Check your site with The Scrutinizer
If you like keeping an eye on how your site is doing in various areas you probably already use tools like the W3C’s validator services and Alexa’s Traffic Rankings, just to mention a few. But there are many other tools and services that let you study interesting trends, statistics, and technical facts for your site. In fact there are so many that it’s hard to keep track of all of them, which is where The Scrutinizer comes in handy.
The Scrutinizer was created by Rosano Coutinho and is
a service that allows you to analyze, assess and validate any link using various tools and testers on the web.
I spent some time having fun by feeding the URL of this site to most of the services The Scrutinizer links to. The actual value of several services is questionable, and a couple unfortunately seem to be defunct. Of the services that were new to me, my favourite is UrlTrends, which displays ranking and link popularity trends for a page.
Do you know of any other useful online tools or testers?
