Why some domains and sub-domains have same DA, but some others don't?
-
Hi
I noticed for some blog providers in my country, which provide a sub-domian address for their blogs. the sub-domain authority is exactly as the main domain. Whereas, for some other blog providers every subdomain has its different and lower authority.
for example "ffff.blog.ir" and "blog.ir" both have domain authority of 60. It noteworthy to mention that the "ffff.blog.ir" does not even exist!
This is while mihanblog.com and hfilm.mihanblog.com has diffrent page authority.

Hey!
DA scores are specific to the root domain, we are not taking into account a subdomain. So even if you search a subdomain that doesn't exist (ffff.blog.ir), DA score is still only relevant to the root domain (blog.ir) which does exist.
Page Authority on the other hand is specific to the exact page you are searching, so it makes sense that mihanblog.com and hfilm.mihanblog.com would have different page authority scores are they are separate pages.
Hope that helps, let me know if you have further questions.

Am pretty sure that Moz just unifies DA stats in some circumstances when they have no 'actual' data for the subdomain in question. Sites which are very important, which have a number of sub-domains (but not hundreds or thousands) often render different results for DA metrics. For some blog platforms (blogger is a good example, also "blogname.wordpress.com" WordPress hosted blogs) - they have thousands or hundreds of thousands of sub-domains and Moz can't index all of them
In these situations, if Moz comes across a subdomain which is well-linked across the web it will separate it out and ascribe unique values. For the rest (of which Moz holds no data), it probably just unifies the DA metric with the root domain
It's a symptom of an incomplete index of the web. That being said, no one has a complete index of the web - you have to work with what you got

My keywords aren't performing for my Umbraco site
A client of mine has just redesigned their site which was pretty small (homepage, about us page and contact us page) and now it includes homepage, about us page, 3 services pages, 5 blog posts and a contact us page. their domain authority is 5, so that gives you an idea of their size. We updated their key pages with keyword optimised content and added the keyword to their meta title and meta description. they're in the process of adding the alt tags and also they need to enable meta tags for the blog posts. Everything is quite in the process at the moment and their organic traffic is low. But I believe that some of the keywords should start moving places for the pages that have been optimised and they haven't. Is there any reason for this? I believe the services pages which have meta tags should have started ranking at least in very low position for the selected keywords. Is there something I'm missing? Thank you!

Crawl and Indexation Error - Googlebot can't/doesn't access specific folders on microsites
Hi, My first time posting here, I am just looking for some feedback on a indexation issue we have with a client and any feedback on possible next steps or items I may have overlooked. To give some background, our client operates a website for the core band and a also a number of microsites based on specific business units, so you have corewebsite.com along with bu1.corewebsite.com, bu2.corewebsite.com. The content structure isn't ideal, as each microsite follows a structure of bu1.corewebsite.com/bu1/home.aspx, bu2.corewebsite.com/bu2/home.aspx and so on. In addition to this each microsite has duplicate folders from the other microsites so bu1.corewebsite.com has indexable folders bu1.corewebsite.com/bu1/home.aspx but also bu1.corewebsite.com/bu2/home.aspx the same with bu2.corewebsite.com has bu2.corewebsite.com/bu2/home.aspx but also bu2.corewebsite.com/bu1/home.aspx. Therre are 5 different business units so you have this duplicate content scenario for all microsites. This situation is being addressed in the medium term development roadmap and will be rectified in the next iteration of the site but that is still a ways out. The issue

