To break into organic traffic, try writing articles that answer questions your customers or visitors are likely to search for.
For example, if you have a business installing soundproofing materials, write blog posts about how to soundproof a room, or how to install a soundproof door.
To get inspiration for the kinds of questions people type into Google use a website called Answer the Public. Because I'm new here, I'm not allowed to include a link, but just Google 'Answer the Public'. When you get to the site, type in words describing your business, for example 'soundproofing' or 'soundproof', and it will supply you with loads of questions that people ask.
Be warned, blog posting is not a quick route to traffic, especially if yours is a new website and you are targeting a competitive industry. However, if you are comprehensive and helpful it is a reliable long-term strategy for free organic traffic.
Good luck!
