Startup Idea: Keyword Tracking Software for Content Sites and Blogs

Startup idea to develop a software to efficiently track and manage large volumes of keywords for content-based websites or blogs. The system will prevent duplication of content by keeping a checklist of keyword topics that have been covered.

I work in the online marketing space, specializing in content sites or blogs. One part of our strategy is to provide large amounts of content over time.

In other words, for example, we might eventually have a site about a particular topic (health, gardening, or whatever) and have 1,000 articles on the site, each covering a specific keyword found either through keyword tools or through knowledge about our niche (forums, books, etc.) we need software that would help us keep track of which keyword topics we have covered so we don't end up with duplicate content.

There used to be a product called Keyword Strategy, but it's not around anymore. There are sites like SEO Moz that will track rankings for a smaller number of keywords, but we need a much bigger database (or whatever you call it) and are particularly concerned with having a big checklist of keywords - not just tracking rankings.
