When we analyze a website with Lighthouse, Google measures 5 different timings, each with a different weight in the final score. Below we explain what each metric means and, afterward, why sliders tend to be a problem both for speed and usability.<\/p>\n
This is the moment the user first sees something on screen. If it takes too long, the user thinks the site isn’t loading and leaves.<\/p>\n
Measures how quickly all the content is visually “painted.” It’s the overall speed at which the page appears.<\/p>\n
The largest element on screen (usually an image or the main text block). It’s the metric most associated with “the page has finished loading.”<\/p>\n
The most important one. The time the browser spends busy executing code that isn’t responding to user clicks or taps. This is where heavy JavaScript shows the most.<\/p>\n
Measures whether elements “jump” while the page loads. Has it ever happened that you go to click and the button moves, making you miss it or click somewhere else? That’s CLS.<\/p>\n
There’s a solid technical reason: sliders usually add extra JavaScript right at the top of the site, exactly where it most affects FCP and LCP (on top of images or videos), slowing down precisely the moment users notice the most.
\nBut the problem isn’t just about speed, it’s also about user behavior.<\/p>\n
In practice, no visitor waits passively for 3, 5, or 7 seconds for the slider to change image or video. What they do, in the first 1-3 seconds, is read the headline at the top and then, just like on social media (out of habit), scroll down.
\nThat means one clear thing: the second piece of information on the page is just as important as the first. It makes no sense to concentrate all conversion efforts only at the top (hero + slider) if the user is already scrolling down.<\/p>\n
Instead of locking attention at the top with a slider, it’s better to use a fixed image: engagement and emotional impact are conveyed just as well, without penalizing loading speed. And keep pace with the scroll.
\nEach block on the page should have its own useful CTA, designed to convert at that exact point in the journey.
