For small blogs, Ezoic is a strong first alternative due to its easier access requirements than Mediavine or AdThrive. It uses AI to test ad placements and can often increase earnings over basic AdSense. However, it requires a bit more traffic to join and can slow down your site if not configured carefully, so site speed optimization is key.
Mediavine is the premier choice once you hit about 50,000 monthly sessions. They offer much higher RPMs (revenue per thousand impressions), superior ad technology, and great support. The approval is stricter, but it's a clear revenue upgrade for growing blogs. It represents a tier of monetization that is a worthy goal to work towards.
For direct relationships with advertisers, consider affiliate marketing. Promoting relevant products on Amazon via the Associates program or through specialized networks like ShareASale or Awin can generate income that complements or exceeds ad revenue. It works well for niche blogs where you can naturally recommend products you trust to your audience, building a more sustainable income stream.
