The question is…why is PR the only metric used by so many webmasters to value a page on the web? There are so many other valuable metrics; traffic, backlink count and actual rankings to name a few. The obvious answer is that we are lazy and PR is the quick and easy way to determine some semblance of value, no matter how flawed (or antiquated) PR really is.
So, last week Open Site Explorer was launched by SEOMoz, and along with this new SEO tool are some interesting metrics called Page Authority and Domain Authority. While these aren’t perfect metrics, they seem to provide more depth to them than simple PR, especially since OSE also shows you the links and domains linking into a website.
Here’s how they explain it:
Domain and Page Authority scores are both calculated using SEOmoz’s Ranking Models work. In essence, we take a lot of rankings data from the search engines (by running queries) and then try to build a predictive scoring system using our own on-page analyses and Linkscape link data to construct an algorithm that will effectively reproduce the search engines’ results. Our current accuracy hovers in the 70% range, but over time, we expect to improve.
Now that this metric is out there, will you be looking at Page Authority when exchanging/buying/selling a link?
as for the Seomoz tool, it’s just a jumped up version of siteexplorer from what I could see, altho it does offer some added functionality/bells and whistles [siteexplorer closing soon, queue the seomoz guys entering the fray to make some $$$…]. One can probably write a few scripts to do the same job for free using the SE APIs.
I like the Page Authority idea a lot. SEO moz has some gret SEO minds over there.
Thanks for sharing!
From some research it also seems that it doesn’t have too much impact on rankings. I have seen similar sites, one that had high page & domain authority on OSE and the other which outranked it for every term. Unless the first guy had horrible on page it would seem OSE wasn’t a really good measure of what it took to rank, which quite frankly is all I am concerned with.
85/100 pr4
47/100 pr5
thats how some of mine ranked up.Obviously for link sales the 47/100 pr5 will get more than the pr4 85/100.Google has brainwashed us for years ,they send us 80%+ traffic so hard to change our ways now
