Internal linking to subdomains
-
Hi *, I have a main site called example.org, and a lot of user generated pages to foo.example.org / bar.example.org and so on.
Most of those pages link back to example.org.
In example.org I have a page that links to all subdomains.
How can I optimize the pagerank of the list page? Should I add nofollow to subdomain sites to avoid passing link juice to those sites and keep normal linking from subdomain sites?
-
It's true that subdomains are not internal links. But if they are your subdomains they are trusted links.
When you place a link, your PR from that page will automatically flow to it. The only question you have to answer is, now that the link juice has been spent, do you want the link's target to benefit from the link and let your PR to flow to the page?
Can you share a context of where or why you think it would be beneficial to use nofollow on a link to one of your subdomains?
-
Yes, but from what I understood subdomains are not always considered internal links, that's why I asked.
I thought that having a lot of subdomains linking TO a page but not receiving any pagerank FROM that page would be beneficial to the listing page.
-
That is correct. PR from a nofollowed link does not flow to the target page. It does not flow anywhere and dies on the existing page.
-
Will you please clarify " Your page rank flows TO the link whether it is followed or not". I thought that if we add rel=nofollow, the pagerank does not flows to the target page.
-
As a rule, never add "nofollow" to internal links. Your page rank flows TO the link whether it is followed or not. When you add the "nofollow" tag, you stop the PR from flowing FROM the link and it simply dies.

Broken URL Links
Hi everyone, I have a question regarding broken URL links on my website. Late last year I move my site from an old platform to Shopify, and now have broken URL links giving out 4xx errors. When I look at Moz Pro>Campaigns>Insights>links, I can see the top broken URL links, however there is a difference if copy & paste URL directly from Moz Pro and by Export CSV file. For example below, If I copy and paste links direct from Moz Pro, it has the “http://” in front as below: http://www.thehairhub.com.au/WebRoot/ecshared01/Shops/thehairhub/57F3/1D8F/D244/C675/E27D/AC10/003F/35AD/manic-panic-colours.jpg But when I export the list of links as an CSV file, the http:// is removed. www.thehairhub.com.au/WebRoot/ecshared01/Shops/thehairhub/57F3/1D8F/D244/C675/E27D/AC10/003F/35AD/manic-panic-colours.jpg Another Example below: By copy & paste URL direct from Moz Pro

http://thehairhub.com.au/Shop-Brands/Vitafive-CPR/CPR-Rescue By export CSV file.
thehairhub.com.au/Shop-Brands/Vitafive-CPR/CPR-Rescue Which one do I use to enter into the “Redirect From” field in Shopify URL Redirects? Do I need to have the http:// in front of the URL? Or is it not required for redirects to work? Kind Regards, John Wall

How can I stop a tracking link from being indexed while still passing link equity?
I have a marketing campaign landing page and it uses a tracking URL to track clicks. The tracking links look something like this: http://this-is-the-origin-url.com/clkn/http/destination-url.com/ The problem is that Google is indexing these links as pages in the SERPs. Of course when they get indexed and then clicked, they show a 400 error because the /clkn/ link doesn't represent an actual page with content on it. The tracking link is set up to instantly 301 redirect to http://destination-url.com. Right now my dev team has blocked these links from crawlers by adding Disallow: /clkn/ in the robots.txt file, however, this blocks the flow of link equity to the destination page. How can I stop these links from being indexed without blocking the flow of link equity to the destination URL?

Can you be penalised in Google for excessive internal keyword linking?
I have an online shop and 3 blogs (with different topics) all set up on sub-domains (for security reasons, don't want Word Press installed in the same hosting space as my shop in case one gets hacked). I have been on the front page of Google for a keyword, lets say 'widgets' for months now. I have been writing blogs about 'widgets', probably about 1/4 of all my blog posts are linking to the 'widgets' page in my shop. I write maybe 1-2 blogs a week, so it's not excessive. This morning I have woken to fine that the widgets page in my shop has vanished from Google's index. So typing in 'widgets' brings up nothing. It hasn't dropped in the rankings, it's just vanished. A few weeks ago I ranked 3 or 4. Then I dropped to about 6. A couple of days ago, i jumped back up to 5 and now it's vanished. If you type in 'buy widgets', or 'widgets online' or 'widgets australia', I have the #1 spot for all those, but for 'widgets', I just don't exist anymore. Could I have been penalised for writing too many posts and keyword linking internally? They're not keyword stuffed and they're well written. I just don't understand what's happened. Right now I"m freaking out about blogging and putting internal links on my website.

Links from the same server has value or not
Hi Guys, Sometime ago one of the SEO experts said to me if I get links from the same IP address, Google doesn't count them as with much value. For an example, I am a web devleoper and I host all my clients websites on one server and link them back to me. Im wondering whether those links have any value when it comes to seo or should I consider getting different hosting providers? Regards Uds

Google Links
I am assuming that the list presented by Google Webmaster tools (TRAFFIC | Links To Your Site) is the one that will actually be used by Google for indexing ? There seem to be quite a few links that there that should not be there. ie Assumed NOFOLLOW links. Am I working under an incorrect assumption that all links in webmaster tools are actually followed ?

Subdomain for a blog
My client has a site hosted with a company that allows very little customization including I am unable to add a blog to the site. As he has a fair amount of time & money invested in the site, he is reluctant to start over. So my question is this. His blog is currently hosted off site, would it benefit him if I had them add a cname or a record to show his blog at blog.mydomain.com? Or does Google recognize that it is still a separate site and treat it as such? Finally does it matter how they set it up cname, a record or redirect? This is definitely not my area of expertise (if that is not already obvious from the question!). Thanks for your help! Matthew

Internal file extension canonicalization
Ok no doubt this is straightforward, however seem to be finding to hard to find a simple answer; our websites' internal pages have the extension .html. Trying to the navigate to that internal url without the .html extension results in a 404. The question is; should a 401 be used to direct to the extension-less url to future proof? and should internal links direct to the extension-less url for the same reason? Hopefully that makes sense and apologies for what I believe is a straightforward answer;
