Good moz rank and trust, terrible page and domain authority

[adrianmn]

I have this happening both for page and domain.

For domain the rank and trust are 5.2 and 5.51 but domain authority is only 48. My competitors with trust and rank between 5.5 and 6 have their domain authority in the 70-80 range.

The same happens for home page metrics and the metrics are about the same.

What can cause this authority discrepancy?

Not being able to see your domain and that of your competitors makes answering this question with specifics a bit challenging, but SEOmoz defines PA and DA as predicting a page or domain's ranking potential in the search engines based on an algorithmic combination of all link metrics.

That said (or defined) I would surmise that you have good links, just not as many as your competitors, and your competitors probably have more than a few strong links from domains with authority (in both PageRank and  Trust). Check out the image below. It shows a client's site (top) and five competitors. While it doesn't reflect your situation of a higher DA , it really demonstrates the effects of quality and quantity.

We have the most external links, but with fewer root domains than competitor two, and that domain's have a higher DA to PA ratio for the top five links than we do (90/28 vs. 70/60)

Definitely use the SEOmoz Competitive Link Comparison in your campaign vis-à-vis your competitors

Our global link popularity metric, calculated in a similar fashion to Google's PageRank (on a log scale between 1-10).
