My designer and I have been having an argument: we have a blog with short, 400 words posts. They have an H1 with nice keywords and a catchy title, and then a few subheadings. I don't like making the subheadings H2, because the font looks way too large in Wordpress, so my designer wants to make them all H4s, so the font looks to be a nicer size.
Here's my problem with that and why I usually just bold the subheadings: Is it really bad to put a bunch of H4s right under an H1, with not H2's or 3's to separate?
I'm reading different arguments on the internet about this and gladly welcome more debate and/or case studies. Thank you!
