Improving the ‘first input delay’ (FID) score on a blog is crucial for enhancing user experience. FID is a Core Web Vital metric that measures the time it takes for a user’s browser to respond after they interact with a website. A low FID score means that the website is responsive and provides a seamless user experience.
FID is an important metric because it captures the user’s first impression of the website. When a user clicks on a website, they expect it to respond quickly. If the website takes too long to respond, the user may become frustrated and leave. Therefore, improving the FID score is essential for reducing bounce rates and increasing engagement on a blog.
There are several strategies that bloggers can use to improve their FID score. Optimizing images, reducing server response time, and minimizing unused JavaScript are some of the effective ways to reduce FID. By implementing these strategies, bloggers can enhance their website’s performance and provide a better user experience.
Understanding First Input Delay
Defining First Input Delay
First Input Delay (FID) is a user-centric performance metric that measures the time between a user’s first interaction with a web page and the response of the page. It is a part of the Core Web Vitals, which are a set of metrics that Google uses to measure user experience on the web. FID measures the responsiveness of a website to user interaction, such as clicking on a link or button or inputting text into a blank field.
The Importance of FID in User Experience
A fast FID score is crucial for a good user experience. Slow FID can lead to frustration and abandonment of the website. Users expect websites to respond quickly to their interactions, and a slow FID score can negatively impact user engagement and retention.
Core Web Vitals and FID
Core Web Vitals are a set of metrics that Google uses to measure user experience on the web. FID is one of the three Core Web Vitals metrics, along with Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS). Websites that have good Core Web Vitals scores are more likely to rank higher in Google search results. Improving FID score can lead to better user experience, higher engagement, and better search engine rankings.
To improve FID score, website owners can optimize their website’s code, reduce the number of third-party scripts, and minimize the impact of long tasks on the main thread. By reducing the time it takes for a website to respond to user interaction, website owners can improve user experience and increase engagement.
Analyzing Your Blog’s Current Performance
To improve the First Input Delay (FID) score on your blog, it is important to first analyze your blog’s current performance. This will help you identify the areas that need improvement and determine the best course of action.
Using Chrome User Experience Report
The Chrome User Experience Report (CrUX) is a public dataset of real-world user experience metrics across millions of websites. It provides valuable insights into how users experience your website, including FID. By analyzing your blog’s CrUX data, you can identify the pages that have poor FID scores and prioritize them for improvement.
To access your blog’s CrUX data, you can use tools like PageSpeed Insights or Chrome UX Report API. These tools will provide you with both field data and lab data, which can help you understand the real-world performance of your website.
Leveraging PageSpeed Insights
PageSpeed Insights is a free tool by Google that analyzes your website’s performance and provides suggestions for improvement. It uses both lab data and field data to provide a comprehensive analysis of your website’s performance.

In conclusion, analyzing your blog’s current performance is the first step towards improving its FID score. By using tools like CrUX, PageSpeed Insights, and Google Search Console, you can gain valuable insights into your website’s performance and identify areas for improvement.
Optimizing JavaScript for Better FID
When it comes to improving the First Input Delay (FID) score of a website, optimizing JavaScript can make a significant difference. Here are some techniques that can help optimize JavaScript for better FID score:
Minifying JavaScript Files
Minifying JavaScript files can help reduce their size, which can lead to faster loading times. Minification involves removing unnecessary characters, such as comments and whitespace, from the code. This can be done manually or by using tools like Babel or Webpack.
Defer Unused JavaScript
Defering unused JavaScript can help improve FID score by reducing the amount of code that needs to be parsed and executed. Defering involves loading JavaScript files after other critical resources have been loaded. This can be done using the defer attribute in the script tag.
Asynchronous Loading of JavaScript
Asynchronous loading of JavaScript can also help improve FID score by allowing the browser to load JavaScript files while other resources are being loaded. This can be done using the async attribute in the script tag.
