I ran ClickUp's homepage through an audit tool and spotted something easy to miss: three H1 tags live in the DOM at the same time.
Most likely a side effect of layered A/B testing - multiple hero variants render in the markup at once, even when hidden via CSS. Visually fine, but search engines and AI crawlers read all three.
Three competing H1s means no clear signal to search engines about what the page is actually about — each one dilutes the others.
Worth checking on your own site if you run A/B tests on hero sections. How often do you audit your header structure - H1s, hierarchy, duplicates?
