Looks interesting. A few questions:
1. What will it cost?
2. Do you plan to support multiple datacenters and multiple search engine URLs? For example, google.co.uk returns very different results to google.com. Those of us targetting multiple countries will want to track multiple country-specific search engines.
3. Will there be any kind of API, allowing me to retrieve the data directly into my own programs? Or will it only be accessible through your web application?
Thanks
