The Google team has quietly announced changes to the thumbnail selections for videos that might spell the end of the Rick Roll.

In December YouTube announced changes in a post titled ‘A YouTube for All of Us‘. Outside of the strange capitalization the post contained the following statements.
Improved thumbnails – To make sure your thumbnail represents your video, your choices will now be selected algorithmically. You’ll still have three thumbnails to choose from, but they will no longer be auto-generated from the 25/50/75 points in the video index.
More accurate video information – Our Community Guidelines have always prohibited folks from attempting to game view counts by entering misleading information in video descriptions, tags, titles, and other metadata.
Recently, the Google Research Blog explained a bit more about Smart Thumbnails on YouTube.
… our previous system of choosing thumbnails from the 25, 50 and 75% marks in the video, which often led to arbitrary, uninformative or sometimes even misleading images, is now a thing of the past. When a new video comes to YouTube, we now analyze it with an algorithm whose aim is to pick a set of images that are visually representative of the content of the video.
Clearly Rick Rolling would be Exhibit A and any engineer working on a video algorithm would use Rick Rolls as a use case for development.
Is this the end of Rick Rolling? Perhaps. Or maybe it’s a continuing chess game as Rick Rollers figure out ways to beat the new thumbnail algorithm.
Never gonna give you up … never gonna …
AJ KohnOctober 03 2008 // SEO + Technology // Comments Off on Google Deploys Multiple Algorithms?
Over the past few months it seems like Google might be experimenting with having multiple search algorithms in the field at once. We’re all well aware (or should be) of the A/B practice that Google has implemented for years. Google dances, when a major algorithm update goes live, are a normal part of SEO life.
But what if that changed?
What if Google decided to have 3 or even up to 5 search algorithms in the field at the same time. That’s what I’ve been seeing lately, though they seem to have stopped in the last week or so.

In a given hour I would see at least 3 different search results for terms related to my used books blog and those related to a number of my clients. (And yes, I had personal search off.) I’m now kicking myself for not documenting these very different search results.
This could simply indicate an accelerated testing framework for the algorithm or it could be an attempt to thwart web spam and those that try to ‘game’ the algorithm. Think about it. If there was no one dominant algorithm in the field at any given time it would become difficult to ‘game’ Google.
You might find a weakness to exploit in one algorithm but do you scale a program if it only represents 30% of the search traffic? Could Matt Cutts have found a creative way to prevent web spam?
As always there’s little concrete evidence of what is actually going on under the hood at Google. And the silo driven nature of Google’s workplace ensures that most at Google wouldn’t know either. I do find it interesting that during the same time period many search tools became inoperable. SEO Chat has the following message for a number of their tools.

Even if Google is not going to field multiple search algorithms, it seems clear that their testing mechanisms have evolved. The speed in which the algorithm evolves might be accelerating. As such, it makes it more difficult to determine when a true algorithm change has occurred.
If Google does implement a multiple algorithm strategy it would help encourage sites to focus on basic SEO principles which would wind up being good for search engines and users alike.
