-Tired of writing repetitive code to send the same analytics data to all your different tracking services? Or formatting the same data slightly differently for each service, like using ["eventAction"](https://developers.google.com/analytics/devguides/collection/analyticsjs/field-reference#eventAction) for Google Analytics but ["event_name"](https://developers.intercom.com/reference#event-model) for Intercom?
+Tired of writing repetitive code to send the same analytics data to all your different tracking services? Or formatting the same data slightly differently for each service, like using [`eventAction`](https://developers.google.com/analytics/devguides/collection/analyticsjs/field-reference#eventAction) for Google Analytics but [`event_name`](https://developers.intercom.com/reference#event-model) for Intercom?
 
 Use Crosslytics for a unified event definition and analytics reporting API: Define events once and report them to all your analytics services with a single call. We've also abstracted the services themselves into a pluggable [Tracker](#trackers) architecture so you can use only the services you need and quickly add support for new ones.
