John Benjamins offers Kudos to its authors

Kudos is a web-based service, funded by publishers and institutions, that helps researchers to maximize the visibility and impact of their published articles. Kudos provides a platform for assembling and creating information to help search filtering, for sharing information to drive discovery, and for measuring and monitoring the effect of these activities.

We supply Kudos regularly with lists of journal articles and book DOIs to facilitate linking those to your Kudos profile. Needless to say, it remains your choice whether you want to use this free service and if so, how actively you want to use it.

Through the author dashboard in your Kudos profile you can see how many people clicked on the Kudos link of your article after you shared that on LinkedIn, Facebook, or Twitter. Recently, we have arranged for usage statistics of our publications on the JB e-Platform and IngentaConnect to be fed to Kudos on a daily basis. This allows you to see how your actions promoting or mentioning your publication impact on the number of full-text views.

Kudos provides information on how to use the service with optimal effect, on their general page for researchers and their user guide.

In addition to this, here are a few more suggestions:

When you share a link to your publication on social media, make sure to use the link that Kudos provides for this purpose, because that is the link that is tracked for the metrics on your dashboard.

In the “What’s it about?” box you could simply copy the abstract as it is included in the article itself, but that information is already fairly widely distributed. Instead you could use this space to provide a lay summary in order to explain to people outside your own field or outside of academia what the publication is about.
You could do this in English (or the language the article was written in), or you could use the opportunity to provide a summary in the/a language that the article was about.
Using the possibility to link other resources to your article, you could point to a video with an explanation in a signed language even, if that is of interest to you and your readers.
