Do the sub domain backlinks count for main domain and increase authority?

[vtmoz]

Hi all,

I just wonder if the back links for different sub domains will be counted and considered to rank the main domain better or they are just limit to sub domain pages? There are many websites which has got multiple sub domains which receive backlinks? So the backlinks to main domain and sub domain weigh same at Google?

Thanks

I guess it probably depends on the website, I think they are counted as 'backlinks' but probably carry less authority.  I guess one benefit is it helps the visibility of your pages to search engines.

Hi Vtmoz

In my experience subdomains are a bad way to go and it is invariably better to reincorporate the content on to your main website in a logical directory structure. There is evidence of some link juice being passed back to the main site if all the sub-domains are linked back to the site in a proper structure.

However, if you are merely trying to increase positions in Google by ranking for subdomains which compete for similar terms to your main site then you are doomed to fail.

You basically end up with a link network which can easily be spotted and penalised.

Hi Nigel,

Thanks for such detailed response. I am afraid that we may hurt ourselves after reading your answer. But we can see many websites which have got number of links from their sub domains, infact from every page of their sub domains and I don't see them penalised.

And what is wrong when we try to divert users from old content to new content? We can see this been employed by many websites when they have something to feed to their customers.

If you are sure about the risk, I would like to get your personal suggestion by looking at our website if you can.

Thank you

Hi vtmoz

There is not a problem if all the content is different and unique to the sub-domain.The problem only comes when you try and rank for content that you are already ranking for on the main website.

The best way is to pull all content on to the main website as it is far better for SEO.

I can understand your comment about other sites doing it but honestly, in my opinion, that is not a reason to follow them. You will get better ranking, more quickly if you combine the whole site together rather than try and promote subdomains. Which frankly just make for a lot more work.

Regards - happy to look at the site

Nigel's suggestions are right on.

We redirected subdomains into folders on the main site and the results were KICKASS.     KICKASS.  We started producing a lot more traffic and making a lot more money.
