Use of subdomains, subdirectories or both?
-
Hello, i would like your advice on a dilemma i am facing. I am working a new project that is going to release soon, thats a network of users with personal profiles seperated in categories for example lets say the categories are colors. So let say i am a member and i belong in red color categorie and i got a page where i update my personal information/cv/resume as well as a personal blog thats on that page. So the main site is giving the option to user to search for members by the criteria of color. My first idea is that all users should own a subdomain (and this is how its developed so far) thats easy to use and since the domain name is really small (just 3 letters) i believe subdomain worth since personal site will be easy to remember. My dilemma is should all users own a subdomain, a subdirectory or both and if both witch one should be the canonical?
Since it said that search engines treat subdomains as different stand-alone sites, whats best for the main site? to show multiple search results with profiles in subdomains or subdirectories?
What if i use both? meaning in search results i use search directory url for each profile while same time each profile owns a subdomains as well? and if so which one should be the canonical?
Thanks in advance,

This is one of the reasons I love this forum: it requires thinking because many who ask questions are thinking. (think about it;) While I understand what eyepaq is saying in one sense that search engines "could" treat them as stand alone; it appears search engines do/could because as the subdomain holder you are not seeing links going only to the main domain or other subs, you are the one who controls it, can move its hosting, etc. But, according to Google, they do not in the sense of linking:
If you own a site that’s on a subdomain (such as googlewebmastercentral.blogspot.com) or in a subfolder (www.google.com/support/webmasters/) and don’t own the root domain, you’ll still only see links from URLs starting with that subdomain or subfolder in your internal links, and all others will be categorized as external links. We’ve made a few backend changes so that these numbers should be even more accurate for you.
Note that, if you own a root domain like example.com or www.example.com, your number of external links may appear to go down with this change; this is because, as described above, some of the URLs we were previously classifying as external links will have moved into the internal links report. Your total number of links (internal + external) should not be affected by this change.
So, as for external linking, it is clear that if there ever was a question about domains and subdomains, there is none now. But, that does not mean you should not use subdomains. Eyepaqs point around user abuse is an excellent one, but you should also be monitoring this like a hawk.
At the end of the day, I would think that using subdirectories is going to be easier if you are planning on a large site. But, the ease you mention for the user with the short domain name is intriguing. I agree with Muhammad on sub domains might get a little expensive and, if your choice is to use both (I wouldn't as it seems to me that you are creating more and more work for your dev team) the canonical should be the subdomain.
Again, thanks for the thought provoking question.

Hi,
Since it said that search engines treat subdomains as different stand-alone sites,
** Search engines could treat subdomains as different stand alone sites. Usually they don't. A good example when they do that is the blogspot subdomains - and that is because those are in fact separate stand alone sites.
In your case however, since it's about users, similar with blogspot somehow - google can treat them at som point as separate websites.
whats best for the main site? to show multiple search results with profiles in subdomains or subdirectories?
** My personal opinion is that from a user point of view you should go with the subdomains as you do right now - it make sense, it's easy for them to use those urls, to link to them and so on.
You could lose some link equity for the main domain if some or all subdomain will be at some point treated as separate domains but if you put everything on a scale, it will balance as advantages on the subdomain approach anyway.
What if i use both? meaning in search results i use search directory url for each profile while same time each profile owns a subdomains as well? and if so which one should be the canonical?
** To be honest I do see the point / advantages in doing that.
One other advantage is that if you go with subdomains and google will count them as separate websites, if one of your user is ding something stupid (trying to rank with it and start building gambling and porn links to that sub domain you will be safe with the root domain and the other users won't be affected.
Hope it helps.

Hi HaCos,
Well it depends on how many users are there? thousands of users with thousands of sub domains is an expensive option. Go for user subdirectories instead of sub domains. And as each user got a sub domain too, so make that sub domain canonical of user sub directory. Hope this answers your question.

