Scholarly Publishing vs. Predatory Publishing: Altmetrics

Altmetrics are a very broad group of metrics, capturing various parts of impact a paper or work can have. A classification of altmetrics was proposed by ImpactStory in September 2012,[34] and a very similar classification is used by the Public Library of Science:[35] "
Viewed - HTML views and PDF downloads
Discussed - journal comments, science blogs, Wikipedia, Twitter, Facebook and other social media
Saved - Mendeley, CiteULike and other social bookmarks
Cited - citations in the scholarly literature, tracked by Web of Science, Scopus, CrossRef and others
Recommended - for example used by F1000Prime[36]"

"The SCImago Journal & Country Rank is a publicly available portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database (Elsevier B.V.). These indicators can be used to assess and analyze scientific domains. Journals can be compared or analysed separately. Country rankings may also be compared or analysed separately. Journals can be grouped by subject area (27 major thematic areas), subject category (313 specific subject categories) or by country. Citation data is drawn from over 34,100 titles from more than 5,000 international publishers and country performance metrics from 239 countries worldwide. The SJCR allows you also to embed significative [sic] journal metrics into your web as a clickable image widget" This website currently covers ~60 journals.
