Server-side GTM implementations on Stape or self-hosted Cloud Run. We move conversion signal to first-party infrastructure so your Google Ads, Meta CAPI, and downstream analytics keep working as browsers keep tightening the screws.

Platform match rates that actually move your automated bidding
A tracking stack you own, not rent from a third party
Client-side is enough until it isn't. Safari's ITP, Firefox's ETP, ad blockers, and iOS privacy features collectively drop 20-40% of browser-side events depending on your audience. If you're running paid media with smart bidding, that's a 20-40% signal degradation going straight into Meta and Google's algorithms. Server-side fixes it.
Stape for 90% of accounts — it's faster to ship, handles scaling automatically, and includes monitoring. Self-hosted on Google Cloud Run makes sense if you need custom server-side logic, have strict data residency requirements, or spend enough that Stape's enterprise tier costs more than running your own infrastructure.
Usually yes, sometimes significantly. Better signal quality means smart bidding algorithms converge faster and optimize more accurately. Typical gains are 10-25% on Meta match rate and 5-15% on Google Ads conversion volume, which flows to better bidding decisions. That said, it's not magic — a broken campaign structure won't be saved by cleaner tracking.
Two to four weeks for most accounts. Week 1: architecture, container setup, initial event mapping. Week 2: Google Ads and Meta CAPI forwarding with deduplication. Week 3: QA, consent alignment, monitoring. Week 4: go-live and post-launch tuning. Complex multi-domain setups or custom CRM integrations can push to six weeks.
Included. CAPI via server-side GTM is the cleanest implementation path — one server container forwards events to Meta (via CAPI), Google (via Ads API), and GA4. No bolt-on CAPI Gateway, no duplicate event logic, single source of truth for conversion signal.
Consent signals flow from the client to the server container along with each event. The server then applies the correct forwarding rules: full event for consented users, anonymized or blocked for declined consent. We validate this end-to-end with real browser sessions during QA, not just by trusting the config.
