Each Facebook user who comments on your page posts is a potential sales opportunity, but manually replying one by one isn’t feasible or effective. The best way to take advantage of this type of engagement on your Facebook page is to reach out to commenters via your  Messenger chatbot, which can be done with the "Acquire Users from Comments" feature in Chatfuel. To begin sending  warm leads to your Messenger chatbot from Facebook post comments, all it takes is a few easy steps.

How to acquire users from comments

This Chatfuel feature allows your Messenger bot to send personal messages to people who have left a comment on a post published on your page. First, you’ll decide whether you want to message users who comment on one specific post, or any/all posts on your page. Then you’ll choose if you’d like to reply to all users who commented, or only to those that mentioned specific keywords.

Let’s say you wanted to reach out to users who mentioned “shipping” in a comment on your product-release post from last Tuesday. You could add a rule for your bot to send a coupon code via Messenger only to users in that fall into this group. The user will receive immediate value from the message, making them more likely to engage and become a bot subscriber. When they do, you’ll then have their information to use for future retargeting and potential conversion.

Note that this feature only applies to top-level comments, not replies, and only on the original post(s), not shares. Your bot will never message the same user more than once, no matter how many comments they may have left. Your chatbot must be connected to your page and set up to view replies to posts on that page for this feature to work properly.

Benefits of acquiring bot subscribers from comments

There are two key advantages of using this feature to automatically message users from Facebook comments with your bot. First, you’ll grow your list of bot subscribers. Users who comment on posts on your Facebook page have shown that they’re already interested in your brand in some way. Sending a Facebook auto reply to commenters brings these potentially warm leads to your bot, where you can initiate them into the conversion funnel and follow up with Re-Engage messages (formerly known as Broadcasts) in the future.

This feature is also a great way to qualify leads. Since commenters are already demonstrating interest in your business, sending them to your bot using this feature is an early step in the qualification process. From there, you can segment your audience even further based on how/if they reply, making it easier for you to retarget the most engaged users later.

How to set up this feature in Chatfuel

Setting up your bot to send an auto reply to comments on your Facebook page is simple. The first step is to create a rule in the Grow tab of your Chatfuel dashboard. This is where you decide which comments on which posts will trigger a response.
Then, you must create a plain-text message for your bot to send. The message will only be received by users whose comment matches the rule. They’ll be able to reply to it in Messenger, which makes them a subscriber, and their conversation with your bot continues from there.

Additional tips to keep in mind

Though setting up this feature in Chatfuel is easy to do, there are a few considerations to take into account in order to get the best results.

  • Avoid engagement bait. Although posting broad, oversimplified, or irrelevant questions like “Do you like dogs or cats? Reply in comment” may increase your engagement and give you more users to acquire, this quick boost isn’t worth it in the long run. Facebook will punish “engagement bait” with lower reach, so it’s best to only post authentically engaging content that’s highly relevant to your audience.
  • Only link to posts published on your page. The acquire feature won’t work for posts that were created solely 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.
  • Stickers and images cannot be tracked. This rule applies to the initial message your bot sends to a post commenter as well as their first reply. Both must contain actual text for Facebook to mark the conversation as substantial enough for the user to become a bot subscriber.
