We're tracking now and the only comparison I have to previous numbers are overall internet sales (which are up 61% since April 1)
This is the only really meaningful metric in the campaign. The website is a vessel, not a trophy.
There are plenty of video references as to the limitations of PR as any meaningful type of metric for business _ I would start there by politely explaining this and sending them to a URL from Matt Cutts which explains this, to backup your explanation.
I would leave the links on the directories, but make sure you are very vigilant about anyone you link out to.
I, for one, would only link out to a handful (less than 5) total directories that are worthwhile for consumers, are aged and trusted. Any directory that asks you to link back, if this is the case, is not worth linking with at all.
