Let the video SEO madness begin: Google Trends adds YouTube data

Google Trends added data from YouTube Wednesday, making it possible to see how a particular search term did on the video site. Google (s GOOG) added YouTube search data going back all the way to 2008 to Trends, which means that you can dig into the historical performance of search terms.
Users can either search for trends across Google and YouTube, or restrict searches just to YouTube. Here’s how “Harlem Shake” compared to “Gangnam” on YouTube over the last 12 months:

Trends has always been a fun tool to get a sense of what people are searching for, but it has also been helpful to optimize your own websites for Google search results. And with YouTube now being part of Trends, one can expect that many video publishers will frequent the tool to figure how to name their videos. In other words: Don’t be too surprised if your YouTube experience looks a bit more zeitgeisty and SEO-optimized from now on.
That being said, it makes a lot of sense for Google to include YouTube data in Trends, even for the purpose of tracking search trends across Google properties: YouTube has long been the second-biggest search engine on the internet, following Google proper, but ahead of Bing (s MSFT) and Yahoo (s YHOO).
