Welcome to the Q&A Forum

This is my favorite, Very helpful ideas! http://www.seomoz.org/blog/8-ways-to-buy-links-without-buying-links

Thank you, Keri! Will try this at once.

hmmm.... that sounds kind of sneaky... ...Not an answer to your question but... maybe Owner B should just get a new domain and 301  his URLs over?

Depends on your use case but this is a good resource: http://www.whichmvt.com/ Personally I really like VWO: http://visualwebsiteoptimizer.com/ I like the way you don't need heavy code changes to run tests.

Thank you for the inputs. I fully agree it depends on me and my products - this is why I am asking for ideas to find metrics rather than asking for numbers. Thanks!

Or they could allow one, totally non-spammy sig link once you get to a certain point... i.e. 10,000 moz points or something. I doubt spammers would hang around that long to get a link

Just came from ses ny it was great

Exactely. Sometimes I am not aware of an answer or question due to to much traffic here in the Q&A section ... I kind of loosing the overview 

I agree with Link Research Tools - there's a wealth of data that can be used to help in Link Building Efforts. Watch all the videos first otherwise you are going to be drowning in link data. The Competitor Analysis Tools (compare upto 25) is amazing, and a lot better then SEOmoz competitor Tools. Check out the Link Alerts tool as well. The service will automatically crawl upto 16 different backlink sources (including GA Referral data) and let you know when you have a new link. I also use this tool for website audits - very handy. Not a substitute for any other tool, but very complimentary.
