OMICS Group international free journal's impact factor indicates the frequency with which the "average article" published in a given scholarly journal has been cited in a particular year or period and is often used to measure or describe the importance of a particular journal in a specific field.

OMICS Group international journal's impact factor for 2013 would be calculated by taking the number of citations in 2013 from articles that were published in 2012 and 2011 and dividing that number by the total number of articles published in that same journal in 2012 and 2013.

OMICS Group international journal's are among the best open access journals in the world. They publish the most comprehensive, relevant and reliable information based on the current research and development on a variety of subjects. This information is published on our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also based on review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports. Inclusion of these publications provides innumerable opportunities to the editors and publishers to manipulate the ratio used to calculate the impact factor and try to increase their number rapidly.
Impact factors have a huge, but controversial, influence on the way published scientific research is perceived and evaluated. Numerous criticisms have been made of the system but:

•The above mentioned Impact factors are useful metrics for comparing the OMICS Group international journals and their influence within the field.
•These Impact factors are not infallible measures of OMICS Group international journals quality.
Furthermore, a journal that allows long lag time between submission and publication, it might be impossible to cite articles within the three-year window. Indeed, for some journals, the time between submission and publication can be over two years, which leaves less than a year for citation. On the other hand, a longer temporal window would be slow to adjust to changes in journal impact factors. Whereas OMICS Group international journals follow rapid review process to publish the manuscripts as quickly as possible after acceptance. In OMICS Group international journals, the editorial office is dedicated to ensure the peer review process of the manuscripts by the eminent editors and the reviewers to raise the quality of publishing.
Different ways how the impact factor is measured is described below:

5 Year Journal Impact Factor

The 5 year journal impact factor is the average number of times the articles published in that journal in last 5 years has been cited in the Journal Citation Reports year: It is calculated by dividing the number of citations in the Journal Citation Reports year by the total number of articles published in previous five years. The 5 year impact factor is available only for Journal Citation Reports 2007 and following years. The 5 year Impact factor can be calculated using an earlier Journal Citation Reports year as a starting point by following these instructions.

Aggregate Impact Factor

The aggregate impact factor for a subject category is calculated using the same method as the impact factor for a journal, but it also includes the number of citations for all journals in the category and the number of articles from all journals in the category. An aggregate impact factor of 1.0 implies that the articles in the subject category published in recent two years have been cited once on an average. The median Impact factor is the median value of all journalsí impact factors in the subject category. The impact factor extenuates the significance of absolute citation frequencies. It alleviates the advantage of large journals over small journals because large journals circulate a larger body of citable literature. It also mitigates the benefit of frequently issued journals over less frequently issued ones and of older journals over newer ones. For the reason that the journal impact factor offsets the advantages of size and age and it is a helpful contrivance for journal evaluation.

Impact Factor Trend Graph

The Impact Factor Trend Graph exemplifies the Impact Factor for a five-year period. To view the graph, click the Impact Factor Trend button at the top of the Journal page.
* Unofficial 2013 Impact Factor was established by dividing the number of articles published in 2011 and 2012 were cited in 2013 based on a search of the Google Scholar Citation Index database, by the number of articles published in the previous two years (2011 and 2012).
X = the number of times, articles published in 2011 and 2012, were cited by indexed journals during 2013
Y = the total number of "citable items" published by that journal in 2011 and 2012.
2013 impact factor = X/Y
