Every author search for indexed journals to publish his/her article in, and tries to select a journal that is covered by a number of abstracting and indexing services.
Indexation of a journal is considered a reflection of its quality. Indexed journals are considered to be of higher scientific quality as compared to non-indexed journals. The indexed journals have expanded online presence, improved article discoverability, and reputable for high-quality publication in their own field.
Since the main purpose of a journal is to be accessible to a wide audience, once it is indexed by a database, it is immediately made available to all users of a database that has indexed that journal.
Being accessible has a direct impact on a journal’s reputation; if a journal is available for a large number of academic population, it will be considered a reliable source of high-quality information in a certain field.
Every researcher will look to established, well-known databases as the first activity in his/her studies; if a journal is indexed in a known database in that researcher’s field, he/she will find that easily and read it. This increases that journal’s readership.
