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,
Adam -
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.

Creating a subdomain or subdirectory for each major city for our main website...
If our website is abc.com I am wanting to create a subdomain or subdirectory for each major city for SEO targeting purposes. But I want each domain to go to our see the same content from the main website abc.com. What's the best way to accomplish this? Duplicating our main page over and over sounds terrible , especially when trying to make changes down the road. Should we create an alias for each location? example.. abc.com/new-york, abc.com-chicago, etc...? If we go that route how does google acknowledge that? Would that mess up our SEO or help? Thanks!

My site is linked from over 900 "The Globe"-domains - disavow or not?
Hi! As some of you may be familiar with, there is a giant spam-network with the same design and same page title on all domains: "The Globe - The world's most visited web pages". For example: theglobe.at

www.internet-search.us I've now discovered that over 900 of these spam-domains link to my site. My plan was of course to disavow them all, but Google is explicit on telling me to be careful. «Only disavow if you are certain that the links are damaging to your rankings». And to be honest, I'm not sure. Also: it seems drastic to disavow almost a thousand pages. I'm afraid to mess something up. What would you do?3 -
I just uncovered a massive 500+ domain PBN linking to competitors
As the title, some competitors I've been watching are using a PBN they (or their agency) have built. I'm looking to get some discussion on how you approach situations like this - do you just report all of the domains to Google and pray they do something? There are 4 sites I'm looking at, all competing in the same niche with very similar websites (different branding and content, but essentially the same pages). I thought all were related, but after Excel-ing all the domains to see which overlap I've found that there's several sets; PBN 1 covers 117 domains that link to competitors A, B & C. Signaling to me that these are owned by the same person. PBN 2 links together B & C with 30 domains, PBN 3 is just C with 40 domains. PBN 4 is just B with 105 domains. PBN 5 is just A with 10 domains. PBN 6 is D by itself with more than 340 domains. Signaling to me that this one probably isn't owned by the same person. It looks like new domains are added to these PBNs every week and this has been going on for quite some time. Now, I'm fully against use of PBNs that don't use authentic websites that provide value, and I can't find any of these sites that aren't just a basic WP template with a single-word text logo followed by spun content. This is a goldmine, because according to Ahrefs these sites are pulling in well over 500,000 monthly visitors between them, and these links make up the majority of each site's link profile. If these networks were to crumble, that would open up a big opportunity for more authentic sites to rank well. How would you recommend to tackle this? Do I find example URLs and write reports for each of the 500+ domains or are there better ways of working through this?

Moving blogs to different domain
Hey guys, We currently have some blogs on one of our pages (fraserisland.com.au) and we are launching a complete rebranding of our sites. We want to move the blogs from fraserisland.com.au to the new parent page of travelfreedom.com.au (but still link it to fraserisland.com.au), however I don't know what affect this will have on the ranking of the blogs. The biggest thing I'm worried about is that the domain will be completely different, and not a sub domain, but I'm not sure what impact this will have on the effectiveness of SEO on the blog. Thanks guys

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

Text Link vs image link?
Which passes most link juice a text link or an image with the correct 'alt' attribute? Do the pass the same amount or is one more valuable than the other?

Building Links to Exact Match Domains
What are the pros and cons having exact match domain and how can you create a brand name and build backlinks? Say we have a domain personalizedbirthdaygifts.com We are quite stuck with what anchor text we need to use and how do we vary it? I've heard that we have to stay away from using commercial keywords as anchor text heavily. We have to also use our brand name. And here we get stuck as we don't have a brand name. In this case Our brand name should be personalized birthday gifts but this is also commercial keyword. I have seen before similar websites droped from ranking because they have commercial keywords in their domain and most of their backlink anchor texts are commercial. If I had a website called twentyfive.com selling birthday gifts it would be a lot easier. But when you have a website personalizedbirthdaygifts.com and trying to rank for personalized birthday gifts and birthday gifts it's tough. OR isn't it? I hope I explained it well and didn't confuse anybody... Thanks
