Key to this working? Keep on blogging, any topic is ok, then tag those "computer repair Rochester MN" in those blogs. (insert your tags of course)
Then, start your blogs with "As you know, our computer repair store in Rochester, MN tells all of our clients that backing up your data is critical, even for your home computer"
Or, "when clients come in our computer repair store in Rochester MN with a virus removal, we often tell them that our antivirus protection plan is better because...."
then be sure to give that the H1, it's an option in Wordpress.
Blog the crap out of everything! lol If you can whip out a blog everyday, you will get faster results.
Google sometimes can give a page 1 on the spot (one of my clients asked me to help her, "waxing eagan mn" and she got on page 1 instantly, no competition. Sometimes takes consistency and a few weeks.

Good marketing results takes consistency, no matter what venue, including Google.
