It measures the time between the first interaction a user makes (e.g., clicking a link or CTA button) and the browser&#8217;s response to that interaction. It reflects how interactive and responsive a website is in users&#8217; eyes. A lower First Input Delay (FID) indicates a smooth experience, while a higher FID or responsiveness indicates poor optimization or lag.&nbsp;<\/p>\n\n\n\n<p>For example, if you click a \u201cBuy Now\u201d button and it takes more than the ideal time to respond, that delay shows poor FID.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Benefits of Good FID<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Reduces bounce rates<\/li>\n\n\n\n<li>Improves user experience<\/li>\n\n\n\n<li>Higher SEO rankings<\/li>\n\n\n\n<li>Polish website performance<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion&nbsp;<\/h2>\n\n\n\n<p>First Input Delay measures the time it takes a website to respond to a user&#8217;s actions.
