Welcome to the Q&A Forum

Teresita, The first thing I looked at was the approximate volume of content indexed in Google for each domain. site:http://radiocolombiainternacional.com/web/ shows 403 results. site:http://radiocolombiainternacional.com/ shows 470 results. site:http://radiocolombia.com.co/ shows 127 results. While the "site:domain" check only offers an approximation, its a starting point to evaluate how Google sees each site. An important question to ask then is "What is the real, actual count of pages for each domain?" If it's on the higher end (close to 400 pages) for both radiocolombiainternacional and radiocolombia then Google APPEARS to be giving much more trust to content on radiocolombiainternacional. If that is true, that's what I would go with  - its an indicator that radiocolombiainternacional has a stronger foundation in Google's perspective. If you have site analytics available for both, that's another path to dive into to get even more information and data that may or may not support that concept though.  Just because a site has more pages indexed in Google doesn't itself mean that site is getting more quality traffic. Another consideration is inbound "follow" links.  What is the total count pointing to each? Using OpenSiteExplorer, radiocolombia.com.co has more inbound links, and what appears to be a stronger internal linking structure as well.  So that conflicts with the Google page indexed count.  Except neither site has very many inbound links at all (a serious challenge that needs to be addressed whichever site you end up with). Because of these factors, I'd need to see more information about each site regarding inbound links, actual page count, etc. Since you say they've got the exact same content, I assume they're on the same programming framework so the technical factor is less of a comparison issue. When I visit the home page for each, they do look identical, so that reinforces the notion that technical factors are going to need to be considered.
