How to set up reddit keyword alarms

1. Go to the subreddit of your choice, for example r/Entrepreneur
2. In the search bar, enter the keywords you are interested in, for example
   "invoicing" AND "as a service"
3. Modify the URL of the search result page by inserting .rss between the last slash and question mark. For example, change
   https://www.reddit.com/r/Entrepreneur/search/?q=
   to
   https://www.reddit.com/r/Entrepreneur/search/.rss?q=
   Keep the rest of the URL unchanged and add &restrict_sr=1 at it's end.
4. Copy the new URL and subscribe to it in your favorite RSS reader.
   

That would be it! Posts with relevant keywords will keep popping in.
