If you've managed to build trust with your audience (like, they subscribe to your newsletter and read it eagerly), you could sell them another fix for their problems (like a book, workshops or software)
so you don't count on google AdSense to monetize your blog?
My guess is that tech savvy audience will use Adblock mostly, hence Adsense revenue might be low for tech audience
I understand, Thx. But my experience is focusing on software technology and I'm new to blogging. I will try to learn what can be done to improve the revenue
