Follow or nofollow to subdomain
-
Hi,
I run a hotel booking site and the booking engine is setup on a subdomain.
The subdomain is disabled from being indexed in robots.txtShould the links from the main domain have a nofollow to the subdomain? What are you thoughts?
Thanks!

Yeah, internally, "nofollow" still dilutes PageRank, so it doesn't really have a big impact. Practically speaking, I don't think there would be much difference. The links have a customer-facing purposes, I assume, and you just don't want the end result indexed. That should be fine. The only advantage to nofollow might be that it would waste a little less crawl bandwidth (instead of bots visiting the page and then seeing it's blocked, they wouldn't bother). I've tried it both ways in the past (after Google changed the PR-sculpting rules), and could never really measure much difference.

Thanks for your reply.
An article I read recently suggested that using nofollow on links on the same website may not be a good idea as "if the website doesn't trust its own pages by having a nofollow, then why would Google want to put trust in it." Does this make sense? Would a subdomain be considered as a completely different site?
My other concern is using nofollow extensively may raise a flag to Google as a site that is heavily seo optimized or tries to manipulate its linking strategy.
Any more thoughts? The website is done 100% for users. All I am looking for is the best practice to follow to maximize the seo efforts in this area.

"diluting your authority by having dofollow links" I thought it was not possible to link sclupt in this way, I'm I missing something?
My understanding is that all no follow does is not pass authority and does not help retain authority ( basicly it just throws it out the window the authority it would have passed to that link)
-
There is no point diluting your authority by having dofollow links to the subdomain if it isn't going to rank, so by all means "nofollow" the links.

Should I add no-follow tags to my widget links?
Matt Cutts recommended in a video in 2013 to add rel="nofollow" on widget links that link back to your website. Some background of my company: We're a software company for website chat. There's a 'powered by' link in our widgets that links back from our users' websites to our website. Currently these are all follow links. I checked out the links of our competitors, and it seems none of them have no follow on their widget backlinks. This, together with the fact that the video is quite old and information on this issue rather scarce, makes me doubt whether we should change our widget backlinks to no follow. Does anyone have thoughts on this?

The Great Subdomain vs. Subfolder Debate, what is the best answer?
Recently one of my clients was hesitant to move their new store locator pages to a subdomain. They have some SEO knowledge and cited the whiteboard Friday article at https://moz.com/blog/subdomains-vs-subfolders-rel-canonical-vs-301-how-to-structure-links-optimally-for-seo-whiteboard-friday. While it is very possible that Rand Fiskin has a valid point I felt hesitant to let this be the final verdict. John Mueller from Google Webmaster Central claims that Google is indifferent towards subdomains vs subfolders. https://www.youtube.com/watch?v=9h1t5fs5VcI#t=50 Also this SEO disagreed with Rand Fiskin’s post about using sub folders instead of sub domains. He claims that Rand Fiskin ran only 3 experiments over 2 years, while he has tested multiple subdomain vs subfolder experiments over 10 years and observed no difference. http://www.seo-theory.com/2015/02/06/subdomains-vs-subfolders-what-are-the-facts-on-rankings/ Here is another post from the Website Magazine. They too believe that there is no SEO benefits of a subdomain vs subfolder infrastructure. Proper SEO and infrastructure is what is most important. http://www.websitemagazine.com/content/blogs/posts/archive/2015/03/10/seo-inquiry-subdomains-subdirectories.aspx Again Rand might be right, but I rather provide a recommendation to my client based on an authoritative source such as a Google engineer like John Mueller. Does anybody else have any thoughts and/or insight about this?

Blog On Subdomain - Do backlinks to the blog posts on Subdomain count as links for main site?
I want to put blog on my site. The IT department is asking that I use a subdomain (myblog.mysite.com) instead of a subfolder (mysite.com/myblog). I am worried b/c it was my understanding that any links I get to my blog posts (if on subdomain) will not count toward the main site (search engines would view almost as other website). The main purpose of this blog is to attract backlinks. That is why I prefer the subfolder location for the Blog. Can anyone tell me if I am thinking about this right? Another solution I am being offered is to use a reverse proxy. Thoughts? Thank you for your time.

Accidently added a nofollow, noindex tag and then...
Hey guys, My first post here and ironically highlights a ridiculously stupid mistake! Ok, here's the deal... I started building links to one of my new page on a fairly good, old site (DA = >35). Before starting to build links, I added fresh new content, and while doing that, I accidentally added a "nofollow" and "noindex" tag to the page! Guess what, google DID de-index the page ! So the questions is (and YES, I did change the meta tags): Will google re-index the page with some good linking? Will it treat the page as a new, fresh page even though it was present for over a year? I had already started link building to that page, and now technically the links are pointing to a page that does not exist in the index, so once it does get re-indexed, will Google FLAG it as having too many links? Would I be ranking it as a new page? Will its previous ranking (for very few keywords) will come back? Thanks and Regards, Amod

Duplicate internal links on page, any benefit to nofollow
Link spam is naturally a hot topic amongst SEO's, particularly post Penguin. While digging around forums etc, I watched a video blog from Matt Cutts posted a while ago that suggests that Google only pays attention to the first instance of a link on the page As most websites will have multiple instances of a links (header, footer and body text), is it beneficial to nofollow the additional instances of the link? Also as the first instance of a link will in most cases be within the header nav, does that then make the content link text critical or can good on page optimisation be pulled from the title attribute? I would appreciate the experiences and thoughts Mozzers thoughts on this thanks in advance!

How Google treat internal links with rel="nofollow"?
Today, I was reading about NoFollow on Wikipedia. Following statement is over my head and not able to understand with proper manner. "Google states that their engine takes "nofollow" literally and does not "follow" the link at all. However, experiments conducted by SEOs show conflicting results. These studies reveal that Google does follow the link, but does not index the linked-to page, unless it was in Google's index already for other reasons (such as other, non-nofollow links that point to the page)." It's all about indexing and ranking for specific keywords for hyperlink text during external links. I aware about that section. It may not generate in relevant result during any keyword on Google web search. But, what about internal links? I have defined rel="nofollow" attribute on too many internal links. I have archive blog post of Randfish with same subject. I read following question over there. Q. Does Google recommend the use of nofollow internally as a positive method for controlling the flow of internal link love? [In 2007] A: Yes – webmasters can feel free to use nofollow internally to help tell Googlebot which pages they want to receive link juice from other pages

(Matt's precise words were: The nofollow attribute is just a mechanism that gives webmasters the ability to modify PageRank flow at link-level granularity. Plenty of other mechanisms would also work (e.g. a link through a page that is robot.txt'ed out), but nofollow on individual links is simpler for some folks to use. There's no stigma to using nofollow, even on your own internal links; for Google, nofollow'ed links are dropped out of our link graph; we don't even use such links for discovery. By the way, the nofollow meta tag does that same thing, but at a page level.) Matt has given excellent answer on following question. [In 2011] Q: Should internal links use rel="nofollow"? A:Matt said: "I don't know how to make it more concrete than that." I use nofollow for each internal link that points to an internal page that has the meta name="robots" content="noindex" tag. Why should I waste Googlebot's ressources and those of my server if in the end the target must not be indexed? As far as I can say and since years, this does not cause any problems at all. For internal page anchors (links with the hash mark in front like "#top", the answer is "no", of course. I am still using nofollow attributes on my website. So, what is current trend? Will it require to use nofollow attribute for internal pages?0
