Page load speed
Both Google and Bing take page-loading speed into account in their website ranking algorithm.
Users may leave your site if they have to wait even just an extra few seconds for each page to load. That would hurt your dwell time, increase your bounce rate and reduce the number of pages viewed – all of which could hurt your SEO ranking.
There are many ways to increase page load speed, some of which include using a caching plug-ins, making sure the code is clean and streamlined, optimizing image sizes, reducing the number of plug-ins, and minimizing redirects.
