HTTP redirects
(Critically important)
The checked page does not redirect to another URL.
HTTP header
(Important)
No X-Powered HTTP header is sent.
This page uses GZip for compressed data transmission.
Performance
(Somewhat important)
The page response time of 0.52 seconds is longer than the recommended limit of 0.4 seconds. A high response time unnecessarily slows down search engine crawling and results in bad user experience as well.
A Content Delivery Network like Google Hosted Libraries can save bandwidth for the JQuery files.
The file size of the HTML document is fine (30 kB).
