invalid object

[theniks1]

I downloaded this script which sounds amazing and I installed it on my local xampp server but I keep getting this error
"Notice: Undefined index: http://www.google.com in C:\xampp\htdocs\xampp\seo\examples\example-1.php on line 7
Invalid Object > Requires an URL."
I am sure i am making some stupid mistake but it will be great if some one can help me with this
Regards

$url = new SEOstats('http://nytimes.com');
