Ask Should I avoid keywords where Amazon organic listings dominate?

[Brajet]

Sometimes when searching keywords, most of the first page is filled with Amazon product pages, and that made me wonder if it is still worth targeting those keywords. It can be hard to compete because Amazon is a very strong site, but sometimes blogs still rank if the content is very helpful and detailed. I think the decision depends on whether there are blogs on the first page, not just big stores. That can show there is still a chance to rank. How do others decide when to skip such keywords?
