_Can_ you? Sure, but it's probably not the most effective way. What you're describing is "content marketing," and it's usually very good at improving the middle and bottom of the funnel. Meaning, when someone already knows about your site, your content marketing can help convert them to a trialer, or customer.

If you care about increasing conversions, absolutely do content marketing.

If you care more just about raw traffic numbers, you'd be better off doing something like search engine marketing (SEM), PR, and general marketing. Each of those drive the top of the funnel, and not much else.
