HTTP redirects
(Critically important)

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 0.61 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.
