Image Optimization
The image on the left is roughly 10% the size of the image on the right and loads much faster. Can you tell the difference in quality?
Image optimization is about shrinking the size of the image on disk without disrupting the quality in a noticeable way. It may not be a big deal for a page with only 1 or 2 full sized images, but the more images you serve, the more of an effect this has on your loading times.
As you likely know, the faster your pages load, the more likely folks are to stick around. The more folks stick around, the more they buy!
