[This research was initially published on Tubefilter.com in June 2017}
YouTube’s promotional algorithms have changed drastically over the years. In the beginning, the algorithm was largely reliant on metrics that were easily manipulated, like views, clicks, likes, and comments. And the goal was primarily to drive more views.
In 2013 that changed in a big way. YouTube shifted the primary goal of its algorithm to reward “Watch Time”, or time spent on the YouTube platform.
In a previous study here on Tubefilter, we discussed what metrics YouTube considered on the publisher side to calculate Watch Time. We then wrote a follow up article last year in June, “Reverse Engineering The YouTube Algorithm (Part I),” which shared a number of insights we found in determining the metrics that drive Watch Time. Then, in the fall of 2016, Google released a white paper, “Deep Neural Networks for YouTube Recommendations,” which lead to Reverse Engineering The YouTube Algorithm (Part II), further shedding light on what powers the YouTube algorithm.
Now, we’re thrilled to share with you our latest research into the YouTube promotional algorithms in our presentation, “Cracking YouTube in 2017.”
Some of the big highlights from the presentation include:
Videos that are between 7 and 16 minutes perform up to 50% better than videos that are shorter or longer.
Videos with an average view duration of 5 – 8 minutes receive the most views.
There is no correlation between views and length of title, number of tags, or length of description.
There is a strong correlation between number of tags and number of creator suggested videos in that creator’s suggested video column.
But that’s not all! You can check out the entire presentation, replete with interesting data points and tangible takeaways, right here:
