URL structure suggestion for new category

[ayberk]

I have a history-culture page that gets about 100000 visits a month. I want to create a how-to section with mobile content (step by step guide) on this site. Should I create it as domain.com/tech or tech.domain.com? The current url structure is domain.com/postname.

Thank you.

You don't mention whether this is a static html website or on a platform such as WordPress or something else, but that can make a difference when it involves site structure, you want to set up a structure that can grow or shrink as time goes on.

When you mention "a how-to section with mobile content" does that mean that the site is not currently mobile friendly?

Sorry I have no suggestions yet, but clarifying the situation could make a difference in getting useful responses.
