What is Cobaltmetrics?

Cobaltmetrics crawls the web to index hyperlinks and persistent identifiers as first-class citations. We analyze a wide range of websites to reveal insightful links between documents.

Cobaltmetrics goes deeper than backlink databases and altmetrics aggregators to help you report on all types of content: publications, books, clinical trials, patents, software artifacts, derivative works, etc. The web is our corpus, and our URI transmutation API collates citations to all known versions of a document.

Web-scale citation tracking

Altmetrics for all

Our work on altmetrics stemmed from a simple observation: existing altmetrics providers were not alt- enough.

Cobaltmetrics goes deeper than other altmetrics providers. We mine data in over 180 languages, we unroll shortened URLs from over 175 shorteners, we crack open URLs to extract persistent identifiers, and we convert between more than 50 types of identifiers.
