Hey @Mark_Huggett - Kevin here... Shopify SEO + Google Analytics consultant based in California. I can help transition all your Google Ads and Google Analytics tracking into Google Tag Manager. I work with several web agencies as their go-to GTM guy and Shopify is my area of expertise. Email me (email@example.com) your store's URL and let me know whether you already have GTM implemented and I'll let you know if it's a good fit. Thanks Mark!
