Do Addon Domains affect SEO

[stocks]

Do using addon domains make any difference in SEO.

If I got a hosting account that allows addon domains and I use this account to host 20 websites using addon domains is there any effect in seo or would it be better to have all 20 websites on a hosting account and not use addon domains.

Thanks

It doesn't matter, every domain will be treated as a individual domain/website.

You do mean addon domains and not subdomains right?

Your addon domain could be accessed like www.addondomain.com correct?

If so you're all good to go.

i agree......but what do u mean subdomains....i have some show up inmy hosting acct as subdomains....and addon domains....how is this??

 

[Damion]

A subdomain would be for instance: cars.domain.com

An addon domain is a folder you can add to your hosting account and place documents in so that you can have multiple websites in one main account to be accessed under each own individual domain.

Actually addon domains do affect SEO. Each domain would show as having duplicate content of the original domain unless they use a 301 redirect to the main domain name.

If you do get flagged as having duplicate content you have no way of knowing which domains will be penalized for the duplicates. It is quite possible different domains will get penalised for different pages weakening your whole SEO strength.

ok....quick question...if u open a host acct.....shared....and your main url is domain.com....now when u add new domains to that acct....dont they all go under the main acct of domain.com?

i have added additional names as addon domains...but they also appear in my cpanel as subdomains to the main name.....why?....

Is there a way to figure out if they use a 301 redirect? And by they do you mean the host or the way the person has his addon domains set up.

I'm not quite sure how that would be Peter, do you mean a addon domain will be regarded as part of the main domain?

www.maindomain.com
www.addondomain.com

Because the files in the addon domain folder only exist there and not somewhere else. It can only be accessed on one URL right?
Your thoughts are very much appreciated on this.

Those two example URL's is to be regarded as two different separate websites right?

ok....quick question...if u open a host acct.....shared....and your main url is domain.com....now when u add new domains to that acct....dont they all go under the main acct of domain.com?

Yep, that is in my experience the case.

i have added additional names as addon domains...but they also appear in my cpanel as subdomains to the main name.....why?....

Hmm, can't really give you a good answer on this moment, will have to verify this with some of my own hosting accounts.

Ok

There are 2 ways of adding a domain to a cpanel account. 1 is parking and 1 is addon.

Add on domains are usually in a subfolder for the main domain. so a.com might be in a a.com folder.

You can access that folder by either calling a.com directly or by calling maindomain.com/a.com/ this is duplicate content as google will both see it as part of the main domain and as part of the add on domain. The risj is if for some reason someone links to maindomain.com/a.com/. Google will then index from that link and see duplicate content.

With a parked page the domain sits on top of the domain and acts as an alias as such. This 1 is a direct duplicate and as such poses a higher risk.

Got ya Peter :tu:

I remember i noticed a similar situation once like you described with a hosting provider and they took care of it.

The only thing i do in terms of redirects is to point the non-www version of my pages to the www version.

Good thing this thread came up because someone that would want do harm to your sites could easily do so when they know you have the domains you use on one account.

Ok so I just tried adding an addon domain and heres what it says.

Bind reloading on gator287 using rndc zone: [ukcasinosite.com] The subdomain, funkymonkey.ukcasinosite.com has been added.

Using nameservers with the following IPs: xxxxxxxxxxxxxxxxxxxxxx
Created DNS entry for funkymonkey.com
Adding ownership on funkymonkey.com to the user dstocks3 funkymonkey.com was successfully parked on top of funkymonkey.ukcasinosite.com

funkymonkey.com has been setup. It can be accessed via the subdomain funkymonkey.ukcasinosite.com. FTP access has been granted with the user name [email protected] and the password xxxxxxx.

So it says "Adding ownership on funkymonkey.com to the user dstocks3 funkymonkey.com was successfully parked on top of funkymonkey.ukcasinosite.com"

So this would be seen as duplicate content?

 

[Peter]

Yes it would if they got indexed. You need something like the following in a htaccess in the funkymonkey directory:-

RewriteEngine on

RewriteCond %{HTTP_HOST} ^(www.)?funkymonkey.com [NC]
RewriteRule ^(.*)$ http://www.funkymonkey.com/$1 [L,R=301]
RewriteCond %{HTTP_HOST} ^funkymonkey.ukcasinosite.com [NC]
RewriteRule ^(.*)$ http://www.funkymonkey.com/ [L,R=301]
RewriteCond %{HTTP_HOST} ^(www.)?ukcasinosite.com [NC]
RewriteRule ^(.*)$ [url]http://www.funkymonkey.com/[/url] [L,R=301]

This is completely untested but doing a quick couple of tests should check out ok.

 

[Damion]

funkymonkey.ukcasinosite.com should redirect to funkymonkey.com

Here is an article with instructions how to take care of the duplicate content issues for your addon domains.

Save the code to Notepad and save it as a .htaccessfile.

I see Peter also posted something similar for you, implement it and see which techniques will solve your duplicate content issues, there should be only one way to access your site's main domain and subsequent folders/pages.
