I'm certain that, in my corner of the web, a lot of queries lost other features like the featured snippets and now have a youtube videos box that is typically quite large, it pushes the #1 natural non-video result to the bottom of the page and sometimes below the fold.
A typical web page ranks for many search terms and only loses(or gains) some traffic when the special feature changes. In my case I can see that entire sections of my web pages no longer draw as much traffic once the Youtube videos get top priority in the SERPs. I qualify a section as a heading and the content related to that heading. Sections that greatly improved the number of visitors a page receives suddenly don't even if the page continues to do well otherwise.
SO - can't beat em, join them?
I'm not suggesting to bust out the video making equipment and become a youtube creator, I'm referring to possibly including one of the top videos into my content for a term I once got traffic for but no longer do. Call it future proofing or a placeholder if you will. Perhaps one day I will want to create videos and I'll already have web content to feature it from by replacing other videos with my own. For now, I don't.
Pros
- I'd expect the time on page to increase.
Cons
- the default iframe does nothing for the metrics of a webpage but videos can be embeded via html5 using the object tag.
- Random video suggestions made by Youtube at the end of a video may cause the visitor to leave my site but they can be turned off
- The videos are not mine and might disapear from youtube but Search Console now reports about videos embeded on your pages, yours or not, so a replacement can be found
- My visitor privacy is compromised as the video records data from my site but the video can be served from Youtube's nocookie domain so that it records nothing unless the visitor pushes play.
I'd want these videos lower on the page below MY content, of course, and only one per page for a very specific aspect of my page topic. An aspect that google shows the video ahead of my page anyway. Each of the cons seem to have a solution... is it time to include more videos when Google prefers videos for the given query?
It feels like it's time to revisit embeding 3rd party videos. They can help my visitors and my site metrics, is there anything else to worry about after the recent updates? I'm already testing it on several pages that lost traffic after losing the featured snippet to a video section. So far.... not enough data.
edit: Google is encouraging this judging by the fact they added a new section to search console called video discovery.
