Seomoz designed page strength to give a summary of factors given to the tested url

The factors that go into page strength are:

• Links pointing to full URL - This is the number of links that are pointing to your page. If you were viewing a report for http;//www.example.com/my-page, this would be the number of incoming links to that exact URL. This factor is an indication of link strength to your specific URL.
• Links pointing to domain - This is the number of links that are pointing to your domain. If you were viewing a report for http;//www.example.com/my-page, this would be the number of incoming links to www,example.com. This factor is an indication of link strength across your entire domain.
• Position at Google for the first four words of title tag - This is the position in the search results for the first four words of the HTML title tag on your page. For instance, the title tag of SEOmoz's home page is "Read SEOmoz, Rank Better" and we rank #1 for that term. This factor is a good indication of how well your page is performing at the search engines for a term that is relatively unique. If it's not ranking it may be possible that your site is experiencing a penalty, spidering issue, or is new and has not earned search engine "trust" yet. We chose the first 4 words because using the entire title tag was usually too unique and would almost always report a site ranking in the top 10. Using less than 4 words from the title tag would was too broad and most sites would typically be absent from the serps. After a bit of research, 4 words seem to be the happy medium between the two that returned the most accurate results.
• Age of Domain - This is a measurement of how long your domain has been registered: the older the better. Older sites are considered more trusted by the search engines and typically have an easier time ranking for competitive terms.
• Links from domains with .edu TLDs - This is the number of links to your page that are from .edu websites ( such as www,harvard.edu) . Search engines consider these more valuable than traditional .com or .net links.
• Links from domains with .gov TLDs - Same as above
• Alexa Rank - In short: the lower your Alexa Rank, the better. Alexa assigns a score to every website that is an indication of popularity. It computes this score by analyzing the Web usage of millions of Alexa Toolbar users. Although somewhat unreliable in many sectors, the Alexa rank is the most reliable when comparing websites is similar sectors. For example: comparing the Alexa rank of a website about web design versus a site about kittens would not be an accurate comparison. However, comparing the Alexa rank of a website about web design versus a site about web programming would be.
• Domain name visibility - If your website is www,example.com, the domain name visibility is the number of results that are returned at Google for a search for "www.example.com." (in quotes). Adding the quotes changes the search query to show pages across the web that have mentioned www,example.com, without quotes it would simply return a list of pages that Google has indexed from www,example.com. This is a good measurement of how visible your domain is: are people talking about your domain? Is it getting mentioned on forums, blogs, etc?
• Internal link percent - This is the percent of pages on your domain that link to your target URL. For instance, lets suppose your target URL was www,example.com/my-page. The internal link percent would be the percentage of links on www,example.com that point to www,example.com/my-page. It is a way of measuring the importance of a URL on a domain. If the URL you are fetching a Page Strength report is for the homepage of your website the internal link percent is usually 100% because almost all pages link back to the homepage.
• Number of links according to Technorati - Technorati is a blog search engine, this is the number of sites Technorati has found that are linking to your URL. Although weighted more toward blogs, Technorati counts links much quicker than Google and provides a better number of links initially than Google or Yahoo.
• Number of search results for URL search at del.icio.us - del.icio.us is a social bookmarking site where users collaboratively share websites. We use the number of people that have bookmarked your URL as an indication of popularity.
• Listings in DMOZ (ODP) - Although it definitely doesn't pass the value it once did, links a link from DMOZ is still considered powerful.
• Links found in Wikipedia - Wikipedia links are valuable - this is the number of links from Wikipedia to your target URL.
• Google PageRank of full URL and Domain - Although inaccurate and infrequently updated, Google PageRank still offers some indication of the strength of a URL.
