I’ve noticed that video carousels are taking up more and more real estate in the SERPs. I want to start a YouTube channel for our software company, but I’m not sure how to optimize the videos so they show up for "How-to" searches in Google. What are the most important ranking factors for Video SEO in 2025, and do I need to host the videos on my site too?

Video SEO is now just as much about "Chapters" as it is about keywords. When you add timestamped chapters to your YouTube description, Google can index those specific segments as "Key Moments." This allows your video to appear in the SERPs for very specific long-tail questions. You should also embed the YouTube video on a dedicated page on your site and wrap it in "VideoObject" Schema markup. This tells Google exactly what the video is about and increases the chance of a rich snippet. Focus your titles on the specific problem you are solving—"How to..." titles still dominate the video carousel.
Do you prioritize the "Thumbnail" design for click-through rate, or are you more focused on the keyword density within your transcript and description?
Don't ignore the "Engagement" metrics like Likes and Comments. Google views these as signals of content quality, which directly impacts your ranking in the carousels.
Spot on, Nancy. We always end our videos with a specific question to encourage comments. That "social proof" is a massive signal to the algorithms that the content is helpful.
Jason, the thumbnail is arguably your most important SEO factor for YouTube specifically. If your CTR is low, YouTube will stop suggesting the video, which kills its search authority. However, for Google Search ranking, the transcript is king. We use AI to generate a perfect transcript and then place it on the blog page below the embedded video. This gives Google's crawlers plenty of text to index while providing the users with the video they want. It’s a dual-pronged approach that targets both the "readers" and the "viewers" effectively.
