Advertising is one of the ways to get traction, but for most brands it takes over 6 months (or a year) to build any income at all. It's a good way to promote local stores or coffee shops, and cheaper products, but the cost per click is high for online products and the initial investment is significant, and often acquiring a customer costs more than profit. For some brands getting a large number of initial users is essential to get the business profitable at a later point. Many startups invest in different forms of inbound or content marketing and build their steady traffic from freebies, tutorials and other relevant resources for their users, referral programs, freemium models and other tactics to bring users without investing in standard advertising. Advertising is a helpful addition when you implement retargeting pixels and promote to the right channels.

The steps are the easy part. It's the execution. You can put together a great lead gen machine using content, cookies, and email marketing.

We have an overlapping but non-competing interest in this area. What I'd recommend is ... skip the books or guides on Google AdWords or the Bing equivalent. You've already read enough, and your question is framed with enough specific detail that you're obviously no slouch and probably past the beginner stage, I'd say. Reading guides would provide steadily diminishing returns. DIY time! Brainstorm keyword ideas. Research the search stats. Once you feel you've covered all the relevant search queries and prioritized them, then it's time to run experiments. That's why I say skip the books. At a certain stage, you have to leave biology textbooks behind and go dissect some frogs or observe the live frogs (your customers?) in nature. Nothing is more empirical than running an efficient SEM campaign. You know this. Rules are starting points to b left behind in this space. Books and guides might provide some preliminary tips (at best) or be authoritarian (at worst). Just arrange your spending alternatives as hypotheses. Measure which strategy performs better using some carefully planned A/B testing over a statistically significant period of time / impressions / clicks. Set aside the generalizations. No author will give you what you need because you're already thinking of your problem at a granular level of detail. Brainstorm. Plan tests. Measure. Rinse & repeat. If you want to put 2 heads together, I might be able to throw out some extra ideas. But you don't necessarily need another person.
