Welcome to the Q&A Forum

I have an e-commerce site that was optimized for local results. We’ve been receiving traffic from all over the nation so recently we've decided to optimize the site for a more national audience by removing the local business indicators. I have below a list of things that I’ve done, I’m contemplating doing and other various questions. One note I want to make is that we offer installation services – which we would still like to rank locally for. I have done the following: Remove [city] from all of the title tags (except for the installation pages) Removed NAP (name, address, ph#) from site wide footer – I’m not sure if I should have done this. Inserted NAP at the bottom of the body content of the installation pages Questions Right now my installation pages are located in a sub-folder (ex: www.mydomain.com/installation-services).  Should I create a sub-domain for installations (ex: city.mydomain.com/installation-services)? My thoughts are that it would make that sub-domain all about our installation services while keeping our root domain focused on our products and not dilute it with installations. However, this sub-domain will have less juicy juice. What should I do with our G+ business page? In the back end of the business G+, there are boxes I can check for “my business has service areas where I visit my customers at their location” and “I serve customers at my business address.” If checked, will these make my site less likely to rank Nationally? We DO have a storefront and we DO visit people to do installations, so I would like these to be checked but not if it hurts my national rankings. There are local “7 pack” results for my main keywords and their installations. So, I would want my root domain to show up locally for “widgets in [city]” and my sub-domain to show up for “widget installation in [city]". Is it against Google’s TOS to create another G+ business page for the sub-domain? Is this even possible? Do I even need to do this or will Google know that I have a sub-domain all about installation and have my site show up in the local results? Is there anything in GWT that I need to make sure to have done? I put the geographic target to United States. Is there anything else? Of course, there is always the option of creating a new domain and optimize it for the installations. Any other suggestions would be greatly appreciated. Thank you.

I have two different websites. One of them is one of the most authoritative e-commerce websites in its niche. I own forums, installation resource websites and various other sites that provide excellent user information and customer interactions. There is another e-commerce website that I own which is very young and not as authoritative. I am about to start building it out like I did for my other site. My question is about whether I should link my G+ profile and become a "contributor/author" to the new e-commerce site(s) or if I should have someone else in the company be the "face" of this website. Since they're in two completely different niche's, I didn't know if it will give mixed signals to Google if my G+ profile is all about niche A, and then I start throwing in rel=author and being a contributor to other sites that have nothing to do with the original niche. Should I create another G+ profile to contribute to all of the guest posting & 2nd tier site creation for the new niche site or just use the one I have now for the time being?
