The short answer is yes, you can use affiliate marketing for bloggers in any niche that you are in. The question is the niche that you are in, does it have affiliate marketing products to promote and can you promote them? There are so many affiliate marketing Programs to join that you can be in any niche and promote products. Places like https://www.walmart.com/ and https://www.amazon.com/ both have affiliate programs that you can join and they both have pretty much every niche that you can get into. Now there are some niches that I don’t think you can be an affiliate For like selling high price items and things like guns or fireworks.
There are some things that you can sell online but for the most part, you can sign up with https://www.homedepot.com/ and other companies to promote different products. I think it may be hard to sell a high price sofa without the person sitting on the sofa or looking at it but there may someone to buy that. The key here is to not have your niche too small or box yourself in to one thing. If you are blogging about washer and dryer reviews, I would a blog about the whole laundry room so that you can talk about different things you can have in your laundry room or different cool tools to make washing clothes easier.
Can affiliate marketing be used for bloggers in any niche?
Lets face it, how many washer and dryers can you do a review on? But there are other things that you can write about and you can show people how to save money while washing clothes or how to wash clothes faster with your tips. You could build a eBook showing people how to save money on washing clothes. This is how you can turn this into a business but don’t box yourself into one niche. If you are blogging about gardening, you can blog about how to keep bugs out of your house, how to save money on gardening tools, how to find cheap outside sofa for your deck and other things that relates to gardening and outside. Yes affiliate marketing can be used for bloggers in any niche.
