Is making web-related content (SEO, web design, etc.) worth it in the long run?

I'm interested in programming, and I want to make a website that talks about programming and have things like web design tutorials, etc. But I want to do more than give away free content on my website. I also need to make money from my website by putting ads like AdSense on it. So, is it worth it to make web-related content (SEO, web design, etc.) in the long run?
