Google Friendly VS Goole Non-Friendly Links

[GameOver]

I have decided to make this thread because it would be a useful resource to members, feel free to correct mistakes and add new info:

Google Friendly:

Do-follow blogs
Link Exchange
Free directories
Business directories

Google Non-Friendly:

Paid Links
Bid for Position
Link Farms

One-way links are good too from related sites) Not exchange

You can also have some article directories

Paid links can be google friendly, even very friendly. Just if google doesnt find them.
