How do images affect website performance and SEO?

Last Updated: Nov 8, 20261 min read

Images are often the heaviest part of a page. Oversized files slow loading, while well-optimised images improve speed and can also bring traffic from image search. They also help users understand products, places and results.

Use descriptive file names, alt text and proper dimensions, and load images lazily below the fold. Modern formats such as WebP or AVIF cut file size dramatically without visible loss.

Original images of your team, projects and products build trust better than generic stock photos.

Image best practices:

  • Format: use WebP or AVIF where possible
  • Size: resize to the displayed dimensions
  • Compression: reduce file weight without visible loss
  • Alt text: describe the image for accessibility and search
  • Lazy loading: delay offscreen images
  • Responsive images: serve different sizes by device

Our website development company in Dubai service includes image audits, and a SEO company in Dubai sets up automatic optimisation.

Pro Tip

At Awrange, we never upload camera originals directly. A 5 MB photo can slow an entire page.
