Title	Advice	Score
Avoid slowing down the critical rendering path (avoidRenderBlocking)	The page has 3 blocking requests and 3 in body parser blocking (3 JavaScript and 3 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	69
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 18 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 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 1.2 kB 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://cdn-images.mailchimp.com/embedcode/horizontal-slim-10_7.css
Long cache headers is good (cacheHeadersLong)	The page has 38 requests that have a shorter cache time than 30 days (but still a cache time).	62
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.

Total CSS size shouldn't be too big (cssSize)	The total CSS transfer size is 71.6 kB and uncompressed size is 401.8 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 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 page size shouldn't be too big (pageSize)	The page total transfer size is 2.4 MB, which is more than the coach limit of 2 MB. That is really big and you need to make it smaller.	0
Description: Avoid having pages that have a transfer size over the wire of more than 2 MB (desktop) and 1 MB (mobile) because that is really big and will hurt performance and will make the page expensive for the user if she/he pays for the bandwidth.

Meta description (metaDescription)	The meta description is too long. It has 159 characters, the recommended max is 155	50

Avoid too many third party requests (thirdParty)	The page do 22% requests to third party domains (11 requests and 881.7 kB). First party is 39 requests and 1.6 MB. The regex .*proantic.* was used to calculate first/third party requests.	50
