Hoover and Scopus started their own indexes to better measure content and usage of their databases, revealed E-Content.
Hoover’s Index of the public and private and non-profit companies and associations will measure the most popular and searched companies in the database. The index "is based on an algorithm that takes into account the search trends of business professionals, including both organic and internal searches on Hoover’s site, as well as business-related searches conducted via major search engines."
Scopus also created their own h-index, which will consider number of publications of an author over a period of time and number of citations for each paper. The abstract and citation database will also be able to tell if " the h-index is dependent on a few highly cited papers or that the author’s papers have a relatively consistent volume of citations. "
