does linking to site subdomain consider as outbound link

I am planning to start a site but plan to put in subdomain each category of my new site.. and there are more less than 100 categories of this new project... my concern is than does linking to each subdomain considered as outbound link of my main site and my site will be penalize by SE?

example my main domain is site.com the create subdomains by category like category.site.com category2.site.com, category3.site.com etc...


Next question is that does SEs consider duplicate content, category2.site.com and site.com/category2/ since both url have the same content...

 

Yes, each link to your subdomains is an outbound link. No, you won't be penalised (why would you?)

Dup content is dup content. But why have you duplicated your content in this way?

 

No I am not duplicating my site content but when you create a subdomain in cpanel this also consider as folder so you can access in either way subdomain.site.com or site.com/subdomain so both content are the same

example http://recipes.edraft.net/ and http://www.edraft.net/recipes/

 

yes !

but in my experience they are valued to some extent and then their weight is ignored.

 

A subdomain is considered a seperate site, at least from what i read on this forum.

 

There is nothing wrong with linking to subdomains from your main site. A subdomain is considered a different site by google and the link will pass PR, but it isn't going to be considered a "vote" for your site like another, unrelated domain linking to the sub-domain - as they are on the same class "C" IP which makes google assume same ownership. Owners "voting" for their own site goes against the intent of google's algorithm for SERP's (but there's not going to be a penalty).

 

Thanks mjewel for the explanation....

 

It "usually" works best to link to your subdomains... but not link back from the subdomains to the main domain.

 

I don't think that is true. It's true that regular one-way links are given more weight, but since these are likely hosted on the same server with the same IP, it isn't going to matter as google discounts those anyway because they share the same ownership.

 

Linking TO your subdomains work... to establish your subdomains.

That's why you DON'T link back from them... it's a recip link then and discounted.

 

Sure it works for google finding the subdomain, but it's automatically discounted because its on the same IP. Google automatically assumes links from the same class C IP are owned by the same person and that isn't a "natural link" which google will use to increase your SERPS.

 

This isn't true... you need something like domaintoaster to do this.

[THIS IS NOT AN AFFILIATE LINK!]
check out www.DomainToaster.com and you can read about "folders" in subdomains, and it's true stuff.

 

I was a very interesting post by a guy who made about 5 billions subdomains, and on every search in google, his pages comes firsts.
By that time Google certain allowed multiple subdomains without any penalties. I guess there were several attemps like that one, so Google had to changed a little bit its algorithms regarding multiple subdomains.

You know, that subdomains are considered different sites and there can placed more then 2 per result page, so it's a very useful thing to make all of your categories a new subdomain?

http://category1.mydomain.com is a subdomain, when http://mydomain.com/category1 isn't a subpage? aren't those two different things??

I want also to know the answer of this question

 

http://category1.mydomain.com is a subdomain, the other isn't.


http://forums.digitalpoint.com is a subdomain not http://www.digitalpoint.com/tools/ad-network/

If http://www.mydomain.com had a PR5, http://www.mydomain.com/category1 would usually get a PR4 (assuming no direct links to the sub-page as 85% of PR will pass). If you create the subdomain http://category1.mydomain.com and didn't link to it from http://www.mydomain.com (or another sub-page), it wouldn't have any PR as google treats it as a different domain.

 

mjewel, thanks for clarifying everything.

Now let's back to the first question.. it will still work to create subdomains for each new category, even for each sub-category and so on.. or Google has invented some penalties?

I'm talking from a period of time no longer then 4-6 weeks.

There is nothing wrong with subdomains. What google allows today, they might not tomorrow. If it makes sense to use subdomains, then use them. If you are only doing something to try and manipulate SERPS, then I would stay away from it. If you want to do 10 sites on completely unrelated topics, then getting 10 different relevant domains is going to be better.

i.e. http://california.realestateagents.com makes sense. mesothelioma.realestateagents.com doesn't. One problem with sub-domains is that the url is longer and you are likely to greatly reduce any type-ins. It also depends on why you are doing it - it's done often with PPC to help CTR due to relevance.

If you aren't going to build backlinks for each sub-domain, then you should be linking to all the subdomains from the home page. Having 200 different subdomains and sub-categories linked from the TLD home page isn't something I would advise.

 

Subdomain with same content may cause penalty.

 

Yes everyone knew that, the question being ask is that does the content of the subdomain and subfolder access considered as duplicate content....

e.g. category1.domain.com and domain.com/category1

 

The urls alone are not going to cause you any problem. Duplicate content is based on the content of the page, not the url name. In your example, if the content on the pages are different, you are fine. If the content is the same, it is duplicate content regardless of if it is on a sub-domain, different page, or an entirely different site. Google tries to determine the first page that had the content, and considers all other pages with the same content as a duplicate. Giving two identical pages different page names does not get around duplicate content.
