How can I monetize my Website?

During this summer I made a website about plants. I only received 2 or 3 visits a day and I abandoned it.

Today I visit google analytics and I see that I receive about 60 visits every day.

I will continue working on it to see where it arrives. What do you recommend that is not adsense and amazon affiliates?

It depends on the kind of ads you're looking for. If you want something aggressive (which I don't suggest) you can try popups/popunders, otherwise you should stick with Adsense. In your case affiliates may be the best way of monetizing your website, Amazon is not the only website that provides this.

I recommend Adsense + Amazon combined with tutorials/how to's for planting different things (so they need the stuff from amazon ).
Next to that I would create a shop and sell products/seeds next to it.

Maybe Ebay or Amazon affiliates. You could do a dropshipping Shopify store with plant products as well. You will probably need to get your traffic up to about 20k a month before implementing Adsense. Good luck!
