Although we have no need to be afraid of duplicate content, there is no doubt we are still afraid of it. But what SEOs are best at, outside of link building, is making sure a site, especially large dynamic ones, don't have major duplicate content issues and they feed the appropriate pages to the search engines at all times.
So when Google launched their Google TV and asked webmasters to optimize their sites for TV - you as an SEO need to know the implications for duplicate content.
The good thing is that most of you are aware of the issues. If you already have a mobile site or printer friendly URLs and so on - you know the risk and what strategies you should take to prevent duplicate content. We covered it in fine detail over here - so read that, and then come back here.
Google offered several tips:
What does "optimized for TV" mean?
- Text is large enough to be viewable from the sofa-to-TV distance.
- Site navigation can be performed through button arrows on the remote (a D-pad), rather than mouse/touchpad usage
- Selectable elements provide a visual queue when selected (when you’re 10 feet away, it needs to be really, really obvious what selections are highlighted)
So useragent detect, and serve up a new CSS file for those accessing your site on Google and maybe even Apple TV.
