Is it normal for my homepage's page authority to be higher than my domain authority?

[mjk26]

Hi everyone,

I've just been checking my MOZ authority scores, and the page authority of my home page, www.concerthotels.com is 53 (mozRank of 6.16) which seems pretty good to me.  However, the domain authority is only showing as 45.  Is this typical?  There is such a big difference between these two scores - what does that suggest?  Is there anything obvious that I can do to bring the domain authority up to the level of authority that the homepage commands?

Similarly, the UK version of my site has a homepage authority of 41, but the domain authority is only 30.  Looking at numerous other websites, quite often the homepage and domain authority scores are very similar, or the domain authority is slightly higher, so it does look as if this is unusual.

Any comments would be greatly appreciated,

Many thanks

Mike

According tot he data moz has on your web site they think your homepage has better chance of ranking as opposed to other pages on the domain. I would not be too worried about it, you can mitigate it by building quality links to some of your other top internal pages
