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.

Effects of a bad link linking to a image
i am getting a lot of links from wallpapers sites.. One person has created 1000's of similar sites that are linking back to my images. My guess is images do not pass link value positive or negative. But I am not sure what the potential effects would be. Does anyone know who linking to images might effect SEO especially when there coming from horribly low quality auto generated sites.

Should I disavow these links?
Hi all, I have a site that is a year old, we have been building backlinks organically - probably around 50 or so - then almost overnight we had100s of spammy links. Screenshot here: https://ibb.co/cijiub My questions: Should I disavow these? What happens if I don't disavow these? Can I work out where they came from? If I disavow a few of them, is this a token offering to the Google Gods that will lower my risk of being penalised? Thank you. cijiub

Which Links to Disavow!
We just took over SEO for a new client who is being penalized for a bad link profile. They've asked Google to reconsider multiple times, and Google still claims that the links are bad. Because of this, and because I don't have direct access (logins, etc.) to what the former SEO did, I am considering using the disavow links tool. The most obvious links to disavow are a group of almost 1000 links that come from the same forum. However, when viewing the links on this forum they actually seem natural. People are reviewing the product (ipod cases), both negatively and positively. While this could have been an SEO tactic for link building, I don't want to disavow these links if they're not the problem, even though this domain is the source of almost all the low-quality links. Another site that has more than 200 links is Askives. Do any of you have experience with links from Askives, or removing these links? Thanks again!

Remove Unatural Links by SEO Co.
The SEO firm we hired built 2797 links with 123 domain within two month period (March and April) when we don't know better. We received Google's warning on 3/28, and they didn't tell us anything but keep building. Well, that's history now. We learned our lesson. That's why we are a member of SEOmoz. The SEO firm is not too keen on helping us remove the link (we've discontinue the service) after one initial attempt to a few site with tons of links (performed by their Indian team). I've got advice from this Forum regarding link removal. The most suggestions we get is to remove it as many as possible and move on building good links. But, I am afraid such approach will take us years to come ahead as we are under staffed. I saw here that someone mentioned their link building firm wants to charge $10 for links removed. Based on that idea, I wonder if I should offer some monetary incentive? If so, what amount would make financial sense?

How best to link multiple related websites.
I have a handful of e-commerce websites that overlap each other some in the same niche. I have already heard that it would have been best to make just one website, but this is not practical for me. Our business model goes back to a time before the internet. We have relationships with manufacturers where they refer business to us because we brand web sites which will not switch customers to competing brands. Our agreements make it ok to link to other websites so long as we have branded websites that focus on the specific manufacturers. For SEO, what is the best way to link these sites? Site wide links in footers.? Single links at on homepages? One way links from the most powerful site? Some other method? We have been wrestling with this question for some time.
