Page Speed
Traditional SEO
Page speed is how fast a web page loads for a user, measured from the moment they request the page to when the content is fully visible and interactive, and it is both a direct user experience factor and a Google ranking signal.
Definition
Page speed is how fast a web page loads for a user, measured from the moment they request the page to when the content is fully visible and interactive, and it is both a direct user experience factor and a Google ranking signal. Slow pages frustrate users and increase bounce rates: the share of visitors who leave before interacting. Google has incorporated page speed into its ranking algorithm since 2010 and made it more prominent with the introduction of Core Web Vitals as formal ranking signals.
How It Works
Page speed is affected by several factors: server response time (how fast your hosting infrastructure responds), file sizes (large images and videos slow download times), code efficiency (JavaScript and CSS that blocks page rendering), and geographic distance between the server and the user (a server in Virginia will be slower for users in California than a server with CDN distribution).
Google measures page speed through its PageSpeed Insights tool and through real-world Chrome user experience data. It distinguishes between desktop and mobile speeds, and in the era of mobile-first indexing, mobile page speed is weighted most heavily.
Why It Matters
Users expect pages to load within two to three seconds. Pages that take longer see significantly higher abandonment rates. For a service business, a prospect who bounces before your page loads never became a lead. Slow pages also compound over time: they are crawled less frequently, which means content updates take longer to be indexed and ranked.
Example
A photography studio's website uses full-resolution uncompressed photos on every page, resulting in load times over eight seconds on mobile. After running the images through a compression tool and enabling lazy loading for below-the-fold images, page load drops to under two seconds. Inquiries through the contact form increase the following month, and the site begins ranking for queries it previously could not crack.
