Do I need a subdomain for the mobile version of the site?

Question

Mobile development

There is a mobile version of the site and a desktop version. Is it possible to do without the "m" subdomain, so that a mobile version of the site with the same domain as the desktop version runs on mobile devices? And if so, what are the potential pitfalls?
I would be grateful for any tips and hints. Thank you.
PS Responsive design is not possible.

Answer 1

In my case, there were such reasons to make a separate mobile version (SPA):
a. The adaptive is very bold and takes a long time to load (in general, you need Bootstrap, etc., but you can, of course, file your own microbike)
b. A fully functional mobile version is not always needed and not always good (take any serious project, not some blog), and you have to load everything (in the mobile version, I don’t need almost all the libraries)
c. Potential SEO Issues
You'll have to maintain two codes, but if the mobile version is kept as simple as possible, this shouldn't be a problem.
There will be problems with the fork on which site to go to (I just solved this issue: https://toster.ru/q/226600)
If the site is simple enough, then adaptive is probably the best choice - it will always look good, links will always lead to the same place and there will be no crap on the server side.

Answer 2

Not needed, you should not separate the site into a mobile and desktop version, it is better to make an adaptive design.

Answer 3

Don't be foolish. In this case, you better make an adaptive site. But if you don’t like it, xs why, then determine the device type on the server and give it a separate output template!
PS You don't need to think that a responsive site can be very tight for a phone. After all, in fact, we get the same site as on the PC! Except for internet speed differences. There are many techniques to slow down the loading speed of a website. You just need to know how to use them!

Answer 4

needed. traffic is not everywhere rubber. well, of course, if your cms determines that the browser is mobile and gives it a mobile version. And if not?)

Answer 5

To be honest, I don’t understand what’s stopping you from taking an example, for example, from Wikipedia.

Mobile site
By the way, pay attention to m.habrahabr.ru itself.

Answer 6

Depends on the site. If it's convenient to make a version that would work both there and there, it's better that way. But if the design and content do not allow this, and the mobile version can only be truncated - definitely make the "m.site.ru" version. It shouldn't matter to the SEO.
