A fast website keeps visitors happy and ranks higher on Google. Here is how to make sure your site loads quickly. Your hosting choice plays a big role too.
Website speed directly affects whether people stay on your site or leave.
of visitors leave a site that takes longer than 3 seconds to load
increase in people leaving when load time goes from 1 second to 3 seconds
Google uses page speed as a ranking factor. Faster sites appear higher in search results
Google measures three things about your website speed. Here is what they mean in plain English.
Largest Contentful Paint
How long it takes for the biggest thing on your page (usually a hero image or heading) to appear.
Interaction to Next Paint
How quickly your site responds when someone clicks a button, taps a link, or types in a form.
Cumulative Layout Shift
How much stuff jumps around while the page loads. Ever try to click something and it moves? That is CLS.
Images are usually the biggest files on a website. Optimizing them is the fastest way to speed up your site.
Tell your AI tool to use WebP or AVIF instead of PNG or JPEG. These formats are much smaller with the same quality.
A 4000px wide photo is overkill for a website. Tell your AI tool to resize images to the actual display size.
Images below the fold (not visible when the page first loads) should only load when the visitor scrolls to them.
If you are using Next.js, tell your AI tool to use the built-in Image component. It handles optimization automatically.
"Audit my website for image optimization. Convert all images to WebP format, add lazy loading to images below the fold, and resize any images that are larger than they need to be."
Tell your AI tool to do these things. Each one makes your site faster.
"Go through my website and apply all performance best practices: optimize images, add lazy loading, remove unused code, and make sure all images have width and height attributes."
Copy-paste these prompts into your AI tool to apply what you just learned.
FULL PERFORMANCE AUDIT
"Audit my Next.js app for performance issues. Check for large images, unused JavaScript, slow API calls, and missing lazy loading. Suggest specific fixes."
OPTIMIZE IMAGES
"Optimize the images on my site. Convert them to WebP, add proper width/height attributes, and implement lazy loading for below-the-fold images."
