Been playing with the Page Strength tool just released by SEOmoz and it does seem to pick up some nice bits of information quickly.   The Page Strength tool tells you

1. The Relative Importance/Visibility of a Webpage
2. The Potential Strength/Ability of a Page to Rank in the Search Engines
3. Data on Popularity, Links & Mentions of the Page Across the Web

I’m not clear this tool gives me anything specific to do but it’s fun to play with - it’s a "metrics" tool for SEO to show you how a specific page measures up (1-10 just like pagerank) but the way that number is derived is different than Google’s calcuation of pagerank.

It looks like there are 13 factors and I’m not sure if all are weighted equally.  Here’s the Page Strength readout for one of my clients, below:

Factors

• Links pointing to full URL:

  20%

  Source: Yahoo

  469

• Links pointing to domain:
  19%

  Source: Yahoo 627

• Position at Google for first four words of title tag on target URL:
  100%

  Source: Google 1

• Age of Domain:
  100%

  Source: Wayback Machine 3936 days old

• Links from domains with .edu TLDs:
  0%

  Source: Yahoo 0

• Links from domains with .gov TLDs:
  0%

  Source: Yahoo 0

• Alexa Rank
  14%

  Source: Alexa 409840

• Domain name visibility A count of results at Google for a search for your domain, showing URL visibility rather than incoming link count.
  36%

  Source: Google 4340

• Internal Link Percent The percentage of pages on the domain that link to the target url. If the target URL is the same as the domain name, this is usually 100%.
  100%

  Source: Yahoo API 100.00%

• Number of search results for URL search at del.icio.us
  17%

  Source: del.icio.us 2

• Listings in DMOZ (ODP)
  47%

  Source: Yahoo 1

• Links found in Wikipedia
  0%

  Source: Yahoo 0

• Google Pagerank of full URL and Domain
  54%

  Source: Google Full URL: 5 Domain: 5

So, from this Page Strength readout I’d conclude that my client needs to:

1. get a lot more links to their domain (what else is new? - almost every site needs more links)

2. The client needs a couple of links from Educational and Goverment Institutions (Google likes Universities and .EDU extensions.)

3. Needs to get more of their pages indexed (actually, it looks like they need more pages to show up, period, in the search engine’s indexes).

4. They need a listing in WikiPedia (and I painted The Death of Wikipedia - so what do know?) and another listing in DMOZ (they already have one).

5. They need to get their pagerank up (most sites do).

I think the Page Strength tool is as much a way to get people to register on SEOMoz (so they can see records of previous searches) as a tool to get information that you can use to improve a page.
