Loading Speed and Related Performance Metrics
Page loading speed directly impacts user experience — research shows that over 25% of visitors leave a website if it takes longer than 3 seconds to load.
Slower websites have a higher bounce rate and lower user engagement, meaning visitors view fewer pages and are less likely to stay.
When a page loads slowly, user trust in the brand decreases, increasing the risk that the visitor will not return or complete a desired action, such as making a purchase.
Loading speed is also important for SEO ranking — search engines like Google consider website performance as one of the factors when determining visibility.
Specifically, analysis shows that even reducing load time by just 100 milliseconds can have a measurable positive impact on conversions and sales.
In one study, reducing load time from 5.5 seconds to 2.5 seconds resulted in an increase in conversion rates of more than 10%.
All of this indicates that speed optimization is not just a technical matter of making a website “fast,” but a key factor in retaining users, increasing engagement, improving SEO rankings, and achieving more successful actions on a website.
Therefore, website owners and online stores should continuously monitor and improve page loading times to avoid losing visitors and revenue.
