Google Lighthouse Performance
The Google Lighthouse performance score is a metric that measures the speed and performance of a website. It’s an overall score that ranges from 0 to 100 and is generated based on a number of different performance metrics, such as the time it takes for a website to load, the time it takes for a website to become interactive, the size of the resources used by the website, and other factors that impact the user experience.
A high performance score in Google Lighthouse indicates that a website is fast and responsive, which can lead to a better user experience and improved search engine rankings. On the other hand, a low performance score can indicate that a website is slow and unresponsive, and can negatively impact the user experience.

Core Web Vitals
Core Web Vitals are a set of specific factors that Google considers important in a webpage’s overall user experience. Core Web Vitals are made up of three specific page speed and user interaction measurements: Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift.

Tracking scripts
All the tracking scripts on the site generated ~0 B of data
A tracking script is a code snippet designed to track the flow of visitors who visit a website. Media, advertising, and analytics organisations will provide a script to add to your website that sends data directly to their servers. This data can then be used to measure goals and conversions, analyse user behaviour, and influence advertising campaigns.
Consider how much of this data you actually need and use? How often do you review the analytics data, and does this inform genuine change? Are you actively running social media campaigns? Consider pausing or removing tracking scripts that aren’t being actively used.

First Contentful Paint
First Contentful Paint (FCP) is a performance metric that measures the time it takes for the first piece of content to be rendered on the screen when a user navigates to a web page. This content can be any visual element on the page, such as text, images, or a background color.
FCP is important because it directly affects the perceived speed of a website, and can impact user engagement and conversion rates. A faster FCP can lead to a better user experience and improved performance.
Here are a few ways you can optimise your FCP:
- Optimise images: Large, unoptimised images can slow down a page’s FCP. You can optimise images by compressing them, reducing their dimensions, and choosing the right format for each image.
- Minimise HTTP requests: Each resource requested by a web page, such as images, scripts, and stylesheets, requires a separate HTTP request. Minimising the number of HTTP requests can help to reduce the time it takes for a page to render.
- Prioritize critical content: Prioritizing critical content, such as above-the-fold content, can help to ensure that users see something on the screen quickly, even if the rest of the page is still loading.
- Reduce server response time: A slow server response time can significantly impact FCP. Optimizing server-side code and server settings can help to reduce response times and improve FCP.
- Use a performance monitoring tool: There are many tools available that can help you monitor your website’s performance, including FCP. These tools can help you identify performance issues and track your progress as you implement optimizations.

Carbon footprint
The carbon footprint of a website can be calculated by estimating the amount of energy consumed by the data center hosting the website, as well as the energy consumed by users accessing the site. Factors that can influence a website’s carbon footprint include the size of the site, the amount of traffic it receives, and the technology and hosting infrastructure used to host the site.

Sustainable hosting
By hosting this site on a server powered by renewable energy, this page generated ~0grams of CO2 instead of ~0.01grams of CO2.
Sustainable web hosting refers to hosting services that are designed to minimise their impact on the environment and to promote sustainability. This can include using renewable energy sources, reducing waste and emissions, and implementing best practices for energy efficiency.
Sustainable web hosting providers aim to reduce their carbon footprint by using energy-efficient server hardware, data centres, and networking equipment, as well as implementing environmentally friendly policies and practices. For example, some providers may use renewable energy sources, such as wind or solar power, to power their data centres, or they may use high-efficiency cooling systems to reduce energy consumption.

Google Lighthouse Accessibility
The accessibility score in Google Lighthouse is a metric that measures how well a website is designed for users with disabilities. The score ranges from 0 to 100, with higher scores indicating better accessibility.
Google Lighthouse evaluates a website’s accessibility based on a number of different factors, such as the presence of alternative text for images, the use of semantic HTML, the ability to navigate the page using only a keyboard, and the use of appropriate color contrasts.
A high accessibility score in Google Lighthouse indicates that a website is well-designed for users with disabilities and provides an inclusive user experience. On the other hand, a low accessibility score can indicate that a website has barriers that make it difficult or impossible for some users to access and use the content.
In automated testing, this page scored 80% for accessibility on desktop. Keep in mind that automated accessibility testing is not perfect and that manual tests, use case testing, or usability testing should be completed as well.

<html> element does not have a [lang] attribute
If a page doesn't specify a lang attribute, a screen reader assumes that the page is in the default language that the user chose when setting up the screen reader. If the page isn't actually in the default language, then the screen reader might not announce the page's text correctly. Learn more about the lang attribute.

Google Lighthouse Best Practices
Google Lighthouse evaluates a website’s best practices based on a number of different factors, such as the use of HTTPS encryption, the use of efficient caching policies, the implementation of modern web technologies, and the avoidance of deprecated technologies.
A high best practices score in Google Lighthouse indicates that a website is well-designed and follows best practices for web development, which can lead to better performance, security, and accessibility. On the other hand, a low best practices score can indicate that a website has room for improvement in terms of following best practices.

Google Lighthouse SEO
Google Lighthouse evaluates a website’s SEO based on a number of different factors, such as the presence of title and description tags, the use of header tags, the presence of structured data, the use of image alt tags, and the use of crawlable links.
A high SEO score in Google Lighthouse indicates that a website is well-optimized for search engines, which can help to improve its visibility in search results and increase its organic traffic. On the other hand, a low SEO score can indicate that a website has room for improvement in terms of its optimization for search engines.
While a high SEO score can help to improve a website’s visibility in search results, it’s not a guarantee of higher rankings, as search engine algorithms take many other factors into account when determining the ranking of a website.

Security headers to set0/6
HTTP security headers are special HTTP headers that can be added to a website’s response to help improve its security. They are important because they can help to protect a website and its users from various security threats, such as cross-site scripting (XSS) attacks, cross-site request forgery (CSRF) attacks, and other types of malicious activity.
It’s important to note, however, that implementing HTTP security headers is just one aspect of a comprehensive security strategy, and that other measures, such as regular software updates, secure coding practices, and regular security audits, are also important for maintaining a secure website.

Does not use HTTPS
All sites should be protected with HTTPS, even ones that don't handle sensitive data. This includes avoiding mixed content, where some resources are loaded over HTTP despite the initial request being served over HTTPS. HTTPS prevents intruders from tampering with or passively listening in on the communications between your app and your users, and is a prerequisite for HTTP/2 and many new web platform APIs.
