If you want to be safe

just trade links with sites similiar to yours

Google has special detectors built in that can tell when you just link to increase your search engine rankings so must think really hard when you are adding the links for other reasons when you are adding them

did you ever see the movie firefox , when clint eastwood had to think in russian in order to fly the plane its the same thing

I'm joking of course

just trade links with sites that similiar to your to be safe
