I own about 30 sites on 5 different c-class ip addresses in these niches: - telecommunications - finance - home remodeling - health - automotive - tv - dating - computers I'm looking for webmasters to trade links: domainA --> domainB domainB --> domainC So it'll not be a link exchange. Google will see it as a 1-way link. We should place the links manually on content pages, they should have a PR of 1 or more, and less than 20 external links, no directory pages or pages only with links. Fore trading links with low PR pages it's much better to use Receivelinks (see link in my signature).
