HTTP redirects
(Critically important)
This page redirects to "https://echo.epa.gov/"
HTTP header
(Important)
The web server version is sent within the HTTP header.
The X-powered header is sent within the response header. (unnecessary)
The web server transmits the web page (HTML) in compressed form.
Performance
(Somewhat important)
The page response time of 0.76 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.
The file size of the HTML document is fine (65 kB).
