If you own a blog that means you’re writing. Right? And that means that you can pitch your ideas to many platforms out there and get paid for your submissions. This website has all the ultimate lists for many niches, I subscribed there and get notified of so many platforms that I can hardly manage to write for them next to my steady work!
BONUS if you’re a writer and write short stories or poems, you can think about submitting your written work to some competitions. Google is your friend here since I could hardly list all of them here.
