Welcome to the Q&A Forum

We have a self-grown tool at work but when I was on my own I used Link Assistant's Rank Tracker and it's pretty good when you get it setup right.  I reported month on month ranking changes.  Still probably the best & easiest way to do it for clients - but check out services like SERPS.com as well.

no but bold does, all be it not much Bold not using css, but overdoing this will look spammy to SE's as well as users

Hi Joseph, This is definitely not the ideal scenario.  If the two brands are targeting separate markets, why would the copy need to be the same?  Your two options would be to change the copy on one of the sites, or just redirect one to the site that is currently performing better. Hope this helps, Chris Wilson
