Just popped into my email, I haven't used it and their reg tools are expensive but this one is free:
http://ontolo.com/link-building-tools/BacklinkMonitor
QuoteHere's what we monitor for you to see how you're performing against your competitors:
* Google Backlink Totals
* Google PageRank
* SEOMoz MozRank
* SEOMoz Backlinks
* SEOMoz Authority
* SEOMoz Trust
I've not used the product but know the two guys behind it. Garrett used to work at Marketsmart Interactive and took over editorial duties from Andy Beal when he left there. Very smart, savvy guy, was wasted working for them and now he is doing very good things in the link building space.
I could always speak to him and see if we can get a "group" discount?
