Title	Advice	Score
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 extra requests by setting cache headers (cacheHeaders)	The page has 5 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 90.1 kB the next access.	50
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 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: URL Transfer size Content size https://www.antiquites-en-france.com/ 5.4 KB 5.3 KB
The favicon should be small and cacheable (favicon)	The favicon size is 12 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: https://www.antiquites-en-france.com/__ovh/common/img/favicon.ico
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.

Avoid missing and error requests (responseOk)	The page has 1 error response. The page has 1 response with code 404.	90
Description: Your page should never request assets that return a 400 or 500 error. These requests are never cached. If that happens something is broken. Please fix it.

Declare a doctype in your document (doctype)	The page is missing a doctype. Please use <!DOCTYPE html>.	0
Description: The <!DOCTYPE> declaration is not an HTML tag; it is an instruction to the web browser about what version of HTML the page is written in.
Meta description (metaDescription)	The page is missing a meta description.	0
Description: Use a page description to make the page more relevant to search engines.
Avoid unnecessary headers (unnecessaryHeaders)	There are 6 responses that sets both a max-age and expires header. There are 6 responses that sets a pragma no-cache header (that is a request header). There are 6 responses that sets a server header.	82
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.

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: https://www.antiquites-en-france.com/
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/.
