The funnel is not dead. But it has a growing competitor that most marketers are not measuring correctly, and the data from 2025 suggests that competitor is winning in several categories.
The tactic is simple enough to describe in one sentence: post content that generates comments, then move the sales conversation into those comments rather than into a traditional funnel sequence. The execution details are what make it work.
Here is the format in practice. A marketer posts something genuinely useful — a tip, a breakdown, a counterintuitive observation — and includes a line like "Full breakdown in the comments" or "Step-by-step is in Comment #1." The engaged audience migrates to the comments. The marketer delivers the promised content there. The resulting comment thread signals relevance to the algorithm, extends organic reach, and creates a genuine interaction record with everyone who responded.
The interaction record is the key variable. Someone who commented on your post has demonstrated an interest level that someone who visited your opt-in page has not. Comment-based engagement creates a warmer basis for a subsequent direct message or offer than almost any other cold-to-warm mechanism on social platforms.
The approach works particularly well in three scenarios:
When the topic is nuanced enough that people want the full explanation but the feed format limits depth. "How I got our email open rates to 41% — breakdown in the comments" gets more traction than "How I got our email open rates to 41% [link to blog post]" because the comment stays on the platform and the algorithm rewards that.
When the audience is in the research phase rather than the buying phase. Comment threads let people ask questions and get answers publicly, which builds social proof and reduces hesitation simultaneously. Other people reading the exchange are essentially watching a mini sales conversation unfold.
When the product or service requires some trust-building before a transaction is appropriate. Consulting, coaching, and high-ticket services benefit most from this approach, because the comments allow the seller to demonstrate expertise before making any ask.
The limitation is that this approach is slower than a well-optimized funnel. It builds an audience over weeks rather than capturing leads in hours. But the leads it produces tend to convert at significantly higher rates than cold opt-in traffic, which changes the unit economics in ways that pure volume comparisons miss.
The funnel handles volume. The comment-first approach handles warmth. The best social media strategies tend to use both, with the comment-first method feeding the top of the funnel rather than bypassing it entirely.
