Image optimization for the web & How to?
Why is it important to optimize images for your website?
They say a picture is worth a thousand words, which is one of the reasons images are so important e.g. in ecommerce. Without the customer being able to pick up, touch and inspect product, they rely heavily on the images to understand the color, the quality, and the story of the product.
So it goes without saying that your images need to be hi-resolution and crisp. But, this comes at a price. Large, high definition images can have huge file sizes. Put a few of these on your site and the customer experience of navigating can end up in long wait.
Not only will this cause visitors to bounce, but in time, Google will notice as well, and this can affect your SEO.
