Avoid slowing down the critical rendering path (avoidRenderBlocking)	The page has 2 blocking requests and 7 in body parser blocking (8 JavaScript and 1 CSS). There are 2 potentially render blocking requests. You need to verify if they are render blocking: https://www.googletagmanager.com/gtag/js?id=G-CR6HFSTG07 https://www.googletagmanager.com/gtag/js?id=AW-856208209	18
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.

Don't scale images in the browser (avoidScalingImages)	The page has 17 images that are scaled more than 100 pixels. It would be better if those images are sent so the browser don't need to scale them.	0
Description: It's easy to scale images in the browser and make sure they look good in different devices, however that is bad for performance! Scaling images in the browser takes extra CPU time and will hurt performance on mobile. And the user will download extra kilobytes (sometimes megabytes) of data that could be avoided. Don't do that, make sure you create multiple version of the same image server-side and serve the appropriate one.

Avoid using Google Tag Manager. (googleTagManager)	The page is using Google Tag Manager, this is a performance risk since non-tech users can add JavaScript to your page.	0
Description: Google Tag Manager makes it possible for non tech users to add scripts to your page that will downgrade performance.
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 CPU Long Tasks (longTasks)	The page has 14 CPU long tasks with the total of 1.301 s. The total blocking time is 546 ms and 2 long tasks before first contentful paint with total time of 155 ms. However the CPU Long Task is depending on the computer/phones actual CPU speed, so you should measure this on the same type of the device that your user is using. Use Geckoprofiler for Firefox or Chromes tracelog to debug your long tasks.	0
Description: Long CPU tasks locks the thread. To the user this is commonly visible as a "locked up" page where the browser is unable to respond to user input; this is a major source of bad user experience on the web today. However the CPU Long Task is depending on the computer/phones actual CPU speed, so you should measure this on the same type of the device that your user is using. To debug you should use the Chrome timeline log and drag/drop it into devtools or use Firefox Geckoprofiler.

Avoid Frontend single point of failures (spof)	The page has 5 requests inside of the head that can cause a SPOF (single point of failure). Load them asynchronously or move them outside of the document head.	60
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.

Avoid extra requests by setting cache headers (cacheHeaders)	The page has 6 requests that are missing a cache time. Configure a cache time so the browser doesn't need to download them every time. It will save 66 kB the next access.	40
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.

Long cache headers is good (cacheHeadersLong)	The page has 6 requests that have a shorter cache time than 30 days (but still a cache time).	94
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.

Always compress text content (compressAssets)	The page has 2 requests that are served uncompressed. You could save a lot of bytes by sending them compressed instead.	80
Description: In the early days of the Internet there were browsers that didn't support compressing (gzipping) text content. They do now. Make sure you compress HTML, JSON, JavaScript, CSS and SVG. It will save bytes for the user; making the page load faster and use less bandwith.

Total CSS size shouldn't be too big (cssSize)	The total CSS transfer size is 59.9 kB and uncompressed size is 417.5 kB. That is big and the CSS could most probably be smaller.	50
Description: Delivering a massive amount of CSS to the browser is not the best thing you can do, because it means more work for the browser when parsing the CSS against the HTML and that makes the rendering slower. Try to send only the CSS that is used on that page. And make sure to remove CSS rules when they aren't used anymore.

Avoid too many fonts (fewFonts)	The page has 29 font requests. Do you really need them? What value does the fonts give the user?	0
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.

Total image size shouldn't be too big (imageSize)	The page total image size is 6 MB. It's really big. Is the page using the right format for the images? Can they be lazy loaded? Are they compressed as good as they can be? Make them smaller by using https://imageoptim.com/.	50
Description: Avoid having too many large images on the page. The images will not affect the first paint of the page, but it will eat bandwidth for the user.
Total JavaScript size shouldn't be too big (javascriptSize)	The total JavaScript transfer size is 625.7 kB and the uncompressed size is 2.1 MB. This is totally crazy! There is really room for improvement here.	0

Don't use private headers on static content (privateAssets)	The page has 3 requests with private headers. Make sure that the assets really should be private and only used by one user. Otherwise, make it cacheable for everyone.	70
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.
