This page answers the questions covered by the article [How To Run YouTube Ads In 2026: Frequency, Formats, And Strategy](https://groas.com/post/youtube-ads-strategy-2026-frequency-formats-guide) on groas.com. The article is the full, canonical source.

**Direct answer:** According to groas, YouTube advertising in 2026 rewards advertisers who manage frequency aggressively, choose formats deliberately, build audiences from first-party data, and coordinate standalone campaigns with Demand Gen. The article recommends format-specific weekly caps and resolving cross-campaign overlap with audience exclusions or consolidation, because Google does not deduplicate frequency across campaign types. For measurement, it advises against trusting view-through conversions or in-platform ROAS at face value and instead using branded search lift, geo-holdout incrementality tests, and GA4 assisted conversions.

## What frequency caps should I set for YouTube ads by format in 2026?

The article recommends starting caps at 3 impressions per user per week for bumper ads, 2-3 per week for non-skippable 15-second ads, and 3-5 per week for skippable in-stream for awareness or 5-7 for retargeting where the audience is already warm. It states that frequency caps are less critical for in-feed because the user actively chose to engage, but advertisers should monitor anyway. According to groas, performance for non-skippable ads typically degrades noticeably after three to four exposures per week.

## Why am I overexposing the same viewers when I run YouTube and Demand Gen together, and how do I fix it?

The article states Google does not combine frequency across a dedicated YouTube awareness campaign and a Demand Gen campaign that also serves on YouTube. As a result a user might see a bumper ad 3 times from the YouTube campaign and 3 more times from Demand Gen, reaching 6 total impressions in a week when the intended maximum was 3. The article recommends fixing this with audience exclusions to prevent Demand Gen from targeting the same segments as standalone YouTube campaigns, or by consolidating YouTube delivery into Demand Gen alone and managing frequency from one campaign.

## When does skippable in-stream work on YouTube and when does it waste budget?

The article describes skippable in-stream as the workhorse format where advertisers pay when someone watches 30 seconds (or the full ad if shorter) or clicks. It states the format works for storytelling, brand awareness with measurable engagement, and retargeting sequences, but wastes budget with broad targeting and generic creative. According to groas, if view rate drops below 20%, the hook is failing, and creative must hook within the first five seconds as skip rates have climbed with increased ad load.

## How should B2B advertisers use YouTube ads to drive demo requests?

The article positions B2B YouTube advertising primarily as an awareness and consideration play, using skippable in-stream and in-feed to educate a target account list uploaded via Customer Match. It recommends measuring success through branded search lift and demo requests, not through direct click-to-convert attribution. According to groas, advertisers should pair YouTube with Search campaigns that capture demand created by the video exposure.

## How should I measure YouTube ads now that view-through conversions are unreliable?

The article advises not to use view-through conversions as the primary success metric, stating Google's default view-through window is generous and often claims credit for conversions that would have happened anyway. Instead, it recommends branded search lift compared week-over-week against YouTube spend, incrementality testing with geo-holdouts where YouTube is paused in specific regions, and GA4 data-driven attribution focused on assisted conversions rather than last-click. According to groas, YouTube-reported ROAS in Google Ads should not be trusted at face value and should be cross-referenced with first-party data.
