When it comes to boosting website performance, most businesses focus on keywords, backlinks, and content quality. But there’s one silent powerhouse many overlook: image optimization. In today’s digital-first world, where users expect lightning-fast websites and visually appealing content, how you handle your images can make or break your online success.
Think about it—images often account for more than 50% of a page’s total weight. Without proper optimization, they can slow your site to a crawl, frustrate visitors, and even cost you precious search engine rankings. On the flip side, well-optimized images can supercharge your site’s speed, improve user experience, and even boost your SEO results significantly.
In this blog by Denver SEO, we’ll dig deep into why optimizing images isn’t just a “nice to have”—it’s absolutely essential if you want to stay competitive online. We’ll show you real-world benefits and strategies for making sure your visuals work for you, not against you.

When you optimize an image for the web, you’re not just thinking about how it looks—you’re thinking about performance, accessibility, and SEO.
