informative!! i used TheWebPole.com to check my page rank of my site. they keep track of the ranking of the sites through their search engine visibility tool
Normally when I view the source code in the browser, clicking on a link, takes me to that page or displays the source such as the CSS or Javascript.
Checking on further links down the page I tried "http://ninjarite.com/" and got the following message:
We're in the process of setting up our new server, we'll be right back!
I presume that Google's API Key has not been registered for the new server.
I use historical pagerank checker tool, so i can compare new stats with the olds. I use two similar site to collect information (pagerank, alexa stats, facebook and twitter mention count, site speed check) http://www.historicalsiteinfo.com and http://www.topwebsitecheck.com