About 6 weeks ago we noticed a drop off in search rankings for two of our microsites (bu1.corewebsite.com and bu2.corewebsite.com) over a period of 2-3 weeks pretty much all our terms dropped out of the rankings and search visibility dropped to essentially 0. I can see that pages from the websites are still indexed but oddly it is the duplicate content pages so (bu1.corewebsite.com/bu3/home.aspx or (bu1.corewebsite.com/bu4/home.aspx is still indexed, similiarly on the bu2.corewebsite microsite bu2.corewebsite.com/bu3/home.aspx and bu4.corewebsite.com/bu3/home.aspx are indexed but no pages from the BU1 or BU2 content directories seem to be indexed under their own microsites. Logging into webmaster tools I can see there is a "Google couldn't crawl your site because we were unable to access your site's robots.txt file." This was a bit odd as there was no robots.txt in the root directory but I got some weird results when I checked the BU1/BU2 microsites in technicalseo.com robots text tool. Also due to the fact that there is a redirect from bu1.corewebsite.com/ to bu1.corewebsite.com/bu4.aspx I thought maybe there could be something there so consequently we removed the redirect and added a basic robots to the root directory for both microsites. After this we saw a small pickup in site visibility, a few terms pop into our Moz campaign rankings but drop out again pretty quickly. Also the error message in GSC persisted. Steps taken so far after that In Google Search Console, I confirmed there are no manual actions against the microsites. Confirmed there is no instances of noindex on any of the pages for BU1/BU2 A number of the main links from the root domain to microsite BU1/BU2 have a rel="noopener noreferrer" attribute but we looked into this and found it has no impact on indexation Looking into this issue we saw some people had similar issues when using Cloudflare but our client doesn't use this service Using a response redirect header tool checker, we noticed a timeout when trying to mimic googlebot accessing the site Following on from point 5 we got a hold of a week of server logs from the client and I can see Googlebot successfully pinging the site and not getting 500 response codes from the server...but couldn't see any instance of it trying to index microsite BU1/BU2 content So it seems to me that the issue could be something server side but I'm at a bit of a loss of next steps to take. Any advice at all is much appreciated!0 -
Why isn't google indexing our site?
Hi, We have majorly redesigned our site. Is is not a big site it is a SaaS site so has the typical structure, Landing, Features, Pricing, Sign Up, Contact Us etc... The main part of the site is after login so out of google's reach. Since the new release a month ago, google has indexed some pages, mainly the blog, which is brand new, it has reindexed a few of the original pages I am guessing this as if I click cached on a site: search it shows the new site. All new pages (of which there are 2) are totally missed. One is HTTP and one HTTPS, does HTTPS make a difference. I have submitted the site via webmaster tools and it says "URL and linked pages submitted to index" but a site: search doesn't bring all the pages? What is going on here please? What are we missing? We just want google to recognise the old site has gone and ALL the new site is here ready and waiting for it. Thanks Andrew

Menu & Sub menu structure - section specific sub menu?
Hi, At present I have a set of regions across the nav bar with drop downs for towns within these regions. This totals about 60 links. This set up is pretty much site wide and the site ranks well for many of these towns. However, this is quite a lot of links per page (without the page specific/content links) and I am wondering about having just a horizontal sub menu of towns appear below the nav bar only specific to the selected region. Do you think cutting down the number of menu links will be beneficial to the content page's ranking. Sorry if that isn't very clear, can't think of a better way of putting it. TIA,

Hide H1 tags on pages. Don't chuckle-Need assistance.
I redesigned my companies website and I am first and foremost an SEO person so I know the importance of a well laid out website. Furthermore, I know realistically you should NEVER hide text whether it's with WH or BH intentions but here is my problem. For every page I have all the details taken care of except proper placement of H1 tags. My website is responsive designed VERY competitive industry I have to make sure it is properly developed both design wise and seo wise It's an INC 5000 company so NO BH intentions On phones and tablet devices I have the header images hidden and in the place of header images I have the information as in location, service,etc of whatever that page may be. This makes it look good on desktops and serves up information quickly to people using phones and tablets. My question is: Would it be bad to turn that text seen on tablets and phones into an h1 tag as it's hidden on desktops with CSS but available on mobile devices. My problem is making the h1 tag's work with the desktop versions visually as placement doesn't make since. Any opinions are appreciated. Thanks Ballanrk

Website domain hosting and set-up for foreign domains?
Hi, I am just wondering what the best practice is for marketing a business in two separate countries? I have a new client that wants me to create their website targeted at the UK market which for me is normal but they also want to target Australia (Probably couldn't get any further away) My initial thoughts are that the business would need two separate websites. The first one in the uk and the second website hosted on servers in Australia with different content. Is this correct? or does anyone have any advice which may simplify getting this thing off the ground. Thanks in advance.
