For mee it works well. I usually exchange links with similar sites. I mean if I have an entertainment site I exchange link with entertainment only and it works.
Link exchanges and blog links are the only way how I build my link campaign for my new websites. I have received great page rank boosts from high PR link exchange partners so yes it does work.
Yes, Link exchange really works, especially if link with higher PR the better. but beware of those who links to you. They must be related to your site. 100% relevant links sites excellent link building strategy....
Link exchanges still work if done in effective manner. Two-way link exchanges are kind of history now and have very less advantage as compared to three-way link exchanges, that way all sites involved will get advantage for link building.
Link Exchange works as long as the site that you're linked to is related and quality site. But we have to minimize it as stated at Google Webmaster's Guidelines.
Reciprocal links work if you link with authority and relevant sites in your niche. For PR building - it still has value although not as good as natural and one-way links
Well they have worked for me. i have personally corresponded to website owners, for link exchange who have a similar PR as mine, and they seem effective to me!
Do links from your website to others hurt you or not ... I have read in a few areas that linking to too many external sites looks bad to google is this true or just there to scare me
