Mozbar question

[activitysuper]

Hi,

In the mozbar it has the following for this post:

PA: 55

mR: 3.28

mT: 4.43

DA: 88

What does this data mean and how would you use it to spot a weakness in a competitor?

Now the domain strength is very high 88, so I know you would have trouble attacking that if your own DA was 48.

p.s this is just an example

The definitions for the mozBar metrics can be found in the URLs below:

PageAuthority - http://www.seomoz.org/learn-seo/page-authority
mozRank - http://www.seomoz.org/learn-seo/mozrank
mozTrust - http://www.seomoz.org/learn-seo/moztrust
Domain Authority -  http://www.seomoz.org/learn-seo/domain-authority

For spotting a weakness in a competitor, I wouldn't rely solely on the mozBar.  But for all intents and purposes of your question I would look at two key metrics to compare: the PageAuthority and total number of linking root domains.

PA gives you an idea of how much more/less authority you have compared to your competitor's page.  The number of linking root domains gives you a rough benchmark of how many more unique linking domains you'll need to catch up to them.

Hope that helps!
