Mum ... I never really looked this as a problem until the last Google updates.
So if I got it properly:
- Keeping one link on the home may not hurt my website (now)
- Keeping the footer link on all website would be the last thing to do
- Keeping the link in nofollow can bring me some new customers (now) and penalize my site soon
I think I'm going for the nofollow option now.
What do you think ?
