Widget that can do the following.
1) Enter the URL
2) The URL is sent to google, so maybe you can do a site:[url removed, login to view] search to get all posts (maybe theres a quicker way of doing this?)
3) All the contents of the website (all the posts) is analysed.
4) The content is matched to a number of keywords in a database (Approx 200-300)- For example spaghetti, cheese, tomato.....
5) A result is given in the form of a widget that people can embede into their site. For example.
According to our widget, [url removed, login to view] covers 22% of our keywords.
If you have any questions, please ask me to clarify.
