    I have a website for multiple niches and I was wondering, if is better to use subdomains or multiple inner pages? Because I'll be building backlinks from the same lists.

    So, something like:
    niche1.domain.com
    niche2.domain.com
    niche3.domain.com

    OR

    domain.com/niche1
    domain.com/niche2
    domain.com/niche3

    Which is better one?

    Generally I've found clean sub pages are better than sub domains. But they do need to be clean. By clean I mean;

    mysite/subpage

    and not

    mysite/someotherjunk/subpage

    The further down the scale a page is, the harder it is to rank. But on average a subpage is slightly better than a subdomain.

    A subdomain is a completely different website so your first example would be treated as if you had bought different domains for each product.

    The second example would be treated as the same website so it's completely up to you if you want links coming from the same lists and if you want to spend the time and money on ranking a different site for each niche.

    Have to agree to disagree here. You can create a new website on a sub domain or a sub folder (sub URL). The SE's know what subdomain.maindomain is, and for serps purposes they do not treat it as a different site, they treat it as a sub domain. In practice folders (sub pages) pages, as long as you don't have convoluted rel structures, rank a little better than subdomains.
    I always hoped SD's would rank better, it's something I thought would be good myself in the past.

    The fact that subdomains don't work better than sub folders has always seemed a little counter intuitive to me, but that is the way it is - in practice they just don't.

    Authority from the main site travels to and from sub pages better than it does to sub domains. Why? Don't know, but it seems to be the case.
    http://www.seoandy.net/optimisation/subdomain-vs-folder-vs-external-url/

    One of many articles on the web that discuss this in more detail. Most come to the same conclusion - though to be fair there isn't a lot in it.
    None of the articles are mine - just search "SEO subdomain or folder" and see these articles for yourself.

    Roughly a subdomain is treated as a fresh domain, but not entirely exactly. Asuming you dont link form main domain to subdomain, the sd is almost as a fresh domain. A subfolder/page on main domain would instead get DA of the domain. A subdomain will not get the DA of the parent domain. If you link from main.com to sub.main.com then you pass link juice and other stuff.

    The only advantage i see for subdomains is they allow you to get more pages indexed. So if you try to index 100k pages on main.com will take longer or more links than if you put 1000 pages/subdomain on 100 subdomains.

    There are also WH reasons to use a subdomain rather than subfolder. For example a company which has multyple types of products (e.g. office.microsoft.com). Or to allow you to use a separate geolocated host (e.g. de.wikipedia.com would be hosted in Germany).

    There are a bunch of other details.

    The way google and others deal with subdomains has changed a lot over time. Right now each subdomain is a separate website and you need to invest almost as much in it as you'd invest in a brand new domain. Once the site reaches a certain size, you can have the luxury of adding more subdomains without having to invest as much, but for new sites it's like opening many SEO fronts, so I'd stick with subpages.

    Will sub folder be treated the same by Google in these two cases:
    1) static html pages uploaded to the sub folder created manually (xxxx.com/ironman)
    2) dynamic php pages with htaccess tweaks something like xxxx.com/page.php?movie=ironman + htaccess tweaks = xxxx.com/ironman
    it has the same url but those the Google treat it differently?

    Hi. Sorry but I disagree with you . A subdomain will get the DA of the parent domain. As an example if you create a site like mynewsite.wordpress.com it will have a DA of 100 (same as the parent wordpress.com ). So it may be a good option to invest on your own domain instead of trying to rank a domain for totally different niches , say IM , weight loss, e-cigars , etc It may makes more sense to create a im.mydomain , weighloss.mydomain , etc ... Instead of starting from a fresh new domain like im.com with a PA, DA = 1 you would start with a DA equals to the same as your mydomain. what do you think ?

    Hi Guys,

    Sorry i have to bump this up a little .

    I had a client who wanted to rank subdomain.
    I never had this kind of client before, i successfully ranked for subpage and main url.

    The issue, the main domain is just hostgator default page, there is no content or wordpress.
    But my client install wordpress on a subdomain.

    dogtraining.myclient.com <-- Installed Wordpress.
    myclient.com <-- default hostgator landing page, no content, no website.

    Should i rank the same way as i should, or will it take up double the effort?

    Best Regards,
    SE

    Lets say if i have to talk about one thing (linkbuilding ) more in detail, i will create a category for the main website like abc.com/linkbuilding or abc.com/category/linkbuilding.

    Example :- If we assume matt cutts himself best, then look check his blog mattcutts.com/blog, he has a lot of things(like chrome,web,internet,seo etc ) to discuss in his blog , so he create mattcutt.com/blog/type/chrome

    Now coming to subdomains,
    Let us consider the abc.com, now instead linkbuilding if i have a different service or topic, lets say here i want to talk about "games", so i will create " games.abc.com " ( where abc ofcourse more likely related to search engine optimization ) . To be more precise, i have a multibrand company abc.com, which provides marketing and financial services, then i will create financial.abc.com and marketing.abc.com where financial and marketing are sub brand services.

    Example :- Wikipedia.com , they have sub domains like en.wikipedia.com , de.wikipedia.com, es.wikipedia.com etc , and the same wikipedia also talks about lot more things .

    Another example is Google.com itself, where google.com is search engine, where adwords.google.com , drive.google.com, translate.google.com , play.google.com are different products of google.

    Coming to your site, now i hope you must have understood what to do with your site. :) , if you are creating health based niche, then you should have health.com/diabetes , health.com/headache and if you are providing something different like consultation services, then may be you can have consultation.health.com

    Hope this helps,
    Cheers,:drinking2

    [ The above are just my views and understanding of mine in last few years of my seo career, i believe in learning, so if anyone has anything new or anything different i will be glad to know ]

    For ranking purposes, I would never setup a sub-domain. As Scritty and MadOctopus already mentioned, sub-domains are treated as brand new domains in the eyes of Google.

    If you setup a page (not a sub-domain) on your main domain, the link "juice" will flow down to your pages.

    Hello all. What if those "niches" are almost the same type of products & you want them to rank individually for the same keywords? You go for Sub Dom, Sub Dir or Individual Domain...
