 Blogging allows you to share your expertise, passion or even daily musings with the world and guess what? You could opt for advertising where companies pay to have their ads displayed on your blog. Affiliate marketing is another lucrative option. You promote a product or service and earn a commission on any sales made through your referral link. And let's not forget sponsored posts where brands pay you to write about their products or services. The key to successful blogging is authenticity, consistency and providing value to your readers.
