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.

If I nofollow outbound external links to minimize link juice loss > is it a good/bad thing?
OK, imagine you have a blog, and you want to make each blog post authoritative so you link out to authority relevant websites for reference. In this case it is two external links per blog post, one to an authority website for reference and one to flickr for photo credit. And one internal link to another part of the website like the buy-now page or a related internal blog post. Now tell me if this is a good or bad idea. What if you nofollow the external links and leave the internal link untouched so all internal links are dofollow. The thinking is this minimizes loss of link juice from external links and keeps it flowing through internal links to pages within the website. Would it be a good idea to lay off the nofollow tag and leave all as do follow? or would this be a good way to link out to authority sites but keep the link juice internal? Your thoughts are welcome. Thanks.

Nofollow Outbound Links on Listings from Travel Sites?
We oversee a variety of regional, county, and town level tourism websites, each with hundreds (or even thousands) of places/businesses represented with individual pages. Each page contains a link back to the place's main web presence if available. My fear is that a large portion of these linked to sites are low quality, and may even be spammy. With our budgets there is no way to sort through them and assign nofollows as needed. There are also a number of broken links that we try to stay on top of but at times some slip through due to the sheer number of pages. I am thinking about adding a nofollow to these outbound links across the board. This would not be all outbound links on the website, just the website links on the listing pages. I would love to know peoples thoughts on this.

How to handle a blog subdomain on the main sitemap and robots file?
Hi, I have some confusion about how our blog subdomain is handled in our sitemap. We have our main website, example.com, and our blog, blog.example.com. Should we list the blog subdomain URL in our main sitemap? In other words, is listing a subdomain allowed in the root sitemap? What does the final structure look like in terms of the sitemap and robots file? Specifically: **example.com/sitemap.xml ** would I include a link to our blog subdomain (blog.example.com)? example.com/robots.xml would I include a link to BOTH our main sitemap and blog sitemap? blog.example.com/sitemap.xml would I include a link to our main website URL (even though it's not a subdomain)? blog.example.com/robots.xml does a subdomain need its own robots file? I'm a technical SEO and understand the mechanics of much of on-page SEO.... but for some reason I never found an answer to this specific question and I am wondering how the pros do it. I appreciate your help with this.

Moving blog to a subdomain, how can I help it rank?
Hi all, We recently moved our blog to a sub-domain where it is hosted on Wordpress. It was very recent and we're actively working on the SEO, but any pointers on getting the subdomain to rank higher than the old blog posts would be terrific. Thanks!

Should I NOFOLLOW my "Add To Cart" buttons?
Hello and Merry Christmass Should I NOFOLLOW my "Add To Cart" buttons? My e-commerce site has hundreds of products. Content wise, there is no real value to the reader on that page (besides for some testimonials and "why here" sentences). So it is not a page you'd want / expect to find in the SERPs. Also, with hundreds of links pointing to this page it would be "stronger" than other important pages which doesn't make sense. Last but not least, if I have limited time that the bots are on my site, why keep sending them to a non important page. This is why I am leaning to nofollowing the "add to cart" buttons and looking for reinforcements. Thanks

How do I list the subdomains of a domain?
Hi Mozers, I am trying to find what subdomains are currently active on a particular domain. Is there a way to get a list of this information? The only way I could think of doing it is to run a google search on; site:example.com -site:www.example.com The only issues with this approach is that a majority of the indexed pages exist on the non-www domain and I still have thousands of pages in the results (mainly from the non-www). Is there another way to do it in Google? OR is there a server admin online tool that will tell me this information? Cheers, Dan

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!

NOINDEX or NOINDEX,FOLLOW
Currently we employ this tag on pages we want to keep out of the index but want link juice to flow through them: <META NAME="ROBOTS" CONTENT="NOINDEX"> Is the tag above the same as: <META NAME="ROBOTS" CONTENT="NOINDEX,FOLLOW"> Or should we be specifying the "FOLLOW" in our tag?
