Performance & cost

• Runs in 1-3 minutes depending on the number of keywords and results
• Uses another actor internally (reddit-scraper) so costs include that actor's compute time
• Each keyword triggers a separate search run

FAQ

Can I add my own subreddits? The subreddit list is built into the actor. For custom subreddits, use the Reddit Scraper Turbo actor directly.

How often should I run it? For monitoring, schedule it daily or hourly. The sortBy: "new" setting gives you the latest posts each time.

Does it catch every mention? It searches Reddit's search API, which covers most posts. Very new posts (under a few minutes old) may not appear in search results yet.
