Content optimisation
Single H1
No more than one H1 element
What we check
No more than one H1 element
Why it matters
Several H1s split the topic, so no single subject stands out.
How to fix it
Keep one H1 and demote the others to H2.
How it affects your score
This check sits in Content optimisation, which is worth 30% of the overall score. A critical result costs the full weight of the check; a warning costs half. If we can't measure it on your page, we leave it out of the score entirely.
