There's something I should clear out as I get asked about it a lot by PM's. All the content in the sites we provide is unique and written by native Spanish speakers exclusively. We do NOT use translation software, as that the results from it are poor at best.
NEVER use translation software to put content in your sites, specially with Spanish, as it can produce text that has no meaning, different meaning or even insulting meaning. This is a sure fire way to get your site penalized by Google and your visitors offended.
