Haha, thanks for the additional feedback! It is appreciated!
Thanks for the review. Those results are indeed not the best. Certainly not what is standard of this service. My guess would be the lack of movement for site 3 is either the result of its lack of on-page optimization for all 3 keywords (none of them are present anywhere on the page) or perhaps the site has been penalized a while back. The fact that the site appears to have over 19,000 backlinks pointed at it without any rankings to speak of strongly suggests it is either one of those two scenarios. You may be better off moving its high PR links to the first two sites for additional ranking improvements.
