Several journals have more than an impact factor and also, some of them have a fake impact factor. I want to know how to avoid the fake journal and get the rue impact factor.
you should notice if the journal has a Scopus Indexed, InfoBase Index IBI and Thomson Reuters then enter for each factor online and check the journal, another thing usually there are more than one article curried the same name, so should check the ISSN for the chosen journal
You can consult that information in SJR website. All the journals included in the SJR are indexed in Scopus/Elsevier /data provider, so they could help you with this issue: https://www.elsevier.com/solutions/scopus/content/content-policy-and-selection http://suggestor.step.scopus.com/suggestTitle/step1.cfm
