  • Why site speed is so important?

    If your site takes too long to load, most people are gone. Not only that, Google’s best practice says your site should load in less than 3 seconds. If it takes more than 3 seconds, then your bounce rate will be high.That means that your site’s speed affects SEO, so if your site is slow, visitors will become impatient, and your site will lose ranking in search engines.
