The question often arises, “Can you compete both in local search and global search?” Of course, the answer is “Absolutely.”
The key is to claim your Google Places and Bing Local listings while continuing to optimize your website for organic search. Where you want to dominate in local search is on Google Maps and Bing Maps. To do that, you want to claim those listings. Be sure to include address, phone number, hours, and other locally identifying information in those listings.
With global organic search, you just do all the normal things you would do on your website and off site to rank your web pages. I’d also encourage you to open up a Google+ account.
On Google+, you want to link to your website’s home page. When you set up your Google+ account, you have a Links section. That’s a good place to link to all of your websites. Just link to each website once. And if you are a contributor to third-party websites or blogs, and you should be, then list those links in the Contributor section. Ask the owner of those sites to follow the Google guidelines for Authorship.
You can rank locally and globally. You just have to focus your efforts on organic search for your website and make your local search efforts focused through Maps.
