To drive maximum reach on a minimum budget, what mix of awareness ad formats would you use?

To maximize reach on a limited budget, skippable in-stream ads and bumper ads are the most effective combination. Skippable in-stream ads offer broad reach at a relatively low cost because advertisers only pay when a user watches a significant portion or interacts with the ad. Bumper ads are short, non-skippable 6-second videos that are highly cost-effective for driving awareness due to their brevity and lower CPMs (cost per thousand impressions). Masthead ads are premium placements on the YouTube homepage, offering high visibility but at a much higher cost, making them unsuitable for a minimum budget. Non-skippable in-stream ads also have higher costs per view compared to skippable ads because users cannot skip them, which can quickly deplete a limited budget.
