If your website doesn’t automatically adjust to various screen sizes, you’re probably loosing visitors. The percentage of website visits by smartphones and tablets is rapidly overtaking traffic from laptops and desktops.
You may need to test your site for responsiveness, particularly if it’s an older website. Simply visit your domain using a laptop, a tablet, and 1 or 2 smartphones (they vary in size). Sometimes, a small bit of code can do the trick…and sometimes a major re-write is needed.
