Jamali H, Nikzad M. Article title type and its relation with the number of downloads and citations. Scientometrics 2011;88(2):653-661
The authors wondered if the type of article title affect the number of citations and downloads an article receives. They found that articles with a question mark in their title tend to be downloaded more but cited less than descriptive or declarative titles. No significant correlation was found between title length and citation, whereas titles with colon tend to receive fewer downloads and citations.
