Welcome to the Q&A Forum

Hi Brian, There is so much confusion surrounding this very common topic because Google has repeatedly changed their stance. The thread Amber has pointed to on Linda's forum quotes the most current Google policy on this. Linda's thread doesn't link to the source of this, so I will here: http://productforums.google.com/forum/#!category-topic/business/S6APN5ijnOQ And here is the complete language of what Google staffer, Jade, wrote: Verified business owner of a page, and is your business moving locations? Here's what you do.__Edit your address in Google Places for Business or in the Google+ page admin area, whichever you are using to manage the page. This will either make a new page or edit the address on the existing page. It may take a week or two after editing your address before you see an update. At this point, you may need to go through a verification process again. Don't worry -- this is normal.__If you see a page that's still got the old address, click on Report a problem and mark that location as closed. Provide the link to the new address or information about the new location if possible. You can find more instructions on closing a location here: http://goo.gl/YZIjq*Now, remember, following the above steps must be followed up by a citation cleanup campaign. You need to find all web-based references to your old address and edit them so that they reflect the new address. This is very important.

I might use the keyword difficulty tool to determine which jobs I would not want to accept  -  due to lack of time and staff - to attack a brutal, maybe impossible target. I might also use it to get some idea of how difficult a job might be. However, the best data that you might have is a chart that compares keyword difficulty of your previous clients, their relative starting point in the SERPs and the amount of money that was required to produce whatever result was achieved. Then a variable that only you can answer is your relative effectiveness in different niches.  If I was given the job of competition for "hydraulic jacks" I might know exactly how to approach that and have industry knowledge, quick resources and allies at hand - these will enable me to jump right up the SERPs.  However, if I get the job of attacking "easy chairs" I might be really challenged because I don't have the same level of knowledge and support - plus the competitive landscape will be very different.
