Extensions and plugins are additional tools that you can add to your online store to improve its functionality and capabilities.
For example, you can use plugins to add search functionality, integrate with social networks, optimize SEO, and more. Each plugin provides unique features and settings so that you can customize your store to your needs.
6. Responsive design
Responsive design is an approach to creating the layout and design of your store that automatically adapts to different devices and screen sizes.

With responsive design, you can create a store that looks and works well on smartphones, tablets, and desktops. This allows your visitors to have a pleasant user experience, no matter what device they are using.
To create a responsive design, you can use different technologies such as media queries, flexible grids, and others.
7. SSL certificate
An SSL certificate is a digital signature that ensures a secure connection between the server and your visitor's browser.
Installing an SSL certificate on your online store will help protect your customers' personal information, such as credit card details and shipping address. It also allows you to use the HTTPS protocol, which increases visitor trust and improves your search engine rankings.

Analytics and optimization are processes that help you understand how your visitors interact with your store and what can be improved to increase sales and customer satisfaction.
There are many analytics tools, such as Google Analytics, that provide information about traffic, conversions, visitor behavior, and more. You can use this data to identify popular products, identify weak points in your store, and conduct A/B tests for optimization.
Using these codes and tools, you can create a unique and attractive online store that will attract more visitors and help increase sales.
