In this monologue, Eric Deeran argues that ads cannot be overly long because uninterested viewers will simply stop watching, yet longer ads (typically 5–10 minutes) can achieve the highest Return on Ad Spend (ROAS) when they combine four key elements: a hook, an offer, proof, and education. He explains that this structure pre‑sells the audience, educates them, and produces more qualified leads compared to short, offer‑only ads. Deeran emphasizes that the educational component and proof are crucial for converting viewers into high‑quality prospects, even if the ad runs longer than typical formats.

My whole take on how long should an ad be is really based off the fact that an ad cannot be too long, in my opinion, because if somebody wanted to stop watching it, they would just stop watching it. But if they need to be convinced and pre-sold more, there's more ad for them to watch. And so some of our ads are 5 to 10 minutes long, and I have found that the best ROAS, not the cheapest booked calls, the best ROAS comes from the ads that are the longest, that do the most education in that process. And so you can start with some sort of hook, some sort of offer, and then you can roll into the proof and then the education behind it. And when you can combine all 4 of those things into the ad, You actually get a much more qualified lead because it's somebody who saw your offer, sees the proof, and then is also educated and you're teaching them something in that ad. You're not just blasting an offer to them.
