I mean, I want to seo my site, so I know that I have to start a link building campain, so… can I link my site to other websites that have different language, like german or spanish when my site is in english.
thank you so much for your time

For building backlinks I look for sites that deal in the same topics/products and have a good Google PageRank. If it is a quality website with good content, that matters more to me than the language of the site.
