It is possible to view the older Domain Authority for a domain with open site explorer?

Thanks.

I think that is not possible but you can look at older pagerank values here: http://livepr.ezer.com/

You can view older PR in SEOmoz tools historic PR checker. Historic domain authority but I do not think you can.

Unfortunately at this time it is not possible to view historic Domain Authority metrics. There are a couple of reasons for this, including the prohibitive cost of maintaining older indexes (my understanding is they are extremely large and to maintain/store/serve.)This may change in the future, but right now there is no access to historic indexes.

The other reason is that metrics like Domain Authority are comparative metrics that change from index to index. This means that it's best to use these numbers to compare yourself to the competition, but not to your own previous metrics as the base calculations can change. DA measures relative strength - so it's completely possible to improve 10% by raw numbers, but if your competition improved 10% as well, your relative DA really didn't change. For this reason we caution against folks measuring DA over time, and instead using it as indicator of ranking potential in real time against other competitors.

That said, SEOmoz does offer a Historic PageRank checker that does work for many domains. It's kinda fun.
