Each Facebook user who comments on your business’s page posts is a potential sales opportunity. But replying to each one manually isn’t scalable, and won’t work as a very effective sales funnel, either.

If you want to take advantage of the engagement on your Facebook page, it’s time you heard about our Acquire Users from Comments feature. It’ll trigger your Messenger chatbot to automatically message commenters. It can instantly engage prospects by answering questions, offering discounts, or a number of other actions to move them along the sales funnel.

To begin sending warm leads from your page to your bot, all it takes is a few easy steps.

How to set up this functionality in Chatfuel

You can do it in minutes! You’ll just have to decide two things:

  1. Which post(s) will it apply to? Do you want your bot to message commenters on one specific post, like one you created for a special campaign or announcement? Or do you want it to apply to all posts on your page? (Be careful with the latter option; it can get spammy.)
  2. Which comments will it apply to? You can have your chatbot message everyone who comments on the post(s) you chose above. Or, it can message only those whose comments include a keyword or phrase.
You can have your chatbot respond to all comments on a post(s), or only those that include a keyword/phrase that you set.


You can make these selections (also known as creating an autoreply rule) in the Grow tab of your Chatfuel dashboard. After that, you just have to create the message you want your bot to send those commenters. Make sure it’s engaging gets users to respond! If they do, they become a bot subscriber, which means you can reach out to them again in the future. You can also choose to send new subscribers to a relevant block in your bot once they reply, regardless of exactly what they said.

You can follow along step by step with the video below, or find more information on our documentation page for Acquiring Users from Comments.

Additional tips to keep in mind

Setting up this feature in Chatfuel is easy to do. However, there are a few additional points to take into account so you can get the best results.

  • Your bot must be set up properly. Make sure it’s connected to your business page. Also check that it’s set up to view replies to posts on that page.
  • Consider disabling the Get Messages CTA. Facebook might automatically enable this option for your post, but beware: It can make things more confusing for users. Basically, it adds another CTA (Send Message) besides the one in the text of your post. Users might not understand what you want them to do, so they may not engage at all.
  • Avoid engagement bait. Posting broad or irrelevant questions like Do you like dogs or cats? Reply in comment may get you more comments. But it’s not worth it in the long run. Facebook will punish this engagement bait with lower reach. That’s why it’s best to only post authentically engaging content that’s highly relevant to your audience.

And don’t forget these rules about which types of posts and comments will work for this feature, and which won’t:

  • Only link to posts published on your page. This feature won’t work for posts that were created just for an ad and only exist in Ads Manager (“dark posts”). You can acquire users for your bot from comments on a boosted post, but only if it was originally published directly to your page.
  • Only top-level comments will trigger the response, not replies. And it’ll only work on the original post, not shared versions of it. Also note that your bot will never message the same user more than once, no matter how many comments they may have left on that post.
  • Stickers and images cannot be tracked. For these acquired users to become bot subscribers, the first interaction must include actual text from both sides. Your bot’s first message must have some text, and same for the user’s first reply. Stickers and images won’t count for this, so use that first message to encourage a text response from users.

Similarly, you can also set your Chatfuel bot to respond to users who review your business on Facebook. As long as you’ve enabled the ability for users to leave reviews in your page settings, a bot can reply to anyone who submits one.

  • For positive reviews, your bot can instantly send a message thanking the user for their feedback. You could even include a discount code or other perk to show your appreciation. Again, make sure that first message encourages some kind of response from the user so they can become a subscriber.
  • For negative reviews, your bot can offer a freebie or a discount code to make up for their experience. You could even use the Live Chat plugin to connect them with a human agent to resolve the issue and learn what you can do to improve.

Setting up this feature is simple. Head to your Facebook page’s inbox. Find Automated Responses, then toggle one or both of the options under Respond to Feedback to On.
