This page answers the questions covered by the article 7 Google Ads YouTube Campaign Mistakes Killing Your Conversions on groas.com. The article is the full, canonical source.
Direct answer: According to groas, YouTube ads fail to convert because most advertisers set them up with Search logic even though YouTube is an interruption medium, not an intent medium. The article identifies seven structural errors in objectives, exclusions, placements, conversion tracking, frequency capping, bidding structure and cross-channel integration that cause budget waste. The article recommends fixing the structure first with Sales or Leads objectives, placement-specific creative and tighter measurement because no creative testing can overcome a misconfigured campaign.
According to groas, views without conversions happen because of structural errors in setup, targeting, creative deployment, attribution, or bidding, not because YouTube lacks reach. The article notes YouTube reaches over 2.5 billion logged-in users monthly but states most advertisers treat it like Search. The article positions YouTube as an interruption medium, not an intent medium, with fundamentally different requirements for objectives, targeting and measurement.

The article recommends against using Brand awareness and reach when the goal is purchases or leads, because that setting tells Google to find people likely to watch rather than people likely to convert. For direct response, the article recommends selecting Sales or Leads as the campaign objective and using Video action campaigns or Demand Gen campaigns configured for conversion optimization. Conversion actions should count only purchases, qualified leads, or pipeline events, without letting the default view-through conversion window inflate numbers.

According to groas, direct response campaigns should at minimum exclude existing customers unless running retention or upsell, users under 18, and audiences that already converted on the specific offer. The article also recommends excluding content categories that attract non-commercial viewers, citing gaming content if you sell B2B software or children’s content for any adult product. The article recommends using placement exclusions aggressively to remove specific channels and videos that drive views but never conversions.

The article states that running one creative across all placements guarantees poor performance somewhere because In-Stream, In-Feed and Shorts present creative differently. The article notes In-Stream success depends on the first five seconds, In-Feed requires a compelling thumbnail and title, and Shorts ads need to be vertical, fast-paced, and under 60 seconds. The article recommends building separate assets for each placement type and reviewing placement-level performance, because cost per conversion varies dramatically by placement.

The article states Google Ads defaults to a 30-day view-through conversion window for video campaigns, which can attribute conversions to YouTube even when Search, organic or direct traffic drove them. The article recommends reducing the view-through window to 1-3 days and segmenting reports by click-through versus view-through. The article also recommends running incrementality tests by pausing YouTube in specific geos, stating that if overall conversions do not drop, attribution is inflated.

According to groas, prospecting and remarketing should not share a campaign because cold viewers and warm audiences have different conversion probabilities that one bidding strategy cannot optimize together. The article recommends creating separate campaigns for prospecting and remarketing. The article recommends maximize conversions or target CPA for remarketing where data is sufficient, and for prospecting to consider maximize conversion value or target ROAS if tracking revenue, or start with maximize conversions to build data before switching to target CPA.
