Welcome to the Q&A Forum

Hi Call Ring Talk, You have already received such awesome and helpful replies from the community, I will only add a bit here, some of which will be a summary of what others have written. Local rankings depend on a ton of different factors. Where you have a physical location, your best bet is typically to pursue local rankings. If you are a Service Area Business (SAB) you must pursue organic rankings for your service cities. Per your original question, the development of city landing pages on your website is one of the best tactics for achieving organic rankings for cities where you serve but where you have no physical location. For more information on the topic of city landing pages, I have been told that this piece has been really helpful to a ton of people: The Nitty Gritty of City Landing Pages If the whole concept of Local SEO is new to you, I recommend that you read through all of the articles on GetListed.org, which is a MOZ website. Here is the link to the Learning Center: https://getlisted.org/static/resources/ I further recommend that you follow Local Search Godfather, Mike Blumenthal, on a regular basis: blumenthals.com/blog And that you review the 2012 Local Search Ranking Factors report, though many things have changed in the past year. For many years running, this has been the premiere Local SEO industry survey: http://www.davidmihm.com/local-search-ranking-factors.shtml One of the keys to successful Local SEO for any business is staying on top of the nearly-constant changes that happen in this area of marketing. Keep current and it will serve your business well!

Although both pages are very similar sans the logo color and some verbiage, if we do the rel canonical from GoCentrix->CallRingTalk.com then CallRingTalk.com will be the preferred site for indexing? ** Yes. You can also add rel canonical to it self on  CallRingTalk.com. Lastly, will having had the duplicate content for some time now have any sort of lasting effect on our potential ranking once we implement the canonicalization? ** No, you are more then safe. This rel canonical will only help google understand what is your preferred version and it will display it accordantly. Overall the only downside of duplicate content is that Google might show in serps the version that is teh secondary as importance in your opinion - but there is no algorithmic or manual filter / penalty for this even if you don't implement rel canonical. Hope it helps.
