(Important)
No X-Powered HTTP header is sent.
The web server transmits the web page (HTML) in compressed form.

(Somewhat important)
The page response time of 0.72 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.
