How Fast Replies Improve ROAS: The Data Behind Comment Automation

If you're spending tens of thousands on paid ads and letting comments sit unanswered, you're bleeding performance.

Most eCommerce brands obsess over ad creative, targeting, and CAC—but overlook the one channel where customers literally ask to buy: the comment section.

Here’s what the data shows about fast replies, customer trust, and ad ROI—and how automating replies can unlock revenue you’re already paying to reach.

Why Ad Comments Matter More Than You Think

Shoppers don’t always click right away. Many leave a comment first:

• “Is this true to size?”

• “How long does shipping take?”

• “Is this a scam?”

According to Sprout Social's research, over 75% of consumers expect brands to respond within 24 hours—but most never hear back. And by the time a human does respond, the window to convert has often passed.

On Meta platforms, comments aren’t just visible—they're prioritized. Negative or unanswered comments can harm brand trust, lower engagement, and even reduce your ad’s reach via the algorithm. Meta confirms that engagement quality affects ad relevance and delivery cost.

The Link Between Reply Time and Conversion

Faster replies = more revenue. Here's why:

• Trust builds instantly. A quick, helpful reply shows you’re a real brand—not a dropshipper.

• Reduces friction. Most comment questions are purchase blockers (fit, shipping, returns). Eliminate them in seconds.

• Amplifies reach. Engaging with users boosts post activity, improving visibility across Meta’s algorithm.

• Keeps buyers in-platform. A smooth reply → DM → checkout flow increases conversion without bounce risk.

One study from Womply found that responding to social media comments can boost customer advocacy by up to 25%.

Why Manual Replies Don’t Scale

Most teams try to keep up manually, or outsource to social agencies. But here’s the problem:

• They’re not online 24/7

• They don’t always get your tone or product details right

• They can’t catch momentum during a high-performing campaign

Even a short delay can have a compound negative effect: the wrong comment stays up, unanswered, and others see it first.
