The Impact Factor has come in for a lot of criticism over the years due to its inherent limitations, among them:

• Since the Impact Factor is derived from journals indexed in the Web of Science, no other journals can have an Impact Factor.
• Since the Impact Factor only looks at citations in the current year to articles in the previous two years, it only works well for disciplines in which rapid citation is the standard.
• It doesn’t take into account disciplinary differences in expected numbers of citations.
• There is no JCR for arts & humanities, therefore no Impact Factor for those journals.

Now, CiteScore has arrived to compete with the Impact Factor, luring users in with these benefits:

• It is free to access on the Scopus Journal Metrics website (JCR is a paid subscription.)
• It is calculated from the Scopus journal list, which is much larger than the Web of Science list and includes more social sciences and humanities journals.
• It provides a 3-year citation window, rather than the 2-year window of the Impact Factor. [https://library.osu.edu/researchcommons/2017/06/12/citescore-vs-impact-factor]

Cite score is the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in those same three years. While Impact factor is a measure of the frequency with which the average article in a journal has been cited in a particular year. (Retrieved from internet)

impact factor is related to journal, while citation is related to your article

Good short answer Dr Mushtaq Ahmed

Dear Abu Hashan

The major differences are:

CiteScore calculation is based on Scopus data, while Impact Factor is based on Web ofScience data. CiteScore uses a 3-year window whileImpact Factor adopts a 2-year window.

IF is for wed of sciences (ISI) and cite score is for Scopus.

In basic, there is no deference between they. Jsut IF is for 2 years ago and cite score is for 3 years ago.

IF in more important that cite score.

The 2 are almost the same cite score is based on data obtained from scopus whereas Impact factor is based on data obtained from web of science

cite score is from scopus and Impact factor is from data of web of science but cite score measuring on 3 years data while impact factor is from two years data.

The Impact Factor has had a long reign in academe , provided a unique, objective means of rating journals based on their citations and quickly became a standard measure of journal quality.

• The Impact Factor is derived from journals indexed in the Web of Science, no other journals can have an Impact Factor.
• The Impact Factor only looks at citations in the current year to articles in the previous two years..
• It doesn’t take into account disciplinary differences in expected numbers of citations.
• There is no JCR for arts & humanities, therefore no Impact Factor for those journals

CiteScore has arrived to compete with the Impact Factor, luring users in with these benefits:

• It is free to access on the Scopus Journal Metrics website (JCR is a paid subscription.)
• It is calculated from the Scopus journal list, which is much larger than the Web of Science list and includes more social sciences and humanities journals.
• It provides a 3-year citation window, rather than the 2-year window of the Impact Factor.

Almost both fullfil the purpose of the reserachers.

K. Karthik ;thank you M. K. Karthik for your interesting answer

To add with the above answers, the Scopus (Scimago) says that Cites per documents -2 years calculation uses the same formula as that of Thomson Reuters impact factor calculation.

cite score are related to the article and impact factor are related to the journal

Cite Score measures average citations received per document published in the serial and

The impact factor (IF) is a measure of the frequency with which the average article in a journal has been cited in a particular year. It is used to measure the importance or rank of a journal by calculating the times it's articles are cited. Both are related.

Please; How can we find the journals indexed in Scopus or Clarivate that haven't cite score or Impact Factor [New journals]?

Major difference between CiteScore and Journal Impact Factor: CiteScore calculation is based on Scopus data, while Impact Factor is based on Web of Science data. CiteScore uses a 3-year window while Impact Factor adopts a 2-year window.

CiteScore is a means to measure the average citations for a journal. This is calculated by the number of citations within the past three years divided by the number of all items published in the same years. The higher the CiteScore, the more valuable the journal is deemed to be.

The impact factor of a journal is calculated by dividing the number of current year citations to the source items published in that journal during the previous two years.

Major difference between CiteScore and Journal Impact Factor: CiteScore calculation is based on Scopus data, while Impact Factor is based on Web of Science data. CiteScore uses a 3-year window while Impact Factor adopts a 2-year window.
