If a webpage contains a video, Google tries to determine how relevant the video is to the rest of the content on the page. When Google cannot determine a video’s relevance, it returns a “Google could not determine the prominent video on the page” error, as shown below.

To resolve this error, Google suggests you first resolve other video indexing issues revealed in the Search Console. Once done, follow the below steps to help Google determine the most prominent video on your webpage.
Fixing the ‘Google Could Not Determine the Prominent Video on the Page’ Error
1 Move Your Video Above the Fold
If your webpage contains a single video, move it to the top of your webpage so your visitors can view it without needing to scroll down. If your webpage contains multiple videos, move the most important one to the top.

2 Resize Your Videos
After moving your video to the top of the page, navigate to Google Search Console and paste the webpage URL into the URL Inspection tool. Once done, click Enter and then click on the TEST LIVE URL button, as shown below.

Next, click VIEW TESTED PAGE > SCREENSHOT, as shown below.

You will be presented with a screenshot of your webpage. You can use the screenshot as a guide to resize your video to match the rest of the content.
3 Request Google to Reindex the URL
The final step is to request Google to reindex the webpage. To do so, return to Google Search Console and paste the webpage URL into the URL Inspection tool. Once done, click REQUEST INDEXING, as shown below.

The “Google could not determine the prominent video on the page” error message is not always bad news. As Google mentioned, it is okay if your website is not designed to display a video at the top of the page or identify one of your videos as more prominent than the rest.Â
