If the website is already running on the desktop, it requires a new display dimension for the mobile, and then responsive web design development may be more suitable as it provides a way to retrofit but in case the company requires a new site, one can design the mobile-first types. In adaptive, the developers create different layouts for different screen sizes where the relevant page is loaded for the suitable screen dimensions.
Such a design is device optimized and if the person visits the page using different devices it may look different. One of the drawbacks of the system is that the design may not be able to adapt to new screen sizes and multiple versions of the same pages are developed and modified each time a new feature is added to the site.

For this reason, it requires a lot of resources to maintain the multiple versions and this increases the work of developers. The page is delivered to the browser and then the changes appear as per the dimensions of the window. In many conditions approx. resolution is taken and if the screen size does not match, it can lead to the depiction of the layout, which appears imperfect and inconsistent.
It provides client-side updates, whereas, in the case of responsive web design the layout and scales are determined through techniques like CSS or media queries. Such pages may require certain resolutions where the size may take 30 percent of the whole page regardless of the screen and the other part of the page may fill automatically.
The designs on the adaptive server-side are modified before it is delivered to the browser. The pages may be optimized for each device and even in responsive web design, one may require multiple versions of the same to suit the individual requirements as there are infinite screen dimensions, and it requires a lot of work to manage. But one of the attractive features is that it can be easier to manage on responsive than on adaptive as the changes to content are made only in one place.
AWD can be useful in conditions when one requires regular updates as the changes can be easily integrated without affecting the entire content. It also supports strategy where the adaptive guidance helps to ensure consistency across page layouts and it also helps to ensure the flow of information is steady and Adaptive Web Design.

Design can be selected depending on the requirement of the client. If the page requires fast loading, AMP can be used which provides a lightweight version of the site where heavy content is eliminated.
This also helps in improving the SEO of the page as the page speed is improved due to the presence of a lighter version of HTML, JS, and CDN, and this improves desktop and mobile indexing. AMP pages were initially introduced by Google to compete with Facebook's instant articles, hence, it is supported by multiple platforms, search engines, and browsers.
