SEOMOZ Stats dont work out

[activitysuper]

Hi,

When I check my mozstats for the homepage it says the PA is 50 but the DA is 30, how can that be?

I would expect them to either be the same or at least the DA to be higher then the PA.

Cheers

Hi,

It is quite possible for Page Authority to be higher than Domain Authority as the two are independent of each other. PA is essentially a measure of how likely an individual page is to rank, while DA applies across entire domains & sub domains.

To understand how PA & DA are calculated and what they actually mean, take a look at these resources Page Authority and Domain Authority.

SEOmoz recently introduced an update to the calculation of PA & DA which has brought a higher level of accuracy. You can read this post about the improvement - Introducing SEOmoz Updated Page Authority & Domain Authority. This one goes into some depth as to the reasons & methods used in calculating both.

Hope that helps,
