Establishing a clear goal is essential to developing any successful website, including those that are designed to be mobile friendly and work on different types of devices.

Depending on what you need out of your site, there are various platforms available for creating responsive websites such as WordPress or Bootstrap.

Create visual representations in order to ensure that all components fit properly across all device sizes during development process; this will help determine how design elements should adapt when viewed from different screen resolutions so it looks good no matter where it’s viewed from

Make sure everything works correctly regardless which device/platform users access the content with by testing regularly throughout entire development cycle – use tools like BrowserStack or CrossBrowserTesting – these allow developers preview changes quickly without having too much overhead time dedicated just towards testing itself!

Use HTML5 semantic markup language along with CSS3 media queries when building pages – This enables designers create layouts tailored specifically around certain resolution ranges (e g tablets vs smartphones). Additionally, consider using JavaScript frameworks like jQuery Mobile if more interactive features needed within page designs themselves (such as custom animations etc)

As part of ensuring fast loading times across multiple devices make sure optimize version each resource used accordingly! For example– take advantage ‘srcset’ attribute over standard <img> tags , combine small files into one larger file instead several smaller ones whenever possible..etc

To check whether performance goals have been met after deploying final product run tests against real world data sets ! Tools such GT Metrix provide insight into major issues existent webpages can cause due bad code structure / slow loading graphics etc…this way teams identify areas improvement prior going live publicly online

Once the responsive website has been developed and deployed, it is important to monitor its performance over time. This can be done by regularly running analytics tools such as Google Analytics on the site in order to track user engagement, page visits and other metrics that indicate how successful the site is being. It may also be beneficial to conduct A/B testing of different page designs or features in order keep improving upon what has already been created and optimize for various device types/screen sizes. Additionally, engaging with users via social media channels such as Twitter or Facebook will help establish a more direct connection between you (the developer) and your visitors – this could lead finding out even more about their needs based off feedback provided through interactions there!
