Welcome to the Q&A Forum

For a business that's very local-focused, it's a good idea to use location keywords in your title tag and occasionally use them in copy on the page. So your title tag might be something like Bob's Computer Fix-It Shop - Alexandria Computer Repair. Then your homepage might claim "We are the most awesome computer repair experts in Alexandria, VA." Keep in mind, however, that searches with local intent often have the organic results buried underneath the Google local results. Make sure your Google+ page is amazing and encourage customers to review you on Google+.
