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.

Should I disavow these links?
Hi all, I have a ski website that I am currently performing a toxic backlink audit on. I have noted that a lot of the links being flagged as toxic/spammy by the tool I am using seem to be the same/similar sites with different URLs. The sites are vaguely related to skiing (relating to helicopter travel options for travelling to ski resorts) but it is concerning me that there are so many of them and they are being flagged as so toxic.

Do you think it is worth disavowing these? Or contacting the owner to ask them to remove the link? I have included an example of some of the links below. https://www.cannes-helicopters.co.uk/index.php?menuopen=21&showcontent=5
https://nice-helicopter.co.uk/index.php?menuopen=21&showcontent=5
https://monaco-helicopter.co.uk/index.php?menuopen=21&showcontent=5 Slightly different site but same favicon icon:

When conducting a link building strategy does it matter the country the link is from?
We are a UK business and if we have links mostly from US based blogs and websites does this penalise us. The links are from relevant websites and topics. Should we be focusing on .co.uk sites

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. Our digital distribution network includes: The LA Times; The Milwaukee Journal Sentinel (JS Online); Las Vegas Review Journal; Hearst media sites for the San Francisco Chronicle, Houston Chronicle and Connecticut Post and others; local TV news affiliate sites from ABC, CBS, FOX and others; and hundreds more trusted sites.

Does the ratio of external nofollow links to external "do follow" links matter in terms of SERPs ranking?
My site has an external link nofollow:dofollow ratio of approximately 1:1 That is, there are about as many nofollow external links as "do follow" external links. I have an impression that the ratio of no-follow to "do follow" links is a factor in the way that our website shows up in SERPs. I have the impression from reading a variety of sources, and from looking at Seomoz, that calculate "trust" factors as if they mattered (in SERPs), that seem to value a relatively low nofollow:dofollow ratio. Am I correct about that? Thanks,
