I am dealing with this right now.<p>For me, this "post HN" or "pitch Techcrunch" simply doesn't work. To receive HN upvotes you have to Show HN a product very specific to tech hackers crowd - my product is a product social network, I am sure no bootstrapped private social network would receive any attention here. Show HN small, neat, open source projects go much better than "try my product" Show posts. And for TC you would have to be much more high-profile than me. Like eing one backed by a famous accelerator, funded or a former early employee of Google/FB/Twitter.<p>What I am doing is dealing, progressively with three bottlenecks: visitors coming, visitors signing up and users coming back.<p>For the first one, Adwords is good enough. I spent $5 daily, receive about 300 clicks (1 or 2 cents CPC). This give me a constant flow of visitors to run the relevant experiments.<p>For the second one, I am improving right now. I have about 4% of the visitors signing up. I am changing my landing page and will do some tests to bring it, at least, 10%. Don't be tempted to focus too much on improving sign up rate right now. The only purpous of these 2 steps is to give you a good enough flow of new users so you can test your retention (or revenue per user) rate. Nothing more. The same advice for your Adwords campaign, create a good enough one, so some visitors go to your website, don't try to be a master of Adwords (for now).<p>And third, the goal of all your steps so far, retention (or generating revenue, I don't know your model). For me, having 30+ new users each day is enough for me testing my retentions with different tactics. If you need more than this, than you might raise your Adwords daily budget, or try a little more to improve your sign up rate. But fix your number of new users I just work hard enough to match this number.<p>When you have a good enough number of daily new users, than your work on marketing match with your goal to deliver value to your customers, and then good enough is no more enough. This is when you must excel on testing, iterating and improving your product. With no excuses as "only if people knew what I am doing"....<p>Good luck!
