Did you know that slow websites lose visitors? Studies show that 53% of people leave a page if it takes more than 3 seconds to load.
One of the biggest reasons for slow websites is large image files. In this article, I'll explain why image compression is so important for both SEO and page speed.
Key Takeaways
- Google uses page speed as a ranking factor
- Images make up 50% of most webpage sizes
- Compressed images = faster loading = better rankings
- Faster websites have lower bounce rates
What is Page Speed?
Page speed is how fast your website loads. When someone clicks on your website link, they want to see the content quickly. If your site takes too long, they will leave and go somewhere else.
Google measures page speed in different ways. The most important ones are called Core Web Vitals. These include how fast the first content appears, how quickly the page becomes interactive, and how stable the page is while loading.
Images are often the heaviest elements on a webpage. A single uncompressed photo can be 5MB or more. That's bigger than the entire code of most websites! This is why compressing images is so important.
Fun Fact: Amazon found that every 100ms of delay in page load time cost them 1% in sales. For a company that big, that's millions of dollars!
How Page Speed Affects SEO
SEO stands for Search Engine Optimization. It's how you make your website appear higher in Google search results. And guess what? Google cares a lot about page speed.
In 2021, Google made page speed an official ranking factor. This means faster websites have a better chance of ranking higher than slow ones. Here's why this matters:
Higher Rankings
Fast websites rank better on Google. More visibility means more traffic to your site.
Lower Bounce Rate
When pages load fast, visitors stay longer. This tells Google your site is valuable.
Better User Experience
Happy visitors are more likely to share your content and come back again.
More Conversions
Fast websites convert better. Whether it's sales, signups, or downloads.
Why Images Slow Down Websites
Let me give you a simple example. Imagine you're sending a letter. A small postcard arrives quickly. But a heavy package takes longer to deliver. Websites work the same way.
When someone visits your website, their browser has to download all the files. Images are usually the biggest files. The bigger the images, the longer it takes to load.
Here's what typically happens with uncompressed images:
A 5MB photo takes 4+ seconds to load on a fast connection
On mobile data, it can take 10+ seconds or fail completely
Multiple large images can make your page unusable
A 200KB compressed image loads in under 1 second
Works great on mobile even with slow connections
Looks exactly the same to visitors
