How Your Images Affect Your Site Speed and SEO (2024)

Let’s review how fast-loading images affect your site speed — and in turn, your placement in search engine results.

Sites that use too many images, or have images that are too large, have longer loading times. This can slow down your entire page, irritating visitors and actually hurting your site’s ranking in online search results. We may say that images are worth a thousand words, but if you don’t plan for fast loading times, they actually won’t be worth very much at all.

In this post, we’ll discuss why search engines like Google care about image load times, and how you can use Jetpack’s features to enhance your site speed by making those images load faster.

Why search engines care about your site speed

Here’s something you may not have known: increased image loading times affect your site’s rankings in online searches.

Google uses a set of more than 200 factors called algorithms (likePageRank, Google Penguin, Google Panda, and Google Hummingbird) to decide the order in which to display search results. The exact factors and their importance in calculating search engine rankings are not known, as Google does not reveal them to the public.

However, through experience and research, search engine optimization (or SEO) specialists agree that the most important factors include unique content, site structure… and page and image loading times.

A prolonged image loading time hurts reader engagement and creates negative user experiences. Over the last decade, our attention spans have dropped from an average of twelve seconds to eight seconds, according to Microsoft. If readers can’t see your fully-loaded pages in eight seconds or less, they may become impatient and navigate away from your site. When it comes to keeping readers interested, every second counts!

How WordPress manages your images and speeds up your site

A common practice that adversely affects your image loading time is using images that are wider than the content area within your theme. If your page is 1200 pixels wide and you upload an image that is 2400 pixels wide, your readers will have to load more data than they need to, unnecessarily increasing the image and page loading times.

Luckily, WordPress takes care of this behind the scenes by creating various sizes of your original uploaded image without affecting the quality. When you choose an image from your Media Gallery, you can pick a size that best fits within the content area — and loads less data.

By managing your image sizes, WordPress helps to reduce the load time of all of your images across all of your site’s pages.

Although it’s extremely important, size is not the only factor that dictates a good page load time. It’s equally important that your images are served quickly.
