My blog is getting 50 unique visitors per day

There is still quite a bit to consider here. The type of traffic you're getting matters. You can use Google Adsense, if you want, but I am not an advocate for advertising programs.

I prefer affiliate products and your own product. If you don't have the ability or time to make your own product, find a few good affiliate products to weave into your content.

Of course, the products need to fit into your niche, too.

Another good choice is the Amazon Associates program. You can use it to promote anything sold on Amazon, which can be very helpful.

Although you are correct. But I will not suggest affiliate products because even its a very rare niche 50 unique visitors per day is much less. The site must have 100-500 visits per day.
