Why PR9 High DA is important...?
With Matt Cutts recently announcing that Google will startpunishing quick-fire guest posts in the upcoming algorithm updates, it has
become tougher for content developers to rank better with sub-par content.
There are no ways to game the system now and it is now level ground for all the
online publishers. DA is another metric used to understand the performance of
your website and it is considered important, as just like G, it is hard to
influence that metric and it takes a lot of factors under consideration before
calculating your DA score.
With even the dropping of updates to Page Rank by G, Domain Authority would soon become one of the key metric to gauge the quality of your website, often needed by advertisers.
