How long does it take before my SEO improves and my website starts showing up in the results?

We'll be honest with you: There is no exact answer to this. However we have seen that with 2-3 updates a week, which are relevant and consistent with your business, our customers' websites start showing up in local searches on popular search engines like Google in 3-4 weeks. This is what is called organic web traffic.
Of course this requires you to create content. Think of it like fuel that'll make the car run. If you don't fill'er up, the car won't take you anywhere.
