Title	Advice	Score
Avoid slowing down the critical rendering path (avoidRenderBlocking)	The page has 10 blocking requests and 2 in body parser blocking (3 JavaScript and 9 CSS).	70
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://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js https://www.proantic.com/js/sweetalert2.js https://cdn.jsdelivr.net/npm/promise-polyfill@8/dist/polyfill.min.js
Don't scale images in the browser (avoidScalingImages)	The page has 6 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.	40
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.
Have a fast largest contentful paint (largestContentfulPaint)	You can add fetchPriority="high" to the image to increase the load priority in Chrome. The image is lazy loaded using the lazy attribute, you should avoid that on the LCP image.	75
Description: Largest contentful paint is one of Google Web Vitals and reports the render time of the largest image or text block visible within the viewport, relative to when the page first started loading. To be fast according to Google, it needs to render before 2.5 seconds and results over 4 seconds is poor performance.
Avoid CPU Long Tasks (longTasks)	The page has 5 CPU long tasks with the total of 402 ms. The total blocking time is 95 ms and 1 long task before first contentful paint with total time of 107 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.

Long cache headers is good (cacheHeadersLong)	The page has 2 requests that have a shorter cache time than 30 days (but still a cache time).	98
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.

Avoid too many fonts (fewFonts)	The page has 13 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 JavaScript size shouldn't be too big (javascriptSize)	The total JavaScript transfer size is 201.3 kB and the uncompressed size is 582.3 kB. This is quite large.	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?

Try to make the CSS files fit into 14.5 KB.	80
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.

Total page size shouldn't be too big (pageSize)	The page total transfer size is 2.1 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
Description: Use a page description to make the page more relevant to search engines.
