Performance advice (54)

TitleAdviceScore
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.
Offenders:
Avoid slowing down the critical rendering path (fastRender)The page has 17 render blocking CSS requests and 15 blocking JavaScript requests inside of head.0
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 or use server push for really fast rendering and a short rendering path.
Offenders:
Inline CSS for faster first render (inlineCss)The page has both inline styles as well as it is requesting 17 CSS files inside of the head. Let's only inline CSS for really fast render.90
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.
Offenders:
Avoid CPU Long Tasks (longTasks)The page has 14 CPU long tasks with the total of 2128 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 Task.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.

Avoid Frontend single point of failures (spof)The page has 13 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.70
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 14 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 99 kB the next access.0
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 59 requests that have a shorter cache time than 30 days (but still a cache time).41
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:
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:
Total CSS size shouldn't be too big (cssSize)The total CSS transfer size is 134.3 kB and uncompressed size is 651.1 kB. 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.
The favicon should be small and cacheable (favicon)The favicon size is 15.1 kB bytes. That's quite big, can you make it smaller? The favicon has no cache time. 0
Description: It is easy to make the favicon big but please avoid doing that, because every browser will then perform an unnecessarily large download. And make sure the cache headers are set for a long time for the favicon. It is easy to miss since it's another content type.
Offenders:
Avoid too many fonts (fewFonts)The page has 2 font requests. Do you really need them? What value does the fonts give the user?80
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 image size shouldn't be too big (imageSize)The page total image size is 5 MB. It's really big. Is the page using the right format for the images? 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 443.1 kB and the uncompressed size is 1.2 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?
Avoid using incorrect mime types (mimeTypes)The page has 4 misconfigured mime types. 96
Description: It's not a great idea to let browsers guess content types (content sniffing), in some cases it can actually be a security risk.
Offenders:
Make each CSS response small (optimalCssSize)https://static.aecdaily.com/fontawesome_pkgs/fontawesome-pro-6.5.2-web/css/all.min.css size is 102.5 kB (102458) and that is bigger than the limit of 14.5 kB. Try to make the CSS files fit into 14.5 KB.90
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 6.9 MB, which is more than the coach limit of 2 MB. That is insane 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.
Don't use private headers on static content (privateAssets)The page has 2 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.80
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.

Best practice advice (86)

TitleAdviceScore
Declare the language code for your document (language)The page is missing a language definition in the HTML tag. Define it with <html lang="YOUR_LANGUAGE_CODE">0
Description: According to the W3C recommendation you should declare the primary language for each Web page with the lang attribute inside the <html> tag https://www.w3.org/International/questions/qa-html-language-declarations#basics.
Cumulative Layout Shift (layoutShift)You have elements that shift. You should manually check the filmstrip or video and check if it will affect the user.79
Description: Cumulative Layout Shift measures the sum total of all individual layout shift scores for every unexpected layout shift that occurs during the entire lifespan of the page. A layout shift occurs any time a visible element changes its position from one rendered frame to the next.
Offenders:
Avoid Unnecessary Headers (unnecessaryHeaders)There are 3 responses that sets a p3p header. There are 7 responses that sets both a max-age and expires header. There are 9 responses that sets a pragma no-cache header (that is a request header). There are 80 responses that sets a server header. 1
Description: Do not send headers that you don't need. We look for p3p, cache-control and max-age, pragma, server and x-frame-options headers. Have a look at Andrew Betts - Headers for Hackers talk as a guide https://www.youtube.com/watch?v=k92ZbrY815c or read https://www.fastly.com/blog/headers-we-dont-want.

Privacy advice (68)

TitleAdviceScore
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/.
Offenders:
Set a permission policy header that opt out your users being tracked in Chrome by FLoC. (disableFLoCHeader)Set a permission policy header that opt out Chrome for tracking what your users do on your site.0
Description: Googles new tracking method is called Federated Learning of Cohorts (FLoC) and it groups you based on your interests and demographics, derived from your browsing history, to enable creepy advertising and other content targeting without third-party cookies. You can avoid that by setting a Permissions-Policy header with the value of interest-cohort=(). See https://www.eff.org/deeplinks/2021/03/googles-floc-terrible-idea.
Offenders:
Avoid using Google reCAPTCHA (googleReCaptcha)You share your user data with Google since you use Google reCAPTCHA.0
Description: You should avoid using Google reCAPTCHA since it will share your users information with Google.
Offenders:
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/.
Offenders:
Set a strict transport header to make sure the user always use HTTPS. (strictTransportSecurityHeader)A strict transport header is set but miss out on setting includeSubDomainsThe max age is lower than six months. Increase it to get a better score.70
Description: The HTTP Strict-Transport-Security response header (often abbreviated as HSTS) lets a web site tell browsers that it should only be accessed using HTTPS, instead of using HTTP. https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Strict-Transport-Security.
Do not share user data with third parties. (thirdPartyPrivacy)The page has 3% requests that are 3rd party (2 requests with a size of 279 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 1 utility request and uses 1 utility tool. The page do 2 survelliance requests and uses 2 survelliance tools.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.

Layout shift

The elements that have shifted place is highlighted in the image (that have a higher value than 0.01). If the element shifted outside of the viewport, you will not see it there. It can be hard to understand what content that has shifted, if that's the case, checkout the video or the filmstrip of the run.

Sustainable Web

We know that using the internet means using electricity, and because most of that electricity comes from fossil fuels, it means that more data we send, the more fossil fuels we end up burning.

This is terrible news for the climate, and building a sustainable web is the 9th of the W3C's Ethical Web Principles.

If you build for the web, much of what you know about making sites faster and more accessible also makes them greener. If you're interested in learning more, you can find out at The Green Web Foundation.

Use--sustainable.pageViewsto configure the number of page views and calculate total CO2 emission.