Avoiding Long JavaScript Tasks
Long JavaScript tasks can cause delays in the browser’s response to user interaction, which can negatively impact FID score. To avoid long JavaScript tasks, it is important to break down complex tasks into smaller, more manageable ones. Code splitting techniques can also be used to divide JavaScript code into smaller chunks that can be loaded as needed.
Code Splitting Techniques
Code splitting techniques involve dividing JavaScript code into smaller chunks that can be loaded as needed. This can help reduce the amount of code that needs to be loaded initially, which can lead to faster loading times and better FID score. Techniques like dynamic imports and lazy loading can be used to implement code splitting.
By optimizing JavaScript using these techniques, website owners can improve their FID score and provide a better user experience to their visitors.
Improving Interaction Readiness
When it comes to improving the First Input Delay (FID) score on a blog, a crucial aspect to focus on is Interaction Readiness. Interaction Readiness refers to how quickly a website responds to user input, and it is a critical factor in providing a positive user experience. Here are some ways to improve Interaction Readiness:
Reducing Total Blocking Time
One of the primary factors that cause poor Interaction Readiness is Total Blocking Time (TBT). TBT is the duration between the first user interaction and the moment when the browser is ready to respond. To reduce TBT, it is essential to minimize the amount of time that the main thread is blocked. The main thread is responsible for executing JavaScript and rendering the page, and it is crucial to optimize its performance.
Optimizing Main Thread Work
To optimize the main thread, it is essential to minimize the amount of JavaScript executed during the critical rendering path. The critical rendering path is the sequence of events that occur between the user’s interaction and the next paint. By reducing the amount of JavaScript executed during this period, you can reduce the TBT and improve Interaction Readiness.
One way to optimize the main thread is by using code splitting. Code splitting involves breaking up the JavaScript code into smaller chunks that can be loaded separately. This approach reduces the amount of JavaScript that needs to be executed during the critical rendering path, which can significantly improve Interaction Readiness.
Effective Use of Web Workers
Another way to optimize the main thread is by using Web Workers. Web Workers are a type of JavaScript that runs in the background, separate from the main thread. By using Web Workers, you can offload some of the work from the main thread, which can significantly improve Interaction Readiness.
To effectively use Web Workers, it is essential to identify tasks that can be performed in the background. For example, tasks that involve heavy calculations or network requests can be performed in Web Workers. By offloading these tasks, you can reduce the workload on the main thread, which can improve Interaction Readiness.
In summary, to improve the FID score on a blog, it is crucial to focus on Interaction Readiness. By reducing TBT, optimizing the main thread, and using Web Workers effectively, you can significantly improve Interaction Readiness and provide a better user experience.
Enhancing Browser Rendering Performance
To improve the First Input Delay (FID) score on a blog, it is important to enhance browser rendering performance. The faster the browser can render the page, the quicker the user can interact with it. Here are some ways to optimize browser rendering performance:
Optimizing HTML and CSS
One way to improve browser rendering performance is to optimize the HTML and CSS code. This can be achieved by reducing the size of the code, minifying it, and removing unnecessary elements. By doing so, the browser can render the page faster, resulting in a better FID score.
Prioritizing Content Loading
Prioritizing content loading is another way to improve browser rendering performance. By loading critical resources first, such as CSS and JavaScript files, the browser can render the page faster. This can be achieved by using the preload attribute in HTML or by using JavaScript to load resources asynchronously.
Efficient Image Handling
Images can often be a bottleneck when it comes to browser rendering performance. To improve FID scores, it is important to handle images efficiently. This can be achieved by compressing images to reduce their file size, using responsive images to ensure that the correct size image is loaded for the device, and lazy loading images so that they are only loaded when they are needed.
By optimizing HTML and CSS, prioritizing content loading, and handling images efficiently, bloggers can improve browser rendering performance and achieve better FID scores.
Addressing Third-Party Impact
One of the most common causes of high First Input Delay (FID) scores is the impact of third-party scripts on your website. These scripts can delay the execution of your site’s own data, leading to longer load times and slower interactivity. However, there are several steps you can take to minimize their impact and improve your FID score.
