multiferroic Bi Fe O3.” The additions, drawn from the article abstracts, just make explicit what is already largely implied.
Furthermore, it depends on the publication year from which the articles are taken.
The mean title length of 12.3 words just quoted was for 2012.
However, to be effective, Keywords must be chosen carefully.
The title of a research article has an almost impossible remit.
