What impact does multiple links from the same c-block have on SEO?
-
Recently there's been a move made in my company to only allow backlinks from websites on different c-block IP addresses. The most links we have from one c-block is 15. There is a wide variety of other IP addresses linking to our site as well. My question is - do we need to be so restrictive with using websites from the same c-block as long as the neighbourhood is good and we're not linking sites with full identical IPs (matching d-block as well)?
-
Thanks James, I just wanted to clarify as it was not clear you were making that distinction in your initial answer.
-
We're not even talking identical IPs in this situation, we're talking matching c-block but unique IP. Would your answer still be the same?
-
If you take links from c class ip sites which are handled from the same company/owner, then it is harmful. if owner/company is different, then no problem.

Can affiliate links benefit or hurt my seo?
I have just signed up with a company to do affiliate marketing for my site. I am now in the process of reaching out to publishers and seeing who will publish my link on their site. Is there any benefit in terms of seo for having these links, and can there be any potential downside to these links as well?

Mat Release SEO Impact
How do Mat Releases affect SEO? Does google recognize that your are syndicating duplicate content even if the content is being syndicated across top media outlets? Do these back links still carry any authority or can we even be penalized for the duplicate content? I came across mat releases here: http://matrelease.com/ An example of article syndication outlets: Guaranteed Placement on 800+ Media Sites. Generate guaranteed article placement on more than 800 respected online media outlets.

A link with "return false"- OSE sees as a No Followed Link
Hello, I couldn't find a clear answer to the impact on SEO for a link written in this way: [" class="expert_info" onclick="window.open(this.href);return false;">](w</span>ww.yourwebsite.com<span style=) [Does the "return false" act as a "no follow"? I came across this in our link data in Open Site Explorer which lists these links all as "no follows." However, an engineer I spoke to said that it shouldn't impact search engine behavior. Any ideas? Thank you in advance! -Sarah K.](w</span>ww.yourwebsite.com<span style=)

Does blocking domains help remove bad links?
I have affiliate websites that are harming for one of 2 reasons: 1. They are on adult websites (and I don't want to be in a bad neighborhood) or 2. They are using a Frameset (so their content appears identical to mine and I am getting "credit" for all their junk links) I cannot get these websites to remove our links so I have blocked their IPs on our production firewall. Is this an effective method or should I do something else with these links?

Link Frequency
I understand that good link building is all about the quality of the link / the anchor text attached to it. But, what about frequency? Should I build until I can't build anymore? or create a plan to submit links to a certain # of sites per week/month?
