There are several factors that you need to keep in mind when pursuing publishing opportunities such as:
Impact Factors: This ratio will reveal the number of citations divided by the number of articles
Journal acceptance rates can help to reveal important statistical information about the selectivity of a journal.Low acceptance rate, high rejection rate journals are considered the best and most prestigious journals. This information can be found by looking at the journal itself to see if they are listed or by searching the journal's website to see if the information is available on their website.
The prestige and reputation of the association, society, or organization publishing a journal can be a determining factor. In therory, the most prestigious scholarly associations publish the best, most important, research in the field and therefore their journals have more prestige and weight than others. There are a handful of scholarly journals that are known by reputation throughout the world, such as JAMA, The New England Journal of Medicine, Science and Nature. These scholarly journals are known and read by both people within the scholarly discipline and people outside the scholarly discipline
This is another method which could be used to assess the quality of a journal. High readership and circulation could be markers of a journal's quality and/or popularity. Circulation numbers can be often be found at the journal publisher's website.
