I came across a great blog entry that offers links from various search engines and social networking sites that help you predict keyword trends. Google trends, Google Insights for Search , Twitter Search and Twist were among the many solutions available for the SEO expert who has his eye on future trends. While the solutions mentioned above offer graphs and charts that can help you identify trends, there is also a certain art to determining which keywords may trend higher in the near future. This process is part science, and art. I think of keyword trending in the same way I think about stock picking. There is lots of data out there for the savvy investor, but when it comes down to it, there is no perfect science that will predict which stock will rise up and which will fall. There is some art to picking a raising stock, just like there is some art to discovering future keyword trends.
