We are currently discussing various options for implementing a blog engine or Content Managing System. We have a Ruby on Rails application, which gives us the option of using an existing gem, creating the blogging CMS from scratch, or use the Wordpress API to publish content and basically pull it to our domain's blog page.
I don't fully understand how the API will work. However, I believe we publish the blog posts using the Wordpress interface and it will be stored somewhere on a private/public Wordpress website. The API will allow us to pull the various blog posts through to be loaded on our company domain's blog page.
My question is, how will this affect SEO ranking? Is there anything our team should be specifically aware of?