Managing Third-Party Script Execution
One effective way to manage third-party script execution is to use a script manager. This tool allows you to control which scripts are loaded and when they are executed. By delaying the execution of non-critical scripts until after the main content has loaded, you can ensure that your site’s own data is prioritized and that users can interact with your site more quickly.
Another option is to use asynchronous loading for third-party scripts. This allows the browser to load the script in the background while the rest of the page is being loaded. By the time the user interacts with the page, the script is already loaded and ready to execute, reducing the delay in responsiveness.
Minimizing Impact of Ads
Ads are a common source of third-party scripts, and they can have a significant impact on your site’s FID score. One way to minimize this impact is to use ad blockers or limit the number of ads displayed on your site. Another option is to use lazy loading for ads, which delays the loading of the ad until it is about to be displayed on the screen. This can help reduce the impact of ads on your site’s overall performance.
In addition to these steps, it is also important to regularly review the third-party scripts and code used on your site. Removing any non-critical scripts or code can help reduce the impact of third-party scripts on your site’s performance and improve your FID score. By taking these steps, you can ensure that your site is optimized for FID and provides a faster, more responsive user experience.
User Interaction and Visual Stability
When it comes to improving the “First Input Delay” score on a blog, it’s important to focus on both user interaction and visual stability. By ensuring smooth scrolling and zooming and mitigating cumulative layout shift, bloggers can improve their FID score and provide a better user experience.
Ensuring Smooth Scrolling and Zooming
Smooth scrolling and zooming are important factors in providing a positive user experience. When users interact with a blog, they expect the page to respond quickly and smoothly. If the page takes too long to respond, users may become frustrated and leave the site.
To ensure smooth scrolling and zooming, bloggers should optimize their site’s code and reduce the number of resources that need to be loaded. They can also use lazy loading to delay the loading of non-critical resources until they are needed.
Mitigating Cumulative Layout Shift
Cumulative Layout Shift (CLS) is a metric that measures the amount of unexpected layout shift that occurs during the loading of a page. When a user interacts with a blog, they expect the page to remain stable and not shift unexpectedly. If the page shifts unexpectedly, users may become disoriented and lose their place on the page.
To mitigate CLS, bloggers should optimize their site’s code and reduce the number of resources that need to be loaded. They can also use CSS to reserve space for images and other resources that may cause layout shifts.
By focusing on user interaction and visual stability, bloggers can improve their FID score and provide a better user experience for their readers.
Advanced Techniques and Tools
Improving First Input Delay (FID) score can be challenging, especially if you have already optimized your website using the basic techniques. In this section, we will discuss some advanced techniques and tools that you can use to further optimize your website’s FID score.
Utilizing Polyfills and Transpilation
Polyfills are a set of JavaScript codes that allow modern browsers to emulate the behavior of older browsers. By using polyfills, you can ensure that your website’s interactive elements work properly on older browsers that do not support the latest JavaScript features.
Transpilation is the process of converting modern JavaScript code into a backward-compatible version that can be executed on older browsers. By using transpilation tools like Babel, you can write modern JavaScript code and still ensure that it works on older browsers.
Implementing Server-Side Rendering
Server-side rendering (SSR) is a technique that allows you to render your website’s pages on the server and send the pre-rendered HTML to the client’s browser. By doing this, you can reduce the amount of JavaScript that needs to be downloaded and executed on the client’s browser, which can significantly improve your website’s FID score.
Using Performance Metrics and APIs
Web Performance APIs like the Performance Timing API and the User Timing API can provide you with valuable insights into how your website is performing. By using these APIs, you can measure the time it takes for your website’s interactive elements to respond to user input and identify areas where you can optimize your website’s performance.
The Web Vitals JavaScript library is another tool that you can use to measure your website’s Core Web Vitals, including FID. By using this library, you can get real-time feedback on your website’s performance and identify areas where you can improve.
In conclusion, utilizing advanced techniques and tools like polyfills, SSR, and performance metrics can help you further optimize your website’s FID score. By using these techniques, you can ensure that your website provides a fast and responsive user experience, which can improve your website’s search engine rankings and user satisfaction.
