I have read quite often recently that all backlinks except high quality backlinks (some times even them) are dead. I have a hard time to believe this since all my concurrents have a lot of spam-links. Actually like 90% of their links are from obvious linkfarms... But they still rank! My theory is that Google now put more weight on how fast a certain amount of links are created. If I'm right that should mean that you are safe if you create like 200 links a week (instead of 2000 in 4 days). What do you guys think? Any thoughts on this?
