Image Sprites – Combine Multiple Images into a Single Image

It comes from the need to load different aspects of a single image at different times to boost site performance. It dates back to 1975 when it was faster to display a part of a single image than to load new images continually. The idea was to load an image once, rotate it, and display different parts of it, based on the requirement. Some popular software such as SpriteMe, SpriteCow, and Spritepad are used for generating Sprites.

Image Size – Go for Light-weight Images

As said earlier, the size of the images affects the speed of your website. As such, aim at using light images while preserving visual quality. It is recommended to never resize images using HTML or CSS. Use an image of the required width and height as much as possible. For example, if you need a 200px by 200px image, don’t use an image that’s 500px by 500px. It is also recommended to use images of high-quality and local caching features wherever possible.

SEO for Images – Naming Your Images Right

It is possible to drive more traffic to your website using image SEO. You can do this by naming your images appropriately. For instance, instead of “image001.png,” use “choosing-best-image-file-type.png,” and so on. On top of that, add alt texts to all of your images after uploading. With the help of these alt texts, search engines can now “see” and index your web page in the image search section accordingly. 

Keep Improving with the Help of Google Analytics

It all comes down to giving the best experience to your visitors as much as possible. For this, you need to know your visitors and the devices they use to access your site. That way, you can choose the ideal image formats and sizes. For instance, if most of your visitors use the Chrome Browser, you must provide additional features to support the use of WebP image files in WordPress.

In summary, choosing the ideal image file type for your WordPress site is vital as it helps you get the right balance between factors such as speed, UX, performance, SEO, Search Ranking and consistency.
