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.

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.

Replace jQuery and jQuery libraries with more modern code95 KB0.02g
jQuery is a popular and widely-used JavaScript library that simplifies web development by providing a set of tools and functions to interact with HTML documents, handle events, create animations, and make asynchronous HTTP requests.
In the past, jQuery was a very popular choice for web development because it simplified many common tasks and provided a consistent and cross-browser-compatible API. However, with the advancement of modern web technologies and improvements in browser capabilities, the need for jQuery has decreased.
Many modern web frameworks and libraries, such as React and Angular, provide their own set of tools for handling common tasks and interacting with the DOM, making jQuery less necessary in many cases. The Javascript engine in modern browsers have also become more consistent in the feature implementations often eliminating the need for a library like jQuery.
jQuery represents an opportunity because:
- Performance: While jQuery is a powerful and useful library, it can slow down website performance due to its large size and complex code. Modern browsers have also improved their native support for many of the features that jQuery provides, reducing the need for it.
- Maintainability: jQuery code can be difficult to maintain and update, particularly as web technologies evolve and change. This can make it harder for developers to keep up with best practices and standards for web development.
- Accessibility: Some jQuery plugins and features can create accessibility issues, particularly for users who rely on assistive technologies. This can make it harder for people with disabilities to use and access websites.

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.

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.

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.

Tracking scripts
All the tracking scripts on the site generated ~97 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.

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.
