Hey @smileyrox
Welcome back! What I’ve found works most reliably is when you create an embedded signup form, then place that on distinct page of your Shopify store.
The page could be mostly blank, with the only content being the embedded signup form. If you want to give people a better place to start, you could embed the signup form at the top of the page, then below that place a bestselling product section, or a gallery of customer reviews/ UGC depending on what you have available to work with.
I took a quick look at that help doc, and attempted to view the example form with the Klaviyo demo site that was linked to there, and the form didn’t display for me. All I got was the site’s homepage.
So overall, using your own page built for the purpose of hosting that embedded form will give you more display consistency, and more precise targeting. That way, you can have the URL slug contain “instagram signup” and then link to that URL directly from your IG bio and stories as needed.
Warmly,
Gabrielle
