What is duplicate content and how can I avoid being penalized for it on my site?
My compony's site's home page was not specificly optimized to any location. Now, I am planning to optimize it to Boston, and create ten or so other landing pages for other locations we serve. If we made these new pages by copying the original Boston one and changing the location's name (s/Boston/Montreal/), would Google consider them as duplicate pages and penalize us? What is the best practice for this?
