Duplicate H1 for collection titles

[Ljvapes]

Hi all I have run my netpeak spider app and i have a red error "Duplicate H1" and there are over 1000 in there. 

I have the below code in the (collection-header.liquid) 

<h1>{{ collection.title | split: '|' | first }}</h1>

Is this correct as it looks like the collection titles and everything in them is set to H1 and this maybe causing Duplicate H1 tags?

The issue you're encountering is due to the use of <h1> tags for your collection titles in collection-header.liquid. If every collection page, or even individual collection items, has the same <h1> structure, it could lead to duplicate <h1> tags being flagged by SEO tools like Netpeak Spider.  

• For collection pages: <h1> is appropriate for the main collection title (e.g., the title of the entire category).
• For product titles or collection items: These should not use <h1> but could use <h2> or <h3> instead.  
  
  

exmaple 
 {% if forloop.first %}
<h1>{{ collection.title }}</h1>
{% else %}
<h2>{{ collection.title }}</h2>
{% endif %}​
