Fixing FID Issues

Understanding FID (First Input Delay)

First Input Delay (FID) is a crucial metric in Google’s Core Web Vitals, measuring the time from when a user first interacts with your site to the time when the browser responds to that interaction. A good FID score is less than 100 milliseconds.

Checking FID on Shopify

  1. Use Google PageSpeed Insights: Go to Google PageSpeed Insights and enter your Shopify store URL. The tool will provide a detailed report, including FID metrics.
  2. Shopify Apps: Consider using Shopify apps like PageSpeed Optimizer to help analyze and improve your FID score.

Checking FID on WordPress (WooCommerce)

  1. Use Google PageSpeed Insights: Similar to Shopify, enter your WooCommerce store URL in Google PageSpeed Insights to get a detailed report.
  2. Plugins: Use plugins like WP Rocket or W3 Total Cache to optimize your site and improve FID.

Improving FID

  • Minimize JavaScript: Reduce the impact of third-party code and optimize your JavaScript to ensure faster interaction times.
  • Use Browser Caching: Implement browser caching to store static files and reduce load times.
  • Optimize Server Response Time: Ensure your server is optimized to handle requests quickly.

By regularly monitoring and optimizing your FID, you can significantly improve user experience and potentially boost your search engine rankings.
