Google seems to be capitalising on its results pages real estate by now showing two video listings side-by-side in the space normally occupied by a single search result.
In the past, individual video results occupied the place of an antire search listing, and wereÂ accompanied by a title, a short, one-line snippet pulled from the YouTube page for that video, the duration and average user ratings for the video, as can be seen alongside. This is still the predominant listing format for most universal search results.
However, some searches seem to now yield a single result with two videos placed side-by-side, as seen in the screenshot below. Both the videos are still pulled from YouTube, and both are accompanied by a short title, but are without any description snippet or ratings information and instead just contain information about the duration of the video.
While both videos in the screenshot above do seem equally relevant to the query, that does not seem to be the sole influencing factor for such a layout of the results, as the two videos in the first example shown above-right are also equally relevant in fact, but are still listed one below the other.
It is not clear at present how Google determines whether videos should be presented in this layout or another. It may be something to do with the currenct nature of the query or it may be that both videos score the exact same relevance points according to the Google algorithm and can therefore be clubbed together, even though they are varied in content and come from different useer accounts.
