Avoid slowing down the critical rendering path (avoidRenderBlocking)The page has 2 blocking requests and 4 in body parser blocking (4 JavaScript and 2 CSS).60
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 15 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.

    • 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)Largest contentful paint is poor 8.256 s. It is in the Google Web Vitals poor range, slower than 4.5 seconds. You can add fetchPriority="high" to the image to increase the load priority in Chrome.0
    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 912 ms. The total blocking time is 642 ms and 1 long task before first contentful paint with total time of 70 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 Frontend single point of failures (spof)The page has 2 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.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.

    • Avoid extra requests by setting cache headers (cacheHeaders)The page has 58 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 1.6 MB 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.

    • Always compress text content (compressAssets)The page has 2 requests that are served uncompressed. You could save a lot of bytes by sending them compressed instead.80
    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.

    Total CSS size shouldn't be too big (cssSize)The total CSS transfer size is 173.8 kB and uncompressed size is 803.3 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 16 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.

    • Total image size shouldn't be too big (imageSize)The page total image size is 1.4 MB. 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 291 kB and the uncompressed size is 1.1 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?

    Meta description (metaDescription)The meta description is too long. It has 162 characters, the recommended max is 15550
    Description: Use a page description to make the page more relevant to search engines.
    Page title (pageTitle)The title is too long by 19 characters. The recommended max is 6050
    Description: Use a title to make the page more relevant to search engines.
    Avoid too many third party requests (thirdParty)The page do more requests to third party domains (68 requests and 2.1 MB) then first party (19 requests and 103.5 kB). The page transfer more bytes from third party domains (2.1 MB) then first party (103.5 kB). The regex .*wildberries.* was used to calculate first/third party requests.0
    Description: Do not load most of your content from third party URLs.
    Avoid unnecessary headers (unnecessaryHeaders)There are 11 responses that sets both a max-age and expires header. There are 10 responses that sets a pragma no-cache header (that is a request header). There are 33 responses that sets a server header. 46
    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.
