Conversations vs ThruPlay Optimization

In short: Both are engagement-style optimizations that don't need a pixel to work, but the medium and the effort required afterward are completely different. Conversations captures a live chat message that a person on your team has to handle; ThruPlay captures video watch-through, a passive attention metric with no follow-up needed. The split shows up in ad format, in whether your business owes the user a response, and in how close each sits to actual buying intent. Choose Conversations when you want a direct, if informal, path to a sale; choose ThruPlay when you're testing creative or building awareness with no staff needed to respond.

Conversations Optimization

Delivers to people likely to start a messaging thread with your business in Messenger, Instagram Direct, or WhatsApp after tapping the ad.

Used with click-to-message ads, this optimization counts a conversation once someone sends a first message, and Meta hunts for users who habitually do. It works well in markets and categories where buying happens over chat, or where a form feels heavier than a question. The common mistake is having no response system: unanswered threads still count as results, so the metric looks healthy while leads rot.

ThruPlay Optimization

Buys video views that run to completion, or to at least fifteen seconds on longer cuts, instead of counting brief glances.

Meta charges on impressions but delivers toward users predicted to watch through, which filters out feed scrollers. It fits awareness, brand storytelling, and creative testing where watch depth is the signal you care about. The misread is treating ThruPlays as intent. A completed view costs little and predicts almost nothing about purchase, so never judge a conversion campaign by video metrics alone.

Side by side.

The differences that actually change what happens in your account.

	Conversations Optimization	ThruPlay Optimization
Ad format it requires	Click-to-message ad on Messenger, Instagram, or WhatsApp.	Video ad in an awareness or video-focused campaign.
Action that counts as a result	User sends a first message after clicking.	User watches the video through, or fifteen seconds or more on longer videos.
Requires a response from you	Yes, someone or a bot must reply or the result produces nothing.	No, the result is complete the moment the watch threshold is hit.
Signal type	Direct engagement with your business, but unstructured.	Passive attention to creative, no direct interaction with your business.
Where it typically sits in funnel	Mid to bottom funnel, since messaging implies some buying intent.	Top funnel, brand or awareness stage.
Requires pixel or website tracking	No, native to the ad or messaging platform.	No, native to the ad's video-view tracking.
Failure mode	Unanswered messages count as results while producing nothing for the business.	High watch-through with no connection to actual purchase or lead behavior.

What actually separates them.

Conversations requires the user to actively initiate contact with your business, while ThruPlay only requires passive attention to a video, so Conversations sits much closer to buying intent even though neither needs a pixel.

A Conversations result creates ongoing work for your team, since someone has to reply; a ThruPlay result creates no follow-up obligation at all, since watching a video to completion ends the interaction.

Conversations only runs through click-to-message ad formats, while ThruPlay only applies to video ad creative, so the two are tied to entirely different ad formats and can't really substitute for each other.

ThruPlay campaigns are usually run for brand or awareness goals early in a campaign strategy, while Conversations campaigns are typically run when you want a direct, if informal, path to a sale or booking.

An unanswered Conversations thread still counts as a successful result despite producing nothing, while a ThruPlay result is honest about what happened, a full watch, even though that watch predicts little about purchase behavior.

Which one should you use?

Use Conversations Optimization when

You want a direct line of interest capture where the user actively reaches out, not just watches passively.
Your audience buys through chat and a quick question-and-answer beats a video ad.
You have staff or a bot ready to respond to every message quickly.
You're further down the funnel and want engagement that signals real intent, not just attention.

Use ThruPlay Optimization when

You're running a brand-awareness or storytelling campaign and want to know if the creative holds attention.
You have no staff available to handle a flow of inbound messages right now.
You want to build a video-viewers audience to retarget with a stronger offer later.
You're early in a campaign strategy and haven't built out a messaging or lead-capture flow yet.

Common questions.

Can a ThruPlay campaign also generate Conversations?

Not directly. ThruPlay is a distinct ad format from click-to-message ads, so if you want both video engagement and message-based interest, you need separate campaigns using each format.

Why does my Conversations campaign cost more per result than my ThruPlay campaign?

Sending a message is a more deliberate, higher-intent action than watching a video, so it naturally costs more per result. That's expected, not a sign of an inefficient campaign.

Is ThruPlay a good choice if I want leads?

Not directly. ThruPlay only measures video watch-through with no interaction with your business, so if leads are the goal, Conversations, Lead, or Complete Registration optimization sits closer to that outcome.

Do unanswered Conversations results hurt my campaign performance?

They don't change how Meta counts the result, since a sent message counts regardless of your reply. But if you never respond, Meta's optimization keeps buying the same low-value behavior and your business sees no benefit despite a healthy-looking results count.

Or stop choosing between them.
