I'm sure lots of other people have sites which are german, french, protugese, spanish, etc... and one of the hardest parts of dominating positions in these specific google engines is that in other countries marketers don't have nearly as many backlink resources available as english sites do. No one could give me an accurate answer to if a non english site would benefit from only english links. Well my friends, since no one gave me an accurate answer and since I needed to rank in country specific google search engines I tested it out. I have two sites, one french and one brazilian both are four months old and both are ranking #1 for their main keyword with the help of only english links. So it seems it works my friends Well, at least it's working so far. Don't know if I'm gonna get google slapped in a month or two.
