(Important)
The HTML page should be transferred using GZip compression.
No X-Powered HTTP header is sent.
Performance

The page response time of 0.84 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.
