Welcome to the Q&A Forum

I've read a lot of stuff and I can't get a good answer about this. Now I'm reading Wordpress 3 - Search Engine Optimization, and the writer says that less outbound dofollow links you have, better for you. What is the best practice in this subject? Should I really nofollow more than 80% of all my outbound links? Thank you.

Hi, I've a relative good ranking for a specific keyword in google.com (english queries (hl=en)), but searching for the same keyword in google.com.br (Brazilian Portuguese (hl=pt-BR)), my rank for that keyword is far worst. The question is: I need to do something specific to rank in google.com.br (hl=pt-BR)? I'm doing the regular link building. Creating some blogs, blogging for 10 days before droping my links, and creating link wheels the same way. The blogs I create to make links are written in Brazilian Portuguese, also, the blog that I'm trying to rank higher, is also written in Brazilian Portuguese. Sorry for the english, it's not my native language. Thanks
