To improve your altmetric scores you need to create an online presence and share information about your work and your research outputs online.
There are many ways to do this such as:
Blog about your articles or work and ask others to write blog posts about your work.
Become active on Twitter and tweet links to your articles and other work.
Use social networks for researchers
Create a profile and add your publication list to social networking sites for researchers, such as Academia.edu, ResearchGate and Mendeley.
Register for researcher IDs
Register for ids such as an ORCID id, ResearcherID and keep your list of publications up-to-date.
Make all your research outputs available online
Make all your research outputs including data, code, videos and presentations available online by using on content hosting tools such as figshare, Dryad, YouTube, Vimeo, SlideShare, SourceForge or GitHub.
Deposit your work in an institutional or subject repository
Deposit your work in the Florida State University institutional repository: DigiNole, or a subject-specific repository for example, arXiv, a repository for physics and mathematics.
How to embed altmetrics in your website
All three altmetrics services provide a means for embedding your altmetrics data into your personal website.
PlumX: PlumX also provides cut-and-paste code that allows you to embed both item- and researcher-level widgets on your website. On the author or itempage, you'll see an "Embed Widget" button in the upper-right hand corner of the screen. Click on the button and, on the next page, choose what you want to appear on your widget. Then, at the bottom of the page, copy the code from the "Code Snippets" section and paste it into your website where you want the widget to appear.
Impactstory: You can use cut-and-paste code to embed a badge and link to your Impactstory profile in your website. Or, you can use your profile's open data to embed the metrics themselves in your website. (This process is a bit more technical, but allows for a lot of customization.) You can add your profile- or item-level JSON data files to your website, using your favorite language to parse the code into XML or HTML. See this tutorial for more information on how to do that.
