Editing Mobile-first indexing (section)

==Usage Types==
===Responsive Web Design===
Responsive web design is a technique that enables a website to automatically adjust to the screen size and orientation of the device it's viewed on. This method is widely recognized as one of the best ways to design a website for mobile-first indexing.
===Dynamic Serving===
Dynamic serving uses the same URL for both mobile and desktop versions but serves different HTML and CSS codes depending on the type of device that requests the page. While this approach requires more complex website design and maintenance, it's highly effective when implemented correctly.
===Separate URLs===
Also known as a mobile subdomain, this method keeps separate URLs for the mobile and desktop versions of the website. The different URLs then serve users depending on the device they are using.
