I am struggling to calculate KEI (http://www.wordtracker.com/database_help/keihelp.html
) data from Google services using a perl script. My problem is legal not technical. To do the calculation I need the number of results returned and the monthly number of searches. The former I can get from the search API (http://code.google.com/intl/en/apis/ajaxsearch/web.html
) and the latter from the Adwords API (http://code.google.com/intl/en/apis/...olService.html
). The former's TOS require that any use of the API be freely available. The latter requires a small payment. My reading of the TOS seems to imply not only that the two data sources cannot be merged to provide KEI, but it almost looks intentional. I have tried to contact Google about this but without success. I cannot see why Google would want to block access to this data. I would have thought they would just add functions like this to the external keyword tool.
