TitleAdviceScore
Inline CSS for faster first render (inlineCss)The page has both inline CSS and CSS requests even though it uses a HTTP/2-ish connection. 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
  • 3.3.1
Avoid extra requests by setting cache headers (cacheHeaders)The page has 19 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 100.6 kB the next access.0

Total JavaScript size shouldn't be too big (javascriptSize)The total JavaScript transfer size is 213.1 kB and the uncompressed size is 731.9 kB. This is quite large. 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 asset is static it should never be private. Make sure that the assets really should be private and only used by one user. Otherwise, make it cacheable for everyone.90
