the Page Strength tool, which is an elaborate, marketed way of displaying very common data as if it were being analyzed (which it is not), now carries a nifty pop-over pushing the premium membership option that must be bypassed before you can use the 'tool'. then, when the data retrieval script left out some of the most important metrics (age of domain, pagerank for instance) i followed the advice at the bottom of the page "If your report contains missing data, try refreshing it." Guess what it read:
"Due to hardware constraints we are temporarily limiting this feature to our premium members".
