Zoetrope is a new web tool being jointly developed by Adobe and researchers at the University of Washington. The general idea is to allow users to view the Internet over time. Think of it as the Wayback Machine on steroids. Sarah Perez does a good job writing about Zoetrope in ReadWriteWeb.
Yet, it's the following video that does the best job of explaining Zoetrope.
Could Zoetrope be used as a SERP tracking tool?
If Zoetrope could capture specific search engine results pages (SERPs), then it could be a very powerful SERP tracking tool.
Let's say I have 10 high value keywords for which I want to be highly ranked on Google. Using Zoetrope I could conceivably capture the daily SERP for each keyword and link it to the appropriate destination page. This would allow me to see if changes to my page had any impact on SERP ranking for that keyword.
I could even create 'lenses' for my competitors and review how they've tweaked their site to help influence SERP rank. Zoetrope could provide an unparalleled level of detail and analysis for a savvy SEO practitioner.
Yet there's a big, actually huge, 'if' in the statement above. I doubt that Zoetrope is or even could capture every SERP. But that doesn't mean there's not a way to do this. In fact, I think it provides a pretty interesting business opportunity.
Want Zoetrope to help you track SERP for a group of keywords? Simply sign-up for a subscription and they would begin to capture the information. Toss in a 30 day free trial to get the ball rolling and I think you'd have a number of people clamoring for and using Zoetrope for SERP tracking.
