YouTube Masthead

The YouTube Masthead is the large video unit at the top of the YouTube Home feed. Google's format overview says it is reservation-only: you book it through a Google sales representative, and it serves on the YouTube homepage. On desktop it autoplays muted for up to 30 seconds. On mobile it autoplays muted for the full video, and on TV it autoplays where supported. Google notes there is no maximum video length and recommends more than 10 seconds. You can buy it by CPM or by CPH (cost per hour). Google lists the Masthead as a CPM or CPH product, and cost per hour means you pay for the time the unit is booked, not for each impression. The right pricing model depends on how many people you expect to reach in the slot.

Reservation means you are not bidding in the auction. You agree with the sales team on a market, dates, and a price, and the placement is reserved for those dates. The campaign types listed are YouTube Masthead on CPM, YouTube Masthead on CPH, and Reservations. You cannot start one by yourself from the usual campaign flow. Expect a conversation about audience, flight dates, creative approval, and measurement. The unit can show to everyone who opens the home feed in the booked market, so audience control is looser than in the auction. Google says rate estimates and impression goals are set with the Google advertising team. Ask early what measurement is included, including whether a brand lift study is offered, so that you can plan the success measure before you sign.

It exists for moments of mass reach: product launches, movie releases, big sales, and brand events. It is not for ongoing performance work. A small business with a local service has no use for it, and a reserved placement on the home feed is out of range for most small budgets. The relevant comparison is to other awareness buys such as TV, billboards, and large display takeovers, not to search or Meta conversion campaigns. Because the unit is on the homepage, it can include a follow-up experience on the watch page. Prepare that page with a clear next step, whether it is a product page, a store locator, or a reminder to subscribe.

The mistakes are expecting auction efficiency and granular targeting. Pricing is set with Google's advertising team, and you pay for a reserved placement rather than entering an auction. Others: building creative that needs sound to land when the unit starts muted, and putting the main message after the 30-second desktop cut-off. Judging success by cost per click or cost per action also misses the point. The right yardstick is reach, brand lift, search interest, and sales in the weeks after the flight. Avoid treating the Masthead as a stand-alone event. Support it with search ads on your brand name, because a large awareness moment creates a spike in people searching for you, and you want to capture them.

If you are considering it, decide first what the unit must do in measurable terms: lift brand awareness by a stated amount, or push a launch-week search volume. Ask the representative which brand lift measurement is available and what the reporting will include. This week, write the one-page brief: market, dates, goal, and the 10 second version of the creative. If the budget does not support a reservation, use skippable in-stream or Demand Gen for reach on a smaller scale. Plan the aftermath. Track search interest, site visits, and sales for several weeks, and compare with a similar period without the buy.
