Optimizing your images not only helps your WordPress site load faster, but can also boost your SEO.
When it comes to website’s speed, images are the most important factor behind website loading time. Google and other search engines give high preference to web pages that are highly optimized for speed.
As a larger number of people have started to use mobile and tablets to browse websites, users hate to wait for websites which take more time to load. Based on current technology trend, it’s better to enhance loading time of website before you lose your customers.
And hence, it has become a top priority to compress image on your website to speed up and rank your site higher in search engines. There are other excellent articles and plugins for enhancing your WordPress images experience too.
