Citation metrics:
There are general steps you can take to help with documenting your citation metrics:
Many databases let you set up an alert to notify you when an article has been cited. In most cases, you will need to set up an account to use the service.
Altmetrics uses non-traditional metrics and is a developing field that seeks to supplement established forms of citation analysis, such as article citation and journal impact factor, with usage measures that can be captured through social media, such as Twitter, Facebook, blogs, and bibliographic management tools like Mendeley and Zotero.
