Outstream Ads

Outstream ads are video ads that run off YouTube, on websites and apps in the Google video partners network. Google describes video partners as a collection of sites and mobile apps from partner publishers that offer video content and extend your reach beyond YouTube. Its video partners article lists outstream as one of the formats available there, next to TrueView in-stream and 6-second bumper ads. Google's current overview of YouTube formats does not give outstream its own row, so confirm in your campaign whether the format is offered for your setup. Google's video partners article says the network works with Reach Planner, Unique Reach, and Active View. Reach Planner lets you estimate unique reach and cost before buying, which helps when comparing partner inventory with YouTube.

The mechanics differ from YouTube ads. An outstream unit is not tied to a video the visitor chose to watch. It sits inside an article or an app screen, and the video starts as the unit comes into view. Because it runs in someone else's page, the billing question is about viewability. Google's help says a video ad counts as viewable when it plays continuously for 2 seconds or longer, and viewable CPM bills only impressions measured that way. Whether viewable CPM is offered depends on campaign type and account, so check your bidding options. The viewability rule matters for what you pay. Under viewable CPM you pay only for impressions measured as viewable, and for video that means playing continuously for 2 seconds or longer, so a scroll past does not cost you.

Where it sits in your plan: it extends video reach to people who do not spend much time on YouTube, usually at a different cost than YouTube inventory. It works with the reach tools Google names for video partners, including Reach Planner, Unique Reach, and Active View. It does not replace in-stream. Attention is different, because people are reading or scrolling, not sitting down to watch, so the unit has to make sense quickly and without relying on sound. Placements on partner sites vary in quality. Review the placement report, exclude weak ones, using the exclusion tools your campaign provides.

Mistakes: expecting YouTube-quality attention and click-through from a unit in an article. Using creative that depends on a voice-over, so the muted version says nothing. Not checking which placements delivered, so the budget lands on poor sites. Mixing outstream results with in-stream in one average, which hides the differences. And forgetting to review the video partners setting, since in some campaign types opting in or out of partners changes where your ads appear. Creative should assume no sound and a short attention span. Start with the product or the problem on screen, add large captions, and keep the clip short enough to finish while the page is still in view.

To read results, look at viewable impressions, unique reach, view rate, and cost per thousand viewable impressions, and compare these against your YouTube placements in the same campaign. This week, open your placement report, find the video partners rows, and check the names. If the creative needs sound to land, add captions or a text overlay at the first second. Keep expectations on reach and cheap incremental exposure, and judge conversions by downstream effects rather than direct clicks. Judge it as incremental reach. If outstream adds unique people at a lower cost than YouTube without hurting results elsewhere, keep it; if not, switch the partners setting off.
