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.

Internal Linking - Post links vs Side Bar Links behaving differently
Hi, I have a question regarding the internal linking behavior. My website is www.hindimeaning.com which is approx 3 years old. I have approx 450 posts. Now i have a widget on right sidebar "Popular posts". A widget below my posts "Related Posts". And a simple html CSS menu above the posts (I removed menu around 6 month before so currently it will not show.) I crawled my site with moz crawler (same are the result from google crawler as well) and it shows menus links as internal links. While sidebar widget "Popular posts" and "Related Posts" are not showing as internal links. If we talk theoretically what i learn till now is "every link on a page behaves as internal link". Then why the widget links are not showing as internal links. Thanks, Mahesh Kumar

Nasty links
Hi My first q on here (hoorah!), and it's about links (boo!). I've got what appears to be a handful (but worryingly, increasing in number) of links pointing to my site like this: http://condos.mrgulffront.com/florida-condos-for-sale/320-scenic-gulf-drive-miramar-beach-fl-32550-mls-567591/ I've made contact with the sites concerned, and had only one positive response who flatly denied all knowledge of it. The issue (as far as I can see) is that as in the above example the links (on the bottom right in the grey box) are forever changing so not always visible. Can anyone offer any guidance as to these kinds of nasty links.... I'm right at the v beginning on this "path of seo understanding" so please don't assume prior knowledge! Thanks in advance.... tom

Best SEO practice to redirect affiliate link
Hello, I got an affiliate program on my website, that redirects the affiliate link to the main site like: site.com/ads/aff_code/ -> site.com/ (The redirect is done using a 301 status code.) On the redirect process the site stores a cookie to track the affiliate sale. Will Google and others SE follow this permanent redirect, transferring the relevance of this affiliate link to my main site? In other words, if an affiliate does something wrong (like spams), does the bad reputation will be transferred to my main site? Is there a better way to do that from a SEO standpoint? Thanks,

Link Exchange
Hi everyone, I just started working for a client in a new niche. After reviewing the backlink profiles of his competitors I can see that the top sites are using a ton of link exchanges. They are from really spammy sites too. The kind that will link to anyone that provides a link back. Anyone else seeing much of this?

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,

EBay listing links SEO value?
Hi guys, Our website has an eBay widget which lots of eBay users put on their listings. We are thinking of using that as a way to get links from eBay listings. However, since most eBay listings will disappear after 90 days, is this worth doing and also will Google count those links? Many thanks David
