What's the difference between follow and nofollow links?
-
I understand this may be a really dumb question and from my understanding there is a piece of code in some url's that tell search engines not to follow that link. I am interested in finding out what the purpose of nofollow links are and how they apply to search rankings.
Thanks for the help

Spiders from search engiines "crawl" the web by following a link from one page to another. Using a rel=nofollow HTML attribute on a link tells the search engine not to follw the link and crawl the page that the link points to.
Search engine rankings by sites like Google are based on the premise that the best content has the most links to it (this is a super over-simplification, I know). "nofollow" links aren't counted by Google when they assign value to the page being linked to.
Most often sites use "nofollow" to block links from user generated content that might be used to manipulate search engines. An example of this might be a blog that nofollows all the links in it's comments so that spammers don't show up and flood the comment section with links to sites they'd like to rank higher in google.

Basically, a link with rel="nofollow" will not pass link juice to that page.
The nofollow can be used to link to outside content without passing link juice, and is widely used in many sites with user generated content and profiles to prevent link spamming.

Backlinks from different TLD's impact
Hi MOZ'ers, I'm wondering what the impact of different TLD backlinks is for same language pages. For example: we're on a website that has a German national TLD .de. We're earning backlinks and they are coming from .de as well as .ch (Switzerland) or .at (Austria) pages. What would be more desirable, and how big would you consider the difference? Looking forward to hearing your responses 🙂 Justen

Nofollow links showing up in Google Search Console
If some nofollow links are showing up in Google Search Console, does that mean they are indeed passing link juice?

Nofollow affiliate links
I am setting up an affiliate program using software built in to my shop already (x-cart). The links generated by the software do not have the rel="nofollow" in them. I'm assuming they should have? When looking at Amazon, there must be millions of links out there pointing back to Amazon and all those links are followed back to them for link juice. Am I missing something? Surely best practice here is to re="nofollow" so you're not seen to be manipulating Google PageRank?

Links from PRWeb press release violate Google's quality guidelines?
My site has had a manual action performed on it by Google indicating that I have inbound links that fall outside of their quality guidelines. I did my own research, found what I thought was the issue, had the links removed and requested reconsideration. Google's response surprised me in that they highlighted two specific pages with links that were the direct result of valid press releases and a publisher picking up our release off a wire service. Has anyone else seen this occur? Anyone had a case successfully reconsidered? I realize that I don't need to do anything at all as the manual action is in effect and will stay that way, discounting those links, but I would rather a) not have any manual action against my site and b) know for the future so this doesn't happen again. Also, is this applicable for guest blog posts, which effectively create the same type of backlinks? Thanks

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 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,

How important are different class c subnets and ip's
We're thinking of launching several blogs in our niche and 'building them up' organically, and then linking naturally from them to our sites (very conservatively). I was wondering if we should buy entirely separate hosting for these blogs and how important are separate ip addresses and class c subnets (shown on majestic SEO tools for instance). Is it possible to create a set of authoritative blogs in a niche and have them be a little 'neighborhood' within the same shared hosting provider (obv similiar class c or even same ip).

How does Google interpret articles or prepositions in languages where it's attached to the (key)word?
Hi, All! This is for any foreign language SEOs where articles or prepostitions such as "the" "to" "in" or anything else are actually part of the word they are modifying and not a separate word, as in English: How does Google understand those words on-page and in anchor text? If you want to optimize for the word "house", and your content/anchor text says "the house" or "in the house" (again, all one word) - what does Google count that as? Does it count toward "house"? Does it count toward "in the house" only? Does it count toward "house" but not as much as if you had just put "house"? I end up sometimes writing slightly grammatically-off content because I want to optimize for the keyphrase - but is that necessary? Obviously different languages might be different, but you can probably project a little from one to the others. Thanks in advance!
