In scholarly and scientific publishing, altmetrics are non-traditional metrics proposed as an alternative to more traditional citation impact metrics, such as impact factor and h-index.
Altmetric BookmarkletThe Altmetric bookmarklet enables you to instantly see Altmetric data for any published research output with a DOI.
It’s quick, free and easy to install in just 3 simple steps.
The Bookmarklet only works on PubMed, arXiv or pages containing a DOI
It only supports publishers who embed Google Scholar friendly citation metadata on their pages by default, though we’re adding support for others. You can hurry along support for a particular journal by asking @altmetric for it on Twitter
Institutional Repository badgesWe offer free embeddable badges for repositories within academic institutions. They can be installed with just a few lines of code, and you can choose the style of badge you’d like to display. Users will be able to click on the badge to view the full details page for each research output.
Explorer for Academic LibrariansWe offer free individual access to the Altmetric Explorer for Publishers for academic librarians based within universities. This version of the Explorer can be used to browse and filter all of the research outputs in the Altmetric database, but does not include any institutional views, functionality or reporting. Please email us to request an account.
Our attention data is collated and updated in real time – meaning you start to get feedback on your publications almost as soon as they’re made available online.
Set up daily, weekly or monthly email alerts to receive regular updates on the attention surrounding content you care about, delivered straight to your inbox.
Powerful search & filtering
Browse all articles in the database, or filter by specific journals, publishers, or time last mentioned. Enter unique identifiers (including DOIs, ISBNs, PubMed IDs, arXiv IDs and Handles) to track specific items. Alternatively, search for individual outputs using keywords.
All of the data in the Explorer can be exported via Excel or an API to be used in other internal reporting or dashboards.
Badges for Individual ResearchersIndividual researchers can embed our badges for free too! It’s a great way to add context to your personal website or online CV, and can help demonstrate the reach of your work to visitors.
Once embedded you can click on the badge to view the full details page for each research output.
Showcase the influence of your work
Choose the badge style you want to display, and then grab the embed code from our site and add it to the html of your page.
Let us know you’ve done it (mailto email@example.com)! This way we can unlock the details pages to make sure everyone can see all of the original mentions of your work (otherwise they’ll just see the first 4 most recent ones from each source).

API for researchhttp://api.altmetric.com/
We’re happy to provide free access to the Altmetric API for academic research purposes. Please see the API page for information about the different levels of API access we offer.
If you’d like to request a key or have any questions about how the API works and the data you’re gathering, please email us.
t's free to use this API to fetch basic alt-metrics information about articles & datasets and to use that information in your own apps and mashups - just give altmetric.com attribution somewhere.
However, if you'd like to download the data in bulk, perform more complex queries, remove the rate limits and see more detailed data about articles then you'll need a commercial license (if you'd like to let us know about your use case you can reach us at firstname.lastname@example.org).
If you'd like to use the data in an academic research project then let us know and we can grant you a free license for non-commercial use.