Is using a subheading to introduce a section before the main heading bad for SEO?
I have noticed a popular trend in web design which involves sections of content being started with what looks to be smaller sub heading something like <h3>, <h4> or <h5> and then followed by a bigger heading <h2>. My question is, what is the best way to deal with this visual structure and will having a structure like this hurt your SEO? <h5>Contact Us</h5> <h2>Get started with your next project in minutes!<h2> <p>Some text here ...</p> Here are some examples where the header structure is similar to above (smaller before bigger): https://www.snappr.com/ https://form.taxi/ https://fluz.app/ If that structure is bad for SEO, then it seems like a simple solution is to make it purely visual, mimicking a sub header with styling on a span or paragraph like these sites do: https://www.andrejilderda.nl/ https://nightwatch.io/ https://www.swingvy.com/ https://www.figma.com/ My only concern with that approach is because your section sub heading is no longer an actual header you will miss out on ranking important and relevant keyword information for that section. Is this correct something to be worried about? There is one last solution I stumbled upon that involves using headings for both but in reverse hierarchy so a <h3> is first but styled to be smaller, followed by a visually bigger <h4> which provides the addition context. https://avocode.com/ Anyone have thoughts, expertise or resources on the matter?

Should I use meta noindex and robots.txt disallow?
Hi, we have an alternate "list view" version of every one of our search results pages The list view has its own URL, indicated by a URL parameter I'm concerned about wasting our crawl budget on all these list view pages, which effectively doubles the amount of pages that need crawling When they were first launched, I had the noindex meta tag be placed on all list view pages, but I'm concerned that they are still being crawled Should I therefore go ahead and also apply a robots.txt disallow on that parameter to ensure that no crawling occurs? Or, will Googlebot/Bingbot also stop crawling that page over time? I assume that noindex still means "crawl"... Thanks 🙂

Using disavow tool for 404s
Hey Community, Got a question about the disavow tool for you. My site is getting thousands of 404 errors from old blog/coupon/you name it sites linking to our old URL structure (which used underscores and ended in .jsp). It seems like the webmasters of these sites aren't answering back or haven't updated their sites in ages so it's returning 404 errors. If I disavow these domains and/or links will it clear out these 404 errors in Google? I read the GWT help page on it, but it didn't seem to answer this question. Feel free to ask any questions that may help you understand the issue more. Thanks for your help,

Microsites: Subdomain vs own domains
I am working on a travel site about a specific region, which includes information about lots of different topics, such as weddings, surfing etc. I was wondering whether its a good idea to register domains for each topic since it would enable me to build backlinks. I would basically keep the design more or less the same and implement a nofollow navigation bar to each microsite. e.g.
Intermediate & Advanced SEO | | kinimod
weddingsbarcelona.com
surfingbarcelona.com or should I rather go with one domain and subfolders: barcelona.com/weddings
barcelona.com/surfing I guess the second option is how I would usually do it but I just wanted to see what are the pros/cons of both options. Many thanks!0 -
Using the same content on different TLD's
HI Everyone, We have clients for whom we are going to work with in different countries but sometimes with the same language. For example we might have a client in a competitive niche working in Germany, Austria and Switzerland (Swiss German) ie we're going to potentially rewrite our website three times in German, We're thinking of using Google's href lang tags and use pretty much the same content - is this a safe option, has anyone actually tries this successfully or otherwise? All answers appreciated. Cheers, Mel.

Disavowin a sitewide link that has Thousands of subdomains. What do we tell Google?
Hello, I have a hosting company that partnered up with a blogger template developer that allowed users to download blog templates and have my footer links placed sitewide on their website. Sitewides i know are frowned upon and that's why i went through the rigorous Link Audit months ago and emailed every webmaster who made "WEBSITENAME.Blogspot.com" 3 times each to remove the links. I'm at a point where i have 1000 sub users left that use the domain name of "blogspot.com". I used to have 3,000! Question: When i disavow these links in Webmaster tools for Google and Bing, should i upload all 1000 subdomains of "blogspot.com" individually and show Google proof that i emailed all of them individually, or is it wise to just include just 1 domain name (www.blogspot.com) so Google sees just ONE big mistake instead of 1000. This has been on my mind for a year now and I'm open to hearing your intelligent responses.

Sitemap on a Subdomain
Hi, For various reasons I placed my sitemaps on a subdomain where I keep images and other large files (static.example.com). I then submitted this to Google as a separate site in Webmaster tools. Is this a problem? All of the URLs are for the actual site (www.example.com), the only issue on my end is not being able to look at it all at the same time. But I'm wondering if this would cause any problems on Google's end.

Disavow Subdomain?
Hi all, I've been checking and it seems like there are only 2 options when disavowing links with Google's tool. Disavow the link: http://spam.example.com/stuff/content.htm Disavow the domain: domain: example.com What can I do if I want do disavow a subdomain? i.e. spam.site.com I'm also assuming that if I were to disavow the domain it would include all subdomains? Thanks.
