You can use RSS Ground to make automated posts and trigger IFTTT. But you can also use IFTTT services to collect targeted content to your RSS Ground personal feeds.
Here is a step-by-step user guide on how to set up a content collection:
1. Create at least one personal feed in RSS Ground (Guide)
2. Sign up for IFTTT (Guide)
3. Set up an applet with RSS Ground as an action (Guide)
As soon as targeted content appears in the chosen IFTTT service it will be automatically added to your RSS Ground personal feed as a separate item.
