You can search on Quora or Reddit to see the types of questions people are asking, which will give you ideas for keywords and content.
Once you do write more content, do a review for accuracy. I took a quick look at the page for toasters made in the USA. The first toaster I looked at had a broken link. I found the correct link for that toaster and a second unit, and the Amazon description for both of them indicated they were not made in the USA.
