I've been testing different ways to monetize my blog and what has worked for me better than anything else has been building a subscriber list through my auto-responder service. I give away ebooks and reports to get people to subscribe. Many of my subscribers are just freebie seekers, but some of them will purchase a product that I may promote once per week. I'm not getting rich, but the larger my list grows, the more sells I make when I send out an email offer. My last offer was my own report that I wrote on getting more subscribers and views on YouTube. I made 4 sales at $7.00 each. Like I said, I'm not getting rich, but it is growing. I hope this idea helps.
