The Impact of Core Web Vitals on SEO: A Real-life Example

Sarah’s Story

Sarah runs an e-commerce website selling handmade jewelry. After noticing a drop in website traffic and sales, she decided to investigate. Upon analyzing her website’s Core Web Vitals, she discovered that the Largest Contentful Paint (LCP) was well above the recommended threshold, leading to slow loading times.

The Effects

As a result of the slow loading times, potential customers were leaving her website before the products could even load properly, impacting both user experience and conversion rates. Sarah realized that Google’s emphasis on Core Web Vitals was directly impacting her website’s SEO performance.

The Solution

Sarah immediately took action to optimize her Core Web Vitals by compressing images, minifying CSS and JavaScript files, and leveraging browser caching. After implementing these changes, she saw a significant improvement in her website’s loading performance, resulting in higher user satisfaction and increased sales.

This real-life example illustrates the tangible impact of Core Web Vitals on SEO and highlights the crucial role they play in enhancing the overall performance of a website.

When asked in a Google SEO office-hours video whether internal linking was still important for SEO, John Mueller said: “Internal links do this by directing the flow of PageRank around your site. Even though the PageRank toolbar disappeared in 2016, PageRank is still a signal that Google uses.”
