Yes, it is possible to make money through free blogging platforms, but it requires a lot of hard work and patience. Here are some ways to monetize a free blog:

• Affiliate Marketing – Promote relevant affiliate products and earn a commission when readers purchase through your links. Amazon Associates is a popular program for bloggers.
• Display Advertising – Sign up for ad networks like Google AdSense, Media.net, or Ezoic to place ads on your blog. You earn money when visitors click/view the ads.
• Sponsored Posts – Reach out to brands in your niche to sponsor posts and tutorials related to their products or services. Disclose these paid partnerships.
• Digital Products – Offer your own ebooks, online courses, templates, graphics packs, or other digital products for purchase.
• Consulting Services – Use your blog to highlight your expertise and promote paid consulting offerings to clients.
• Donations – Allow readers to send one-time donations or set up recurring monthly payments as a way to directly support your work.
• Merchandising – Sell t-shirts, mugs, and other merchandise featuring your blog’s brand and graphics.

It does require substantial effort to build traffic and an audience. And earnings may be modest. But by diversifying your revenue streams, you can make money blogging, even with free platforms.
