The term impact factor is based on WoS data base (Thomson Routers) and it is for journals those indexed by WoS. Accordingly no one can say IF for any other journal. When Scopus do something similar they called it Citescore (NOT IF) event is similar way of calculation.

The term: Google-based Impact Factor is created/used by those journals not indexed by WoS or Scopus and want to show some statistics.

While scientific journals were part of the academic community more than 350 years ago, the concept of research metrics is relatively recent. Beginning with Garfield’s development of the Impact Factor in the mid- 1960s, research assessment metrics have exploded over the decades, beyond journal citation-based metrics to include entities such as authors and articles.

The difference between World of Science impact factor and the Google impact factor is the data they rely on. The Google relies on altmetrics, that is, metric material that is accumulated from the net, and  the WoS impact factor divides the number of citations a journal receives by the number of publication of this journal in the last two years, and the data, in this case, is selective and based on data indexed in the database.
