TitleAdviceScore
Inline CSS for faster first render on HTTP/1 (inlineCss)The page has both inline CSS and CSS requests even though it uses a HTTP/2-ish connection. Make sure you are using server push for your CSS files (when your server supports push). If you have many users on slow connections, it can be better to only inline the CSS. Run your own tests and check the waterfall graph to see what happens.95
  • 1.11.3
Avoid extra requests by setting cache headers (cacheHeaders)The page has 17 request(s) that are missing a cache time. Configure a cache time so the browser doesn't need to download them every time. It will save 96.3 kB the next access.0

Total JavaScript size shouldn't be too big (javascriptSize)The total JavaScript transfer size is 189.4 kB and the uncompressed size is 645 kB. This is too much. You need to remove as much as possible.0
Don't use private headers on static content (privateAssets)The page has 2 request(s) with private headers. The main page has a private header. It could be right in some cases where the user can be logged in and served specific content. But if your is static it should never be private. Make sure that the assets really should be private and only used by one user. Else make it cacheable for everyone.90
