Link building w/ Multiple links in 1 post vs. multiple posts with 1 link
When you're link building on blog networks or however you're doing it, would you say that it's best to build multiple links (2-5) in one blog post to the same domain, or to build multiple blog posts with 1 link. From what I understand, most decent blog networks have diversified IP addresses or C-IP addresses, so I would think that multiple posts with 1 link would be best? I could be wrong.
For 3 months or so, I've done posts with 2-3 links to the same domain in 1 post, but over the past month, I've tried doing 1 link/post but with more posts. I've found #2 to be more effective, but it's hard to measure as the first 3 months of work may have been kicking in while I was doing multiple unique blog posts.
Any Thoughts?
