That is interesting. But i feel that increase in number of key phrases may not always positively correlate to conversion. It might result in a higher traffic but not better conversion, as a large number of key phrases may not really convert.
It may help if you find out the key phrases that lead to good conversion, and monitor them for fluctuations in ranking and traffic to your site.If you could also monitor the origin(location) for traffic via those key phrases, it would help further.
