First h1
This page has no meta description, a title well past the maximum, two h1 elements, an outline that skips from h2 to h4, images with no alt attribute and a canonical link pointing at a different page. Every check a report runs should have something to say.
Second h1
A second level
A fourth level, straight after the second
Two images above carry no alt attribute; the third carries an empty one, which is how a decorative image is properly marked.
