Using Images to Take Down Your Site Performance
Trying to slow site speed down? Learn how to use image requests and sizes to reduce your speed and ruin your customer experience.
In my last blog, I gave you five simple steps to slow down your site and ruin your customer experience. One of those steps involved images; specifically making them as big and rich as possible, using large mega-pixel images, and not compressing them. I also mentioned that truly creative people could find additional ways to use images to bring their site to a crawl.
While investigating some issues for an ecommerce website, I discovered just how creative some people can be. In their new ad campaign, the company dropped a 3.5 MB background image on their homepage—and in making sure they inflicted maximum pain on their customers, they requested that background image twice. That’s 7 MB of data to download for just two images. The chart below provides a clear visual of when this campaign was launched and their load speed was brought down with it.
I was able to stop the sea of red (and the alert spam) by blocking those images from loading with Catchpoint, but the site’s customers continued to suffer.
In addition to the background image(s), this company also included additional large images.
With the homepage originally a whopping 14 MB, it still weighed in at 7 MB without the images even being present.
This ecommerce campaign is a perfect example of how to use images to bring your site speed down to a crawl and your brand reputation to the gutter. If you want to learn how not to ruin your web performance, take a look at our recent blog post with expert advice on optimizing your objects.
