Facebook Keyword Automation — FAQ
How does Facebook keyword automation work?
Facebook keyword automation monitors your Facebook Page for specific keywords you define — in post comments or in Messenger inbox messages. When a user comments or sends a matching keyword (e.g., 'LINK', 'PRICE', 'FREE'), the system instantly sends them a personalized Messenger DM with your response. The entire process takes under 1 second from keyword to DM delivery. ReplyKaro uses the official Meta Graph API and Messenger Platform API for safe, compliant automation.
Can I use multiple keywords for the same Facebook automation?
Yes. ReplyKaro supports multiple keyword triggers per automation — you can set LINK, SEND, and YES to all trigger the same Messenger DM. You can also set different DMs for different keywords on the same post. This lets you segment your audience by intent and give each group a different message.
What are the best keywords for Facebook automation?
The highest-performing Facebook automation keywords are: LINK (most versatile), FREE (for lead magnets), PRICE (for sales and D2C), INFO (for services), ORDER (for food and products), BOOK (for appointments), RECIPE (for food creators), DOWNLOAD (for digital products), DEMO (for software and courses), CALL (for coaches and consultants). Short, action-oriented words in ALL CAPS perform best. Match the keyword to what you're offering in the post.
Does Facebook keyword automation work on both comments and inbox messages?
Yes. ReplyKaro's Facebook keyword automation works in two modes: (1) Comment trigger — someone comments your keyword on a post, they receive a Messenger DM; (2) Messenger inbox trigger — someone sends your keyword to your Page inbox, they receive an automated Messenger reply. You can run both simultaneously from the same automation or set up separate ones.
Is Facebook keyword automation safe for my Page?
Yes — ReplyKaro uses only the official Meta Graph API and Messenger Platform API. These are the APIs Meta provides specifically for Page automation. No browser bots, no password sharing, no scraping. Rate limits ensure you never exceed safe thresholds. ReplyKaro has zero Page suspensions among its users.
Can I see which keywords are driving the most DMs?
Yes. ReplyKaro's analytics dashboard shows DM delivery counts per automation and per keyword trigger. You can see which keywords have the highest comment rate and conversion rate, and optimize your captions and video CTAs accordingly. Analytics are available on all paid plans starting at ₹99/mo ($3/mo).
How is Facebook keyword automation different from Instagram keyword automation?
Facebook keyword automation sends Messenger DMs and can trigger from both post comments and inbox messages. Instagram keyword automation sends Instagram DMs and triggers from post or Reel comments. Both use the same ReplyKaro dashboard — you can run keyword automation on Facebook and Instagram simultaneously from one account.
Is Facebook keyword automation free?
Yes. ReplyKaro's Free Forever plan includes Facebook keyword automation with 1,000 Messenger DMs/month at no cost. No credit card required. Paid plans start at ₹99/mo ($3/mo globally) for 15,000 Messenger DMs/month and 15 active automations.
Also Do Instagram Keyword Automation
One ReplyKaro account manages Instagram and Facebook keyword automations from the same dashboard. Run both platforms simultaneously.
