Website loading speed is increasingly important for SEO. Google analyzes your website speed and if its not up to par with competitors, you may just be shunned.
It’s important to regularly analyze your page load speed and optimize its loading time. There are several simple ways to optimize loading that many website managers ignore. Reducing image sizes throughout your website is one of the best ways to help your site load faster. I’ve seen clients with enormous 5000×5000 pixel images on their site that make pages load at snails-pace.
