How to Automate Facebook Page Comment Replies for Your Online Shop (Bangladesh Guide)

Every Bangladeshi Facebook shop owner has seen it: a boosted post gets 40 comments asking "price koto?" and by the time anyone replies, half those customers have already bought from a competitor who answered first. Facebook page comment auto-reply exists specifically to close this gap — and it's one of the most underused automation features among BD F-commerce sellers.

Why Comments Are a Different Problem Than Messenger DMs

A comment is public — everyone browsing the post sees whether and how fast you reply. An unanswered comment doesn't just lose that one customer; it signals to everyone else reading the thread that the shop is slow or inactive, which quietly hurts conversion on the whole post.

The Two-Part Fix: Public Reply + Private DM

The right way to automate comment replies isn't just a single generic public response. Sellzy's approach handles it in two coordinated parts, generated together so they stay consistent:

• A short public reply — quick, friendly, and specific enough to show the shop is active and paying attention (not just "check inbox" with nothing else).
• An automatic private DM — sent immediately after, actually containing the price and product details the public comment promised, so the customer doesn't have to wait or chase the shop down.

This matters because a public reply that just says "message korun" without ever following up with the actual details is a broken promise — and Bangladeshi customers notice when a shop's automated replies don't actually deliver.

Should Prices Be Public or Private?

This is a genuine strategic choice, not a technical limitation. Some merchants want prices stated publicly in the comment reply to build trust and reduce back-and-forth; others prefer to keep pricing in the private DM only, to encourage the customer into a direct conversation where upsells and combo offers can be discussed. A good automation tool should let the merchant choose this per-business, not force one approach.

What Happens to the Comment Thread Itself

Beyond individual replies, comment automation should also handle the basics correctly: tagging the commenter by name so they get a notification, keeping public replies short enough that a comment thread doesn't turn into a wall of text, and never leaving a comment completely unanswered — even a simple "thank you, details sent to your inbox" is better than silence.

Real Impact on Ad Spend

For merchants running boosted posts or paid ads, comment automation directly protects that ad spend. A comment that never gets a reply is a paid impression that generated zero return — automating the reply turns that same ad spend into an actual sales conversation.

Setting This Up

Sellzy's comment automation connects to the same Facebook Page as the Messenger AI, using one shared configuration for tone, language, and pricing rules — so a merchant sets their preferences once and it applies consistently across both comments and direct messages.
