Avoid slowing down the critical rendering path (avoidRenderBlocking)	The page has 11 blocking requests and 4 in body parser blocking (4 JavaScript and 11 CSS). There are 1 potentially render blocking requests. You need to verify if it is render blocking: https://www.googletagmanager.com/gtag/js?id=G-YP51KSLLWR	59
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.

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.
Avoid CPU Long Tasks (longTasks)	The page has 11 CPU long tasks with the total of 1.272 s. The total blocking time is 662 ms and 2 long tasks before first contentful paint with total time of 160 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 doing redirects (assetsRedirects)	The page has 1 redirect. 1 request are from other domains, it could be 3rd-party assets doing unnecessary redirects. :(	90
Description: A redirect is one extra step for the user to download the asset. Avoid that if you want to be fast. Redirects are even more of a showstopper on mobile.
Offenders: https://googleads.g.doubleclick.net/pagead/id
Avoid extra requests by setting cache headers (cacheHeaders)	The page has 4 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 57.9 kB the next access.	60
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 3 requests that have a shorter cache time than 30 days (but still a cache time).	97
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 1 request that are served uncompressed. You could save a lot of bytes by sending them compressed instead.	90
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.
Offenders: URL Transfer size Content size https://www.googletagmanager.com/gtag/js?id=G-YP51KSLLWR 149.5 KB 432.8 KB
Total CSS size shouldn't be too big (cssSize)	The total CSS transfer size is 173.6 kB and uncompressed size is 1.2 MB. That is big and the CSS could most probably be smaller.	0
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 9 font requests. Do you really need them? What value does the fonts give the user?	10
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 782.6 kB. 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 1 MB and the uncompressed size is 3.2 MB. This is totally crazy! There is really room for improvement here.	0
Description: A lot of JavaScript often means you are downloading more than you need. How complex is the page and what can the user do on the page? Do you use multiple JavaScript frameworks?
