A buyer-intent comment is a comment on a Facebook or Instagram ad that shows the commenter is close to a purchase decision. Instead of praise, criticism, or spam, it carries a question or statement that maps directly to the buying journey: "How much?", "Do you ship to Ireland?", "Is this in stock in medium?", or "How do I order?".
These comments are the most valuable thing that happens in the comment section of a paid ad, because the person has already paid attention to your creative and is now raising their hand. On a busy ad they are also the easiest to lose — buried under spam, tag-bait, and emoji noise.
ROAS Shield treats buyer-intent as a first-class signal. The classifier flags it, the comment is protected from destructive moderation (a buyer-intent signal vetoes any auto-delete and demotes it to a hide at most), and the comment is routed to you to convert with a reply or a private reply. The aim is to catch the moment of intent before the prospect cools off.
Buyer-intent detection is why generic ad comment moderation is not enough on its own: hiding noise is only half the job. The other half is making sure a real customer asking to buy never gets silenced by an over-eager rule. For more on how this works in practice, see the FAQ.
