AdSense isn't as popular among bloggers anymore because earnings have dropped and policies are stricter. Many now use alternatives like Media.net, Ezoic, AdThrive, Mediavine, or Adsterra. Others earn through affiliate marketing, sponsored posts, or selling digital products.
Affiliate marketing is also affected as they have reduced commissions.
Yes, many people have replaced Adsense with Ezoic. It's very common these days.
What better features and benefits they offer ?
AdSense has not really become unpopular imo but the way bloggers implement it surely has changed. As traffic and revenues from ad placements have become more unpredictable, bloggers prefer not to be dependent sollely on display ads.that is y a lot of bloggers implement affiliate marketing, sponsored posts, e-mail marketing or product sales into their blogs.
