Welcome to the Q&A Forum

Hi everyone! Only a year late to this question... Do you know if anyone has done any A/B testing on how H2s in the nav can negatively affect a website's rankings? I'm on the same page with everyone that it is a big no-no to do, but am getting push back from our development team. They want me to prove that it hurts a website before they change the site. Figured I'd reach out here to see if you any of you have seen tests that prove this. Thanks you! -Rachel
