Optimize Your Shopify Store for Speed and Conversion: Reduce Largest Contentful Paint (LCP)
Is your Shopify store sluggish? Are you losing potential customers due to slow loading times? Optimizing your store’s Largest Contentful Paint (LCP) can significantly improve user experience, boost conversions, and elevate your search ranking.
The specific largest content element may vary depending on the page and its content. In a typical Shopify store, examples of elements that can contribute to LCP include product images, banners, or hero images.
- 1. LCP is one of the Core Web Vital
- 2. GSI score has 25% weightage for LCP
- 3. LCP of less than 2.5 seconds is considered good to pass core web vitals
LCP measures the time it takes for the largest element on your Shopify store page to render within the viewport, essentially the perceived loading speed for your users. A slow LCP can result in:
- Increased bounce rates: Studies show that 70% of online shoppers expect a page to load within 2 seconds. Every additional second of delay increases the likelihood of users abandoning your store.
- Decreased conversion rates: A 1-second LCP delay can lead to a 7% drop in conversions, directly impacting your bottom line.
- Lower search ranking: Google prioritizes LCP in its Core Web Vitals, a key factor in determining a website’s search ranking.
