Does link exchange really work?

[Asia]

Hello,

Does link exchange really work? Lets say I purchase 1000 link backs, does it increase my serp significantly?

Might do. Might get you banned, too. How many of those 1000 links have to be 'bad neighborhood' to get your site into that neighborhood?

Not many. Does the linkseller care? Nope.

There's much better ways to spend your money.
Like buying real estate on Mars ;)

Generally they don't help. Lot of times you hardly get traffic from them to begin with. I've link traded with some high rank sites that have 5PR and I hardly see any traffic from them. Most of my traffic comes from word of mouth an search engines.
