Incorrect domain authority result on SEO tool bar and OSE

[jayderby]

The SEO tool bar is returning what I believe to be an incorrect domain authority of 71 and showing 24,356,141 lins from 153,051 domains.

The OSE is also returning 71 as domain authority.

Anyone know what could be doing this?

Thanks.

Could you give us the URL where this is happening?

Why do you think that's wrong?

Is your PR 8+? I know you have about twice as many linking domains than Wikipedia (according to OSE) but that's not all that contributes to authority

www.dalycom.uk.com

Yes Barry I'm sure it's wrong for the reasons you state.

I think it looks pretty OK.

I guess UK.com is a pretty popular website and that's the data you're getting.

Hmm, I wonder how the OSE calculates these sort of subdomains then in terms of DA.

Although, I can't get anywhere near the same number of links to show up in OSE. I get 24M links from 39 domains (that's 39 for uk.com, 20 for the site you linked to, although maybe that's for the awards pages only and the www is different again with 459 domains.).

What page is giving you the 153,000 linking domains?

[Nemek]

UK.com provides subdomains, so there is a lot going on there - site:uk.com

It's a bit weird the way OSE counts linking root domains to the domain:

1. A query for UK.com in OSE will return the linking RD only to pages on UK.com
2. A query for www.UK.com will go deeper
3. And finally a query for www.subdomain.UK.com returns the actual amount of linking RD to all the pages within that level of subdomains on UK.com.

At least that's how I think it works

Thanks for looking in to this guys.

I just thout uk.com was another tld - albeit an unpopular one - and I had no idea this sort of sub domain existed.

Wil lthis continue to affect all of the tools in SEOMoz?

[StalkerB]

Yeah, it probably will continue to give you skewed results in any of these kinds of tools, not really a way around it that I can think of.

I guess you'll need to put more credence into page authority metrics rather than full domain authority when working out a strategy.
