Welcome to the Q&A Forum

I have a local business and put additional city names (7 of them) into the main title page along with the biz description in order to expand into these areas. I included these same cities on 3 other pages in the site as well, along with the custom descriptions for these pages.  Is this overuse of city names in title pages? Will it negatively affect my rankings? What are the best ways to expand your marketing territory for a local biz? Thanks for any and all responses.
