A slow-loading website can annoy your visitors and drive them away. With more than 30% of websites being accessed from mobile devices, you can safely assume that not all your website visitors will be using a high-speed Internet connection. As a result, a lightweight website that loads quickly and allows visitors to begin interacting with it as soon as possible is best.
It is not always possible to reduce the overall size of the web page without getting rid of vital elements. However, images on the web page can always be optimized through compression to improve website performance. As more and more websites are designed to impress at first glance, they contain a lot of high-resolution images. These images can very quickly make the web pages bulky and decrease loading speed. Optimizing these images will provide your website performance with a quick boost.
Image optimizing plugins are great for compressing images into a smaller file size. They help you decrease overall web page size and enable faster page loading. Page loading speed is also a vital factor in Search Engine Optimization, hence a good image optimization plugin will help not only boost your page SEO, but your overall website SEO.
