The landing speed of websites is one of the lead factors for user experience. Slow opening websites may cause users to get bored and close the website. This situation redounds negatively on both your organic results and your advertising works.
To increase the speed of your web site's landing, you should conduct speed tests regularly and make necessary updates by following instructions.
PageSpeed Insights is a good alternative for speed tests.
To analyze your website on all devices, add your website's URL and click the ''Analyze'' button. By evaluating desktop and mobile results, define the updates that your website needs. New improvements will increase the landing speed of your website and provide a better user experience.
