Of course, offering products and services doesn’t have to be mutually exclusive from using ads. You can do both, but what I see happen is that when you start to make $5 from ads you try to figure out how you can make even more and that becomes your focus. The tactics you use to boost your ad revenues are often the ones that prevent you from building your list and promoting your own products.
Include keywords in important places. Include them in your blog post title, the large "headers" introducing a new section, the first few sentences of your post, and in links.

You don't have to try to monetize your joy.

Make it easy for readers to browse – If you want more pageviews, you should make it as easy as possible for readers to read your other blog posts. You will want to make it easy for readers to find your blog homepage, categories, tags, search bar, and so on. Also, I recommend including links in every single one of your blog posts, so readers can easily find related topics.
