We’ve started adjusting the ranking of videos in YouTube search to reward engaging videos that keep viewers watching. […] The experimental results of this change have proven positive — less clicking, more watching. […] As with previous optimizations to our discovery features, this should benefit your channel if your videos drive more viewing time across YouTube.

It appears that the reason this page from a little-known website is able to rank amongst the bigger players is that the content itself is more focussed. It talks about how to name images for SEO, whereas most of the other pages are more general guides to image SEO—which all presumably mention the importance of naming images correctly, amongst other things.
Ok I had a recent video that literally a week later was on page one for keyword which was competitive and now it’s fallen way off serps. I’ve dug around and heard that GGle/YT in Feb did an algo change. All I know is I was so happy and then depressed as nothing in the video had changed…Any comments. And I haven’t read the comments yet perhaps some info…
SIDENOTE. The endscreen needs to be baked into your video during the editing process. For our endscreen, both the subscribe circle and “next video” sections are blank. When you add end screen elements, it’ll fill those sections. The subscribe sphere should be 196 x 196 px and the video or playlist rectangle is 410px x 230px. Here’s a free template you can download.
Google updates its search algorithm frequently. For example, on February 23rd, 2016, Google made significant changes to AdWords, removing right-column ads entirely and rolling out 4-ad top blocks on many commercial searches. While this was a paid search update, it had significant implications for CTR for both paid and organic results, especially on competitive keywords.
Thanks for the post. I found you through a G search for how to rank a YouTube video. I honestly think with the recent G update, they are trying to force their adwords and YT and everything else they own to the user. So I think that the new “niche site” is going to be YT videos. I lost a ton of rankings to my niche site over the weekend. My entire website went from average 800 UV a day to 10… Really made my heart sink. Just as I was starting to do well with SEO ha ha.

Quora is a website where users generate the content entirely. They post questions via threads and other users answer them. It’s basically a yahoo answers type social network that works like an internet forum. Both threads and answers can receive “upvotes” which signify the answer was worthy and popular. The answers with the most upvotes are put at the thread’s top.
Your the first person that I have found that has mentioned a “video search” in Google. This is a GREAT point that I will continue to look for and title in the right way to acquire these searches. I do mostly local SEO, and many of the terms that I want to target are not viable as “video searches” per say. I have found that combining reviews with local search terms works well, and that videos can rank about 5x faster than traditional SEO when done correctly.
Keep in mind, this will often mean shifting the focus of your business from more general to more specific products or services. For instance, instead of exclusively offering general home renovation services, you could consider specializing in "one day bathroom renos" or "custom kitchen makeovers." These more specific keyword phrases will likely be much easier to rank for, which will mean you can start ranking that much faster.
