sGTM/Google Tag Gateway Services

Cleaner data starts here.

Capture cleaner, more reliable data with a tagging approach built for today’s privacy‑restricted, ad‑blocked web.

At Marcel Digital, we help B2B organizations rebuild trust in their measurement by implementing modern tracking architectures, Google Tag Gateway and server-side Google Tag Manager (sGTM). These solutions reduce data loss, strengthen measurement accuracy, and unlock resilient tracking across marketing platforms.

Why You Need Modern Tagging (And Why It Matters Now)

Today, 30–50% of your web traffic is underreported due to ad blockers, browser restrictions, and deprecated third‑party cookies. This means:

Conversions appear lower than they actually are
Audiences shrink
Optimization algorithms perform worse
Cross‑channel attribution becomes unreliable

Before choosing a tagging solution, get a sense of your own data loss. You can estimate this by completing our Analytics Maturity Assessment.

Modernizing your tracking is essential for maintaining performance, targeting accuracy, and reliable measurement.

What Is Google Tag Gateway?

Google Tag Gateway routes the Google tag (GA4, Google Ads, CM360) through your own first‑party domain instead of Google-owned URLs. Because tags load from your domain, they’re far less likely to be blocked.

Benefits of Google Tag Gateway:

Fastest, simplest path to improved tracking
Requires minimal setup; sometimes only a few clicks with a CDN like Cloudflare
Improves reported traffic, conversions, and behavior data (Google reports ~11% uplift)
No major infrastructure changes

Limitations:

Only works with Google products (GA4, Google Ads, CM360)
Does not support Meta (Facebook) CAPI, LinkedIn, Bing, CRMs, heatmapping tools, or external ad platforms

What Is Server‑Side Google Tag Manager (sGTM)?

sGTM moves your tag execution to a secure server environment you control. Instead of the browser firing all pixels, sGTM collects data server‑side and routes it reliably to 3rd‑party platforms.

Why companies choose sGTM:

Works with all major ad platforms (Meta, LinkedIn, Bing, TikTok, etc.)
Required for Meta’s Conversion API (CAPI)
Supports heatmapping tools, CRMs, call tracking platforms, and custom endpoints
Reduces page bloat and improves site speed
Offers a lot of flexibility: data transformation, validation, enrichment

If your measurement needs go beyond Google, or you require Facebook CAPI, sGTM is the correct approach.

Which One Is Right for You?

Most B2B organizations eventually adopt both, starting with Google Tag Gateway for quick gains and evolving into sGTM for advanced integrations.

Choose Google Tag Gateway if:

Your measurement is primarily within Google tools
You don’t need CRM or non‑Google ad platform integrations
You want the fastest, simplest improvement with minimal engineering

Choose sGTM if:

You want maximum flexibility and control over your data architecture
You run ads on Meta, LinkedIn, Bing, TikTok, or multiple platforms
You need Meta CAPI (requires sGTM to function properly)
You rely on CRMs, server‑side integrations, heatmapping, call tracking

Hear From Our Happy Partners

We partnered with Marcel to upgrade a complex Google Analytics account to GA4, and it truly did feel like a partnership. They were transparent with us about what was and wasn't possible, provided thoughtful answers to questions, and helped us navigate the transition smoothly. They weren't pushy about adding services, didn't have any hidden charges, and I would wholeheartedly work with them again if the need arose. Highly recommend!

I went with Marcel Digital over a larger - and much higher priced - competitor and it's one of the best decisions I've made. Marcel Digital are lovely people to deal with, extremely knowledgeable and approachable and willing to take the time to examine possible solutions that differ from how they would normally proceed. I value the partnership with their company and am planning on having our company be a client of theirs for years to come. Can't recommend them enough.
