The delicate balance between privacy and performance
New rules. New solutions.
Browsers, regulations, and users are reshaping the digital ecosystem. Brands that want to keep measuring accurately must embrace first-party data.
Google First Party Mode is the answer: a way to tag and measure directly from your own domain, without intermediaries.


The solution: First Party Mode
Regain control from your own domain
Google has launched First Party Mode as a response to this new environment. A new way to manage Google Tag Manager, from your domain, without intermediaries.
Here’s how it works:
-
Google Tag Manager is hosted on your own servers, not on Google’s.
-
The browser reads the signal as first-party, reducing blocking and improving data quality.
-
All measurement becomes more resilient, more private, and more accurate.
Benefits for your business
Modern measurement. Real results.
More valuable data, less loss
Remove technical barriers and browser blocking. Capture more events and improve data quality to build richer audiences and more effective campaigns.
Privacy as a competitive advantage

No need for servers or complex setups. Activate First Party Mode with One Tag and adapt measurement to any stack, without slowing down campaigns.

FAQs
Got questions? At Adsmurai, we’ve got answers
-
What exactly is First Party Mode (FPM)?
First Party Mode is a new way to serve Google measurement tags (like GTM or Google Tag) directly from your own domain, instead of from Google’s servers. This improves privacy, browser compatibility, and cookie persistence.
Ad blockers, Opera, and Safari already block cookies and signals, which complicates digital marketing campaign optimization. By migrating Google Tag Manager to First Party Mode, you increase the volume and quality of your ad events.
-
Is FPM like a CAPI?
Not exactly. First Party Mode isn’t a Conversion API like Meta’s, but it shares the same goal: sending high-quality data from your domain while avoiding browser blocks. The big difference is that in Google’s case, server-side tagging happens under your domain. And if you activate it with One Tag, you don’t even need your own servers. Think of it as Google’s “native CAPI,” ready to scale without friction.
-
Is it compatible with Google Tag Manager?
Yes. First Party Mode is 100% compatible with GTM, Google Tag, and Enhanced Conversions. It’s part of Google’s official stack for cookie-less environments.
-
What if I don’t have my own infrastructure to set up the proxy?
No problem. With Adsmurai’s One Tag, you can activate FPM without your own servers. It’s preconfigured to run in First Party Mode, scalably and without technical hassle.
-
What about my Enhanced Conversions? FPM doesn’t just support them — it improves them
Since everything runs from your own domain, the signals sent to Google are cleaner and more reliable, increasing the likelihood of conversions being captured and improving attribution accuracy.
-
Does FPM slow down my website?
Quite the opposite. By reducing calls to external servers, it lowers latency, improves loading times, and enhances overall site performance.
-
What’s the implementation process like with Adsmurai?
The process is fast, transparent, and fully supported by our team. We divide it into three phases:
-
Technical diagnosis: We review your current tag setup, domain, and server/CDN.
-
Custom configuration: We adapt the data flow so that Google tags are served from your own domain (e.g. yoursite.com/tracking).
-
Testing and activation: We validate that everything works (tagging, conversions, Consent Mode compatibility, Enhanced Conversions, etc.) and guide you through the deployment.
Throughout the entire process, our Solutions team will be by your side to answer questions, coordinate with your technical teams, and ensure a smooth transition to FPM.
