Considering your actual approach to the server-to-server tracking is one of the biggest decisions to make. Google’s recent Server-Side container option for Tag Manager has placed server-to-server capabilities in the hands of many more brands who perhaps didn’t have the knowledge or resources to complete a server-side implementation traditionally.
This is a great opportunity to also review all of your marketing tags. Moving other trackers such as Facebook to a server-side container in GTM will go a long way in speeding your site up for users. We know how important page load speeds are for SEO, and this is a brilliant way of improving your Core Web Vitals scores.
