What is First Input Delay (FID)?
First Input Delay (FID) is a web development metric that measures the time it takes for a user to interact with a web page and for the page to respond. Specifically, it tracks the delay between the user's first click or tap and when the webpage responds by showing new content or performing an action.
FID has become an important factor in determining website performance because users tend to abandon pages that take too long to respond. FID can be affected by various factors including server response times, unoptimized code, slow third-party scripts, large images and more.
In order to improve website performance and provide better user experience, developers should keep FID as low as possible which means optimizing their pages for faster response times.
The impact of high FID on your website
If your website has high FID, it can negatively affect your business by reducing conversions rates, increasing bounce rates and lowering organic rankings. This happens because users are less likely to engage with web pages that take too long to load or respond. Users might lose interest in waiting for a site's page load or functionality causing them leaving immediately from there without exploring further.
By committing resources towards improving their sites' FIDs, businesses will see increased engagement from users leading towards greater sales revenue, improved customer satisfaction rating along with higher search engine rankings - all of which ultimately lead towards business growth!
Optimization techniques for reducing FID
There are several optimization techniques that can be used to reduce FID. One such technique is by reducing the amount of third-party scripts running on web pages which can affect performance dramatically.
In summary, adopting these techniques will help developers deliver faster web experiences thereby lowering FID, improving user engagement rates and boosting overall website performance!
