Well, this one is pretty subjective, and it’s what we tried to get into in this post. Rank Math does offer more features than Yoast SEO, especially when you’re talking about the free versions.
However, that doesn’t necessarily mean it’s better for your site – it really just depends on whether or not you think you’ll actually use those features and how much you value going with the “more established” option in Yoast SEO.
