You have a great website (may be a regular corporate site or an ecommerce site) but it is non-responsive. When user views it on mobile devices it distorts or requires scrolling.
You are concerned what to do?
1. Redesign the Complete Site in Responsive:
It’s a tough call but a real solution. If your site is an ecommerce store created on platforms like Magento, Opencart , Woocommerce etc. you will need to have your development team to restart the entire process by selecting a new responsive design template based on the latest version.
