Attention sources tracked by Altmetric

Our mission is to track the conversations around research outputs online wherever they're happening. To that end we're constantly looking for new sources of data.

Specifically what we're looking for are sources that regularly link to scholarly content, though in some cases like news outlets and policy documents we're also able to perform text mining to try to match research mentioned (but not linked to) with published scholarly articles.

Altmetric currently tracks the following attention sources for mentions of research outputs. Where possible we surface the original text of each mention, and in some cases are also able to provide demographic data on the author of the mention. It's crucial to us that all of our data is fully auditable, and that you can see not only how many people are talking about the research, but who they are and what they're saying.

You can check out the news sources page on the Altmetric website for the latest list of news sources that we track. This list currently extends to over 14,000 English and non-English global news outlets.

We maintain a manually curated list of over 16,000 academic and non-academic blogs. These are tracked automatically via RSS feeds. More information about blogs can be found here.

Altmetric tracks mentions of research outputs in podcast episode descriptions and content:encoded metatags. We track a curated list of podcasts covering various subjects, via their RSS feed. By adding podcasts, we help you track attention across more sources, plan and manage research impact, report on engagement to funders and leadership, and showcase your publication's broad reach.

Altmetric tracks mentions of research outputs referenced in seminars, through a partnership with Cassyni. We track the written references list of each seminar, not the audio, video or transcript content. Seminars are also indexed as research outputs, each with its own DOI.
