Why is my website slow?

A slow website costs you both rankings and customers - people leave before it loads. The good news: most slowness comes from a few common causes, and you do not need a perfect score to fix the ones that matter. Here is what actually slows sites down.

Why speed matters

Speed affects two things: rankings (Google uses Core Web Vitals as a signal) and conversions (every extra second of load time loses visitors). You do not need to be the fastest site on the internet - you need to be fast enough that people and Google are not penalizing you.

The usual culprits

• Oversized images - by far the most common cause. Huge photos shrunk in the browser still download at full size.
• Too many scripts - tracking tags, chat widgets, and plugins that all load up front.
• Slow or cheap hosting - the server itself takes too long to respond.
• No caching - the site rebuilds everything for every visitor.

Which fixes actually matter

Start with images - compress them and serve them at the right size, and you will often fix most of the problem in one step. Then remove scripts you do not use, enable caching, and consider better hosting if your server response is slow. Do not obsess over a perfect 100; chasing the last few points rarely changes anything a visitor notices.

What is in your control versus your platform

Some speed factors are yours (image sizes, extra scripts); others are baked into your website builder or host. An honest audit tells you which is which, so you do not waste time trying to fix something only your platform can change.

How to check your speed

Run your site through the website grader for real Google PageSpeed data with plain-English context - what each number means and what is actually worth fixing. It separates the issues you can act on from the ones you cannot.
