Welcome to the Q&A Forum

What if my translator first use a translating software but then adjusts the text for specific language and locality stuff?

It would appear you are trying to become the Brazilian eHow. Given that they are not favorites of Google, etc. I would say be careful. You are already starting off using some questionable methodologies - Paid links as a starter. As to the sidebar links, they are discounted, so you need to stay after it for real quality links. If you dont mind spending a few dollars, Yahoo Directory ($295) could be a good direction. I would also insure that you are tight on local and are on every citation site you can find. There is a good list: http://www.seomoz.org/directories and here is a great Cyrus Shepard post around web directories and linking.  Obviously, your biggest challenge will be to have content around How To. So, you have your work cut out for you. Hope this helps a bit,
