Multiple h1 tags on a page are bad, I thought. And I would have left it at that except for something I didn’t want to do. I didn’t want to mess about isolating the h1 font that displays over a hero image just to get it to render at the size I wanted. And I didn’t want to change the h1 font size globally because it fits in neatly in the hierarchy of sizes h2, h3, etc. that I have on the site.
So I decided to look up something I took at immutable fact. That is, namely, that multiple h1 tags on a page are bad.
You can have as many h2, h3, etc tags on a page as you like as long as they are nested in order, but you should only have one big h1 to control the page. That is what I thought.
John Mueller from Google
I googled and I found a video on YouTube that John Mueller from Google did in December 2017. He was answering a question raised by someone who had more that one set of h1 tags or his page and wondered how Google viewed that.
Mueller said that provided the h1 tags made sense to highlights different parts of a page, then having them on a page are just fine.
All of which goes to show that it is worthwhile going back and revisiting facts one thinks one knows, to check whether they are still facts.
