General

It should be possible to wrap conditions around your meta tags so certain meta tags show up on certain pages only:

{% if collection %}
  {% if collection.handle == "testcollection" %}
    <meta name="description" content="This is my testcollection">
  {% endif %}
  ....

{% endif %}

or

{% if collection %}
  <meta name="keywords" content="{% for tag in collection.tags %}{{ tag }} {% endfor %}">
{% endif %}

So.. for example, if it was on a product page and you wanted to have the meta description tag read:

My store presents product name blah blah blah. (Where product name is dynamic.) What would the collection.handle be? What would the product name variable be?

{% if collection %}
  <meta name="keywords" content="{% for tag in collection.tags %}{{ tag }} {% endfor %}">
{% endif %}

Daniel, i understand where you put your keywords in ur code. But where do you put your collection handle in the code above?

Is it here?

for tag in COLLECTION-HANDLE.tags

Thank you

Where exactly to you insert it in theme.liquid?

Cheers
