We use a fat layer navigation which partly consists of content that some CMS users insert with a rich text editor (TYPO3 is the CMS btw).
By this we have several
<hX> tags inside the
<nav> tag which contains the navigational layer.
Now a SEO agency tells us that this is bad.
I searched the internet and the few answer I got are contradictory.
Are there any facts that say bad or not?
