I agree w/ @wesleysmits, but there's another interesting idea. So:
- Post every 2 weeks (as suggested by @wesleysmits)
- Subscribe to something like hittail.com ($10/mo), and write blog articles for a all the long tail keywords it suggests (YMMV). The way it works is HitTail will find a bunch of long-tail keywords e.g. "How do I replace my Samsung Galaxy battery?" users used to find your site. It'll suggest some blog titles that you write, and you just crank those out. These articles will tend to hit good ranks on these specific keywords, and bring in trickles. Build enough trickles into your site, you get a stream.
