HTTP redirects
(Critically important)
This page redirects to "https://molekule.com/"
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 0.46 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 Bootstrap CDN can save bandwidth for Bootstrap front-end component library.
The file size of the HTML document is fine (428 kB).
