ImpactStory has been around for a while – we used to recommend it in our “Stand Out and Be Counted” sessions as a great showcase for a researcher’s all-round profile and a way to track altmetrics. It then went through a period as a paid-for service but now, happily, it’s re-launched and free!
It’s extremely easy to set up a profile if you have an ORCID (and if you don’t, here’s plenty of reasons why you should) and you then get an instant profile that pulls in your publications and all kinds of information about the impact these are having (or not). The ImpactStory blog outlines what you can find there and how you can use it. Looking at an example profile gives an idea of the wealth of evidence that the site covers.
