First-Touch vs Last-Touch for YouTube: Which Videos Introduce Buyers and Which Close Them

The same buyer journey can give two very different answers to "which video made this sale?" It depends on the credit model. Under last-touch, the credit goes to the last video the buyer clicked before converting. Under first-touch, it goes to the first video that brought them in. On YouTube, where buyers often watch several videos over days or weeks, those can be completely different videos.

Knowing which model a report uses, and being able to compare, is one of the core things to check in a Trakyo alternative. See the full list in what to look for in YouTube revenue attribution.

A simple example

A viewer finds your channel through a broad video about a common problem. A week later they watch a case-study video. Two days after that they click the link in a video about your offer and book a call.

• First-touch credits the broad problem video.
• Last-touch credits the offer video.
• Shared models split the credit across all three.

None of these is "true." Each answers a different question.

Why last-touch alone misleads YouTube creators

Last-touch is the default in many tools because it's simple. But on YouTube it systematically undervalues the videos that bring new people in. A broad, top-of-funnel video can introduce a large share of your eventual buyers and still score close to zero in a last-touch report, because buyers rarely click through on the first video they watch.

If you only look at last-touch, you'll be tempted to make more "closing" videos and fewer of the videos that fill the pipeline in the first place.

Introducers vs closers

The most useful view is the comparison:

• Introducers score high on first-touch and low on last-touch. They bring new people in.
• Closers score high on last-touch and low on first-touch. They turn warm viewers into calls.
• All-rounders score well under both.

A healthy content plan needs both kinds. The comparison shows you which kind each video is.

In VidWorth: each channel has a stated credit model, so every per-video figure comes with the model it was computed under. VidWorth can also score every video under all of its supported models at once and rank them by where the models disagree most. That surfaces your introducers and closers. The comparison is read-only and doesn't change the channel's setting.

How to check a single sale

When a per-video number looks surprising, open one sale and look at the path: every content touch in order, and which video each model would credit. In VidWorth, any booking or payment can be opened this way.

Quick answers

Which model should I use? Pick one for reporting so numbers stay consistent, then use the comparison to make content decisions.

Can I change models later? Yes, but quote the model whenever you share a number, or old and new reports won't line up.

Does this apply to booked calls too? Yes. The same journey logic applies to calls as to payments. See how VidWorth tracks a video from view to booked call.
