Owlcure Analytics tracks pageviews by themselves. If you are using Google Ads Api correctly through window.dataLayer, Owlcure Analytics will use this layer, and you don't need to set up anything more.
Pagetype product should be used on the product detail page. It is necessary to add the parameter owl_product_id, which is product identification used in the product XML feed.
Pagetype home should be used on the homepage page. It doesn't need any other parameter.
Pagetype cart should be used on the cart detail page. If you want to use some personalized block on this page, it is good to provide the parameter owl_cart. This parameter contains an array of product ids, which are currently in the customer's cart. Product ids have to be the same as product identification used in the product XML feed.
