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 ~145 KB 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.

Subset large font files219 KB0.049g
Fonts should be subsetted to reduce the file size, improve performance, and reduce emissions. Subsetting a font involves removing any characters that are not needed for a particular use case, resulting in a smaller file size and faster page load times. Some specific reasons why fonts should be subsetted include:
- Reduced file size: Subsetting a font removes any unused characters, which can result in a smaller file size. This can help to reduce the amount of data that needs to be downloaded, leading to faster page load times and lower emissions.
- Improved performance: Fonts that are subsetted are faster to load and render than fonts that are not subsetted. This can help to improve the overall performance of a website, leading to a better user experience.
Overall, subsetting fonts is a good practice for anyone looking to optimize the performance and reduce the emissions of a website of a website.

Convert font files to woff2144 KB
WOFF2 is considered to be the best font format for web use because it provides a good balance of file size and compatibility. Some specific reasons why WOFF2 is a good font format include:
- Small file size: WOFF2 is a compressed font format, which means that it has a smaller file size compared to other font formats like TTF or OTF. This is important for web use because smaller file sizes can help to reduce the amount of data that needs to be downloaded, leading to faster page load times.
- High-quality font rendering: WOFF2 provides high-quality font rendering, making it a good choice for use on the web.
It’s worth noting that WOFF2 is not the only font format that can be used on the web, and there may be cases where other formats like WOFF or TTF are more suitable, depending on the specific requirements of the website. However, for most cases, WOFF2 is considered to be the best font format for web use due to its combination of small file size, good browser support, and high-quality font rendering.

Remove third party font files
Font files should be loaded from the same hosting as the website because
- Increased loading time: Third-party sub-resources, such as scripts, fonts, or images, need to be downloaded from a separate server before they can be displayed on the website. This can increase the overall loading time of the page, leading to a slower user experience.
- Dependence on external servers: The loading of third-party subresources is dependent on the availability and performance of the external servers that host them. If these servers are slow or unavailable, it can result in slow page loading times or even errors.
- Increased risk of security threats: Third-party subresources can introduce security risks to a website, as they can contain malicious code or be used to track user activity.

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.

Sustainable hosting
By hosting this site on a server powered by renewable energy, this page generated ~0.73grams of CO2 instead of ~0.84grams 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.
