Root-Domain vs Subdomain Linkbuilding
-
Hello Mozzers!
Couple of days ago I received a request to start optimizing a wordpress website, the domain itself has been around for around 10-12 years so it's it can be considered as one that has real history behind it. The page has been moved from HTML/FLASH to wordpress about 3 - 4 years ago and hasn't been any SEO maintenance on it. The site used to rank for first position with several keywords, but now understandably, it has greatly decreased.
My main question would be, that when I've checked the root domain's and the subdomain's metrics with MOZ Open Site Explorer, the sub domain (with "www.") showed a PA 40 and 90 external links while the root domain (without "www.") only has 27 PA and 6 External links.
I know that the 301 or server redirects only transfers about 90% of the link juice to the targeted URL but the difference between the 2 results seem way too big for me.
What do you think? Is this normal?
During future link building is it more beneficial to target the root domain so the page won't lose that "10%" by redirecting the new link from sub-domain to root domain?
Is it possible to get more juice transferred?Thank you very much,

Hey
I'm a bit confused - not the first time! Would very much appreciate if you good folks could shed some light on a couple of questions.
Our site in the search console is inputed as www.domain.co.uk
Is this our subdomain?
When I'm using Open Site Explorer and filter by Target, say "this root domain" is it now showing me inbound links to domain.co.uk instead?
Lastly how does this affect rankings i.e getting links to www.domain.co.uk or domain.co.uk as whoever types in either domain gets to the correct site.

Thank you CKG for your answer, it's much appreciated.
I have already started to move to www. , I changed in WordPress settings, from non-www to www version, also selected the preferred version www. in webmaster tools and contacted the server administrators about the change. My only last problem is the battle with the htaccess to redirect the rootdomain to the www. subdomain but I should get it sorted out pretty soon

Cheers,

Hey
I think you should go through both for analysis purposes however in order to moving forward you should be focusing on one URL which contains www.
here are the link for you to help yourself to understand the difference between these.

I have just come across the same issue for a site I am optimising. For me, when www is used the page authority in OSE is 42 compared to 33 when there is no www.
It would be really good to hear what people's views are on this.

slug Link redirect to subdomain?
Hi !
Link Building | | Leviiii
Im Levi new here and new in the world of SEO, please dont judge if my questions are silly. Back on the days when the site was built we thought it is a good ideea to have subdomains that together with the domain name represent our main keywords.
ex. https://stansted.tonorwich.uk, https://heathrow.tonorwich.uk, https://luton.tonorwich.uk, https://gatwick.tonorwich.uk. There is content on this subdomains, would it make any difference from SEO perspective if we create slugs that redirect to these subdomains? for example creating https://tonorwich.uk/taxi-minibus-vip-tesla-norwich-to-stansted that redirects to https://stansted.tonorwich.uk ? Or better create these slugs with slightly different content?
Any ideeas would be appreciated.
Thanks in advance!0 -
Redirecting dofollow, high-domain-authority links from one site to another: good idea?
I have two sites that offer help for freelance writers. The first gets almost no search traffic and is very low priority for me. The second is my main priority and gets substantial search traffic. The low-priority site has a significant number of dofollow backlinks from high-domain-authority sites. Is it a good idea to 301 redirect these links to similar/related posts on my high-priority site? Would this potentially boost the SEO of my high-priority site? Thanks for any help!

How do we optimise links from a parent company to a subsidiary on different domains
So we are the agent for an industrial company. They don't have a great website (well its pretty but doesn't rank) and have 5 product pages with a variety of products on each. We've taken those products and turned them into 50 pages with good on page optimisation. Now they've just agreed to give us a link on each page and I'm trying to figure out what the best text and link will be. As far as I can see there are three options Visit our agent for X region - sending to the home page If you are from X region you can request a sample of product group from our agent - sending to home page and product category page on our site If you are looking for X, Y, Z or P, Q, R in this region contact our agent there. - sending to home page and individual product pages The aim of this is to boost my page authority as 98% of the top 10 in SERPS have pages with zero authority and rely on the on page optimization and DA. Is this the best approach or are there other better ways of approaching the problem. It's worth noting that there is a total separation of control and ownership of the websites. I'm also starting to work with them to improve their on page optimisation and get links from their parent company to increase link juice

It is ok to link together multiple domains on the same ip?
I have multiple domains (more than 50) in the same niche. All domains are on the same ip. It is ok to link them together, or to create a piramid link between them?

Outgoing links - internal vs. external
I thought that the important factor in the value of a link was how many outing links a page has total. Some tools seems to tell me that the important data point is how many EXTERNAL links a page has. Which number should I be paying attention to when looking at pages I want to get linked from? (Yes, I know there are many other factors that are important)

Iframes vs links
Obviously, websites can link to another web site using iframes, and Google and other search engines do seem to have some capability to index the content. What I want to know is what is the difference in value passed between a regular link and an iframe link. <iframe src="http://www.targetwebsite.com/targetlink"><br /><br />will have the same page ranking effect on the target web site as this link: <br /><br /><a href="http://www.targetwebsite.com/targetlink">link</a><br /><br />Alternative, would it work to include an invisible actual link right before the iframe, like this: <br /><br /><a style="display: none;" href="http://www.targetwebsite.com/targetlink">link</a><br /><iframe src="http://www.targetwebsite.com/targetlink"/></p> <p><span style="color: #5e5e5e;">The reason is that we are building a product recommendation engine, for a branded cosmetology school in order to get our concept salons to link back to use and I was curious if creating a version they can use as an iframe will give us link benefit.</span></p></iframe>

Can link juice be passed in an iframe from domain A to domain B
Need to give our web partners our booking form which must be loaded in an iframe calling back to our domain. Is it possible to pass any link juice from their domain loading our iframe back to us. Was thinking of a "Powered by" text link in the form footer, but I'm guessing the link needs to be outside the iframe. Would love to hear any thoughts or workarounds on this.
