Title	Advice	Score
Avoid slowing down the critical rendering path (avoidRenderBlocking)	The page has 5 blocking requests and 2 in body parser blocking (2 JavaScript and 5 CSS).	80
Description: The critical rendering path is what the browser needs to do to start rendering the page. Every file requested inside of the head element will postpone the rendering of the page, because the browser need to do the request. Avoid loading JavaScript synchronously inside of the head (you should not need JavaScript to render the page), request files from the same domain as the main document (to avoid DNS lookups) and inline CSS for really fast rendering and a short rendering path.
Offenders: https://www.proantic.com/magazine/wp-content/themes/olsen-light/js/scripts.js,qv....jm.YPk7tHUcXX.js https://stats.wp.com/e-202511.js
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
Description: In the early days of the Internet, inlining CSS was one of the ugliest things you can do. That has changed if you want your page to start rendering fast for your user. Always inline the critical CSS when you use HTTP/1 and HTTP/2 (avoid doing CSS requests that block rendering) and lazy load and cache the rest of the CSS. It is a little more complicated when using HTTP/2. Does your server support HTTP push? Then maybe that can help. Do you have a lot of users on a slow connection and are serving large chunks of HTML? Then it could be better to use the inline technique, becasue some servers always prioritize HTML content over CSS so the user needs to download the HTML first, before the CSS is downloaded.
Avoid Frontend single point of failures (spof)	The page has 1 request inside of the head that can cause a SPOF (single point of failure). Load them asynchronously or move them outside of the document head.	90
Description: A page can be stopped from loading in the browser if a single JavaScript, CSS, and in some cases a font, couldn't be fetched or is loading really slowly (the white screen of death). That is a scenario you really want to avoid. Never load 3rd-party components synchronously inside of the head tag.
Offenders: https://fonts.googleapis.com/css...oogleapis.com/css
Avoid extra requests by setting cache headers (cacheHeaders)	The page has 1 request that are missing a cache time. Configure a cache time so the browser doesn't need to download them every time. It will save 177 B the next access.	90
Description: The easiest way to make your page fast is to avoid doing requests to the server. Setting a cache header on your server response will tell the browser that it doesn't need to download the asset again during the configured cache time! Always try to set a cache time if the content doesn't change for every request.
Offenders: https://pixel.wp.com/g.gif...ixel.wp.com/g.gif
Long cache headers is good (cacheHeadersLong)	The page has 10 requests that have a shorter cache time than 30 days (but still a cache time).	90
Description: Setting a cache header is good. Setting a long cache header (at least 30 days) is even better beacause then it will stay long in the browser cache. But what do you do if that asset change? Rename it and the browser will pick up the new version.

Avoid too many fonts (fewFonts)	The page has 5 font requests. Do you really need them? What value does the fonts give the user?	50
Description: How many fonts do you need on a page for the user to get the message? Fonts can slow down the rendering of content, try to avoid loading too many of them because worst case it can make the text invisible until they are loaded (FOIT—flash of invisible text), best case they will flicker the text content when they arrive.

Make each CSS response small (optimalCssSize)	https://www.proantic.com/magazine/wp-includes/css/dist/block-library/A.style.min.css,qver=6.7.pagespeed.cf.-GTKN38myC.css size is 15.9 kB (15897) and that is bigger than the limit of 14.5 kB. Try to make the CSS files fit into 14.5 KB.	90
Description: Make CSS responses small to fit into the magic number TCP window size of 14.5 KB. The browser can then download the CSS faster and that will make the page start rendering earlier.
Offenders: URL Transfer size Content size https://www.proantic.com/magazine/wp-includes/css/dist/block-library/A.style.min...cf.-GTKN38myC.css 15.5 KB 111.9 KB
Don't use private headers on static content (privateAssets)	The page has 1 request with private headers. Make sure that the assets really should be private and only used by one user. Otherwise, make it cacheable for everyone.	90
Description: If you set private headers on content, that means that the content are specific for that user. Static content should be able to be cached and used by everyone. Avoid setting the cache header to private.

Avoid too many third party requests (thirdParty)	The page do 48% requests to third party domains (10 requests and 281.8 kB). First party is 11 requests and 110.4 kB. The page transfer more bytes from third party domains (281.8 kB) then first party (110.4 kB). The regex .*proantic.* was used to calculate first/third party requests.	0
Description: Do not load most of your content from third party URLs.
Avoid unnecessary headers (unnecessaryHeaders)	There are 19 responses that sets both a max-age and expires header. There are 21 responses that sets a server header.	60
Description: Do not send headers that you don't need. We look for p3p, cache-control and max-age, pragma, server and x-frame-options headers.

Use a good Content-Security-Policy header to make sure you you avoid Cross Site Scripting (XSS) attacks. (contentSecurityPolicyHeader)	Set a Content-Security-Policy header to make sure you are not open for Cross Site Scripting (XSS) attacks. You can start with setting a Content-Security-Policy-Report-Only header, that will only report the violation, not stop the download.	0
Description: Content Security Policy is delivered via a HTTP response header, and defines approved sources of content that the browser may load. It can be an effective countermeasure to Cross Site Scripting (XSS) attacks and is also widely supported and usually easily deployed. https://scotthelme.co.uk/content-security-policy-an-introduction/.
