Over the years people have come to rely heavily on Google’s Page Rank as an indicator for a site’s authoritativeness. It’s still a very prominent metric but people (esp. SEM Experts) are now beginning to understand that there’s a whole lot more to it.
For example a site with low Page Rank can still have thousands of visitors and do well from a search engine perspective.
I think people still like to have that 1, all encompassing value and I am trying to wrap my head around how that number would be determined for Blogs.
BlogInfluence.net uses the formula: [(blog+posts+web links) + (bloglines subs * 2)] * 1+(PageRank/10) (using Yahoo Back Links, Technorati Back Links, Blog Lines Subscribers and Google Page Rank).
I believe there should be a few more metrics added to this formula which would help strengthen its value:
– Yahoo and Google News links (for authority)
– FeedBurner Subscribers (for readership)
– Technorati Rank (for authority)
– Back-links from Major Search Engines with some type of weighting applied (i.e.: Google = 10, Yahoo = 6, MSN = 4)
– Unique Visitors
– Alexa Reach/Rank
– Digg, Delicious Votes
There are probably many more metrics we could add and I would love to hear suggestions from others.
A formula combining all of these metrics would really help measure how well a blog is doing, especially after implmenting a blog promotion strategy.
With the various APIs available to us, I don’t see why this measurment couldn’t be developed into some type of software tool or webpage.
