Starting a blog can be an excellent way to make money online, but not all blog niches are created equal—some attract much higher advertising revenue than others. This article is designed to give you 100 blog niche ideas to help you find a topic that suits your interests while also maximizing your earning potential.

One of the biggest factors that determine how much money you can make from a blog is CPM (Cost Per Mille)—a term that refers to how much advertisers are willing to pay per 1,000 impressions (or views) of their ads. Niches related to finance, business, and technology tend to have higher CPMs because they attract audiences that are ready to spend money on high-ticket products or services. On the other hand, hobbies and entertainment typically have lower CPMs because they appeal to a broader audience with lower purchase intent.

If you’re planning to start a blog, choosing the right niche can make a big difference in how much money you earn from display ads, affiliate marketing, and sponsored content. Below, we’ve categorized 100 blog niche ideas based on advertiser demand—ranging from high-paying industries to more general interest topics. Whether you’re looking for a lucrative side hustle or just a fun creative outlet, you’ll find plenty of inspiration here!
