The practice of developing and providing high-quality photographs in the optimal format, size, and resolution to maximize user engagement is known as image optimization. It also entails identifying pictures correctly so that search engine crawlers can read them and comprehend the context of the page.

According to HTTP Archive, as of November 2018, pictures make up on average 21% of the entire weight of a web page. Because photos take up more space on a website than any other component, their size and complexity significantly impact site performance.

When you minimize the size of photos without sacrificing quality, page load speeds increase, and visitors' experiences improve as well. According to an Aberdeen Group research, a one-second delay in load time results in a 7% loss in conversions, and roughly 40% of users quit a website that takes more than three seconds to load.

Improved user experience and interactions with your site enhance search engine results, resulting in increased customer engagement, conversions, and retention. Furthermore, because optimized photos take up less server storage space, site backups will be performed faster.

How can you optimize your images?

Resize the images - The size of an image and the size of a file are not the same thing. The dimensions of a picture are referred to as image size (e.g., 1024 by 680 pixels). The file size refers to the amount of storage space required on the server (e.g., 350 kilobytes). Images with a better resolution and larger size (typically taken with a professional camera) take longer to load. While they perform well for print reproduction, they must be scaled down to fit on the web without sacrificing too much quality.

Choosing the appropriate file format is important.  PNG, JPEG, and GIF are all widely used image formats. Each has its own set of advantages. For photographs with a lot of colors, I prefer JPEG, and for plain photos, PNG.

When a picture is compressed too extensively, the file size is reduced but the image quality suffers. On the other hand, when you pick a low compression rate, the image quality is excellent, but the file size is enormous. To find out what works best for each image, you should experiment with different file formats and compression rates. Many image-editing programs, including Adobe Photoshop, feature a “save for the web” option that reduces file size while maintaining picture quality.

The use of alt tags - Although viewers may comprehend what an image is about, search engine spiders want further information. It's hard for search engines to correctly index your visual content without alternate text. A decent alt tag not only gives context but also aids visually challenged people. Search engines may interpret the alternative text to help rank a website even if pictures aren't loaded due to a malfunction. To increase exposure, insert brand-relevant terms here. Just stay away from keyword stuffing.

Optimizing the title of the image - If you're using WordPress, the picture title is normally derived from the file name, so you may leave it alone. If you don't use WordPress or the title doesn't adequately describe the image, rename it using the keywords in the same manner you would file names. Image names aren't as significant for SEO as alt text, but they can give more context. In terms of user engagement, image titles are more useful. Consider using a short call to action like "purchase now" or "download now."

Insert captions - If you're using WordPress, the picture title is normally derived from the file name, so you may leave it alone.
