| Avoid slowing down the critical rendering path (avoidRenderBlocking) | The page has 6 blocking requests and 3 in body parser blocking (5 JavaScript and 4 CSS). There are 2 potentially render blocking requests. You need to verify if they are render blocking: https://www.google.com/recaptcha/api.js?hl=fr https://www.googletagmanager.com/gtag/js?id=G-YP51KSLLWR | 48 | ||||||||||||||||||||||||||||||
| 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: | ||||||||||||||||||||||||||||||||
| Don't scale images in the browser (avoidScalingImages) | The page has 1 image 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. | 90 | ||||||||||||||||||||||||||||||
| 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. | ||||||||||||||||||||||||||||||||
| Offenders: | ||||||||||||||||||||||||||||||||
| 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. | ||||||||||||||||||||||||||||||||
| Have a fast largest contentful paint (largestContentfulPaint) | You can add fetchPriority="high" to the image to increase the load priority in Chrome. | 95 | ||||||||||||||||||||||||||||||
| 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 3 CPU long tasks with the total of 245 ms. The total blocking time is 38 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. | 40 | ||||||||||||||||||||||||||||||
| 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. | ||||||||||||||||||||||||||||||||
| Offenders: | ||||||||||||||||||||||||||||||||
| 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: | ||||||||||||||||||||||||||||||||
| Avoid extra requests by setting cache headers (cacheHeaders) | The page has 3 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 34.3 kB the next access. | 70 | ||||||||||||||||||||||||||||||
| 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: | ||||||||||||||||||||||||||||||||
| Long cache headers is good (cacheHeadersLong) | The page has 36 requests that have a shorter cache time than 30 days (but still a cache time). | 64 | ||||||||||||||||||||||||||||||
| 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. | ||||||||||||||||||||||||||||||||
| Offenders: | ||||||||||||||||||||||||||||||||
| Total CSS size shouldn't be too big (cssSize) | The total CSS transfer size is 114.1 kB and uncompressed size is 480.7 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. | ||||||||||||||||||||||||||||||||
| Offenders: | ||||||||||||||||||||||||||||||||
| Avoid too many fonts (fewFonts) | The page has 8 font requests. Do you really need them? What value does the fonts give the user? | 20 | ||||||||||||||||||||||||||||||
| 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. | ||||||||||||||||||||||||||||||||
| Offenders: | ||||||||||||||||||||||||||||||||
| Total JavaScript size shouldn't be too big (javascriptSize) | The total JavaScript transfer size is 599.3 kB and the uncompressed size is 1.6 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? | ||||||||||||||||||||||||||||||||
Offenders:

| Make each CSS response small (optimalCssSize) | https://www.proantic.com/css/A.sweetalert2-v1-2.css+carrousel-09.css+fontawesome.min.css+regular.min.css+thin.min.css+sharp-solid.min.css+light.min.css,Mcc.iqUiudq9r-.css.pagespeed.cf.ioXOhovDxv.css size is 39.6 kB (39566) and that is bigger than the limit of 14.5 kB. https://www.gstatic.com/recaptcha/releases/xds0rzGrktR88uEZ2JUvdgOY/styles__ltr.css size is 42.6 kB (42566) and that is bigger than the limit of 14.5 kB. 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. | ||||||||||||||||||||||||||||||||
Offenders:
| ||||||||||||||||||||||||||||||||
| Total page size shouldn't be too big (pageSize) | The page total transfer size is 2.2 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. | ||||||||||||||||||||||||||||||||
| Offenders: | ||||||||||||||||||||||||||||||||
| Don't use private headers on static content (privateAssets) | The page has 4 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. | 60 | ||||||||||||||||||||||||||||||
| 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. | ||||||||||||||||||||||||||||||||

| 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/. | ||

| Set a referrer-policy header to make sure you do not leak user information. (referrerPolicyHeader) | Set a referrer-policy header to make sure you do not leak user information. | 0 |
| Description: Referrer Policy is a new header that allows a site to control how much information the browser includes with navigations away from a document and should be set by all sites. https://scotthelme.co.uk/a-new-security-header-referrer-policy/. | ||

| Do not share user data with third parties. (thirdPartyPrivacy) | The page has 35% requests that are 3rd party (19 requests with a size of 841.4 kB). The page also have request to companies that harvest data from users and do not respect users privacy (see https://en.wikipedia.org/wiki/Surveillance_capitalism). The page do 5 utility requests and uses 1 utility tool. The page do 17 survelliance requests and uses 4 survelliance tools. The page do 1 tag-manager request and uses 1 tag-manager tool. The page do 1 marketing request and uses 1 marketing tool. | 0 |
| Description: Using third party requests shares user information with that third party. Please avoid that! The project https://github.com/patrickhulce/third-party-web is used to categorize first/third party requests. | ||
