Use as many subheadings on a page as it takes.

Okay, that’s not a great answer, but it’s pretty accurate. There is no set number. In writing hundreds of effective webpages, though, I would say two to three for most pages is ideal. But if the page is really long, you might have six or seven.

The general rule of the thumb that I use is this: You should have at least a paragraph or two under each subheading. Sometimes three paragraphs if they are short, but I try to break things up into bite-sized chunks. A webpage is just easier to read that way.
