Google Ads and YouTube are different platforms, and different data aggregation methods are used by each. Therefore, we hereby inform you that there is a difference between the search criteria of the advertisement and the search criteria for YouTube, and we also would like to inform you of the cause of the additional changes in the indicators.
1. Aggregated over time: Korean time (Google Ads) vs Pacific Time (YouTube)
There is a difference between Google Ads data aggregation base time and YouTube base time. YouTube typically aggregates data based on Pacific Time, but Google Ads does so based on the time zone you set for your account. Since the Korean advertiser's account is based on Korea Time (Seoul), there is a time difference of 8 hours between that and Pacific Standard Time.
Therefore, if you were to compare the real-time data or the number of views on the same date, the number of views between the two platforms may vary. That's why we recommend comparing data between YouTube and Google Ads at a generous interval of roughly a week.
2. Data reflection time: real-time oriented (Google Ads) vs. Approximate 72 hours (YouTube)
Google Ads aims to reflect real-time data, which is typically processed in under three hours. On the other hand, YouTube can take up to 72 hours to update data as a result of filtering duplicate aggregations, malicious repetitive queries, etc.
3. Aggregation criteria: Ad view (Google Ads) vs Video view (YouTube)
There is a difference between how Google Ads aggregates ad views and how YouTube videos are aggregated.
Here's how Google Ads aggregates ad views:
When the movie is less than 30 seconds long: Users must watch the advertisement until the end in order to count the views.
Video length longer than 30 seconds: Users must watch the ad for more than 30 seconds so as to count the views.
Regardless of the length of the video, it is tallied by views when the user interacts with the ad (e.g., clicks on the ad).
On the other hand, the number of views on YouTube itself is aggregated by means of YouTube algorithms regardless of views on advertisements. Thus, there may be a difference in the number of views on advertisements.
In addition, for Google Ads, the participation in advertising which is considered meaningful is counted by the number of views. For example, ad clicks could also be aggregated by views, and if you see an ad more than once, they can be aggregated in duplicate.
On the other hand, YouTube filters the number of views through either repeated or malicious repeatability systems. As a result, the number of views in the video itself may be less than that of advertising views.
