The best products that I found for sprucing up my garden are found at my local grocery store. They have an excellent stock of seeds to plant, seedlings, and a variety of different bushes and shrubbery.
From the documentation, Google parses your blog content and if it is pertinent, it will display a Gadget section on the right side tool bar beneath the Post Sections area. While my earning section indicate that this blog is Eligible for Affiliate Ads, none of my older posts on this Blog have this option available.
However, I have examined older posts in my 3 other blogs and have seen the widget available.
So, be on the lookout for a "Gadgets " section with an "Advertise products" choice when writing your posts. If it is there, then select an ad and include it in your article!
You can learn more about these Affiliate Ads by clicking on the link above, and reading the Blogger help article: Enable Affiliate ads in your blog posts .
PS: As an aside, I visited my post about 4 hours later, and the Advertise products Gadget was there! So, I selected a product and added it to this post!
