Connect platforms
One Google sign-in covers GA4, Tag Manager and Search Console. The sign-in is read-only; write access (Google Ads changes, GTM setup) is a separate opt-in, and every change still waits for your approval.
Connect Google
- Open the Platforms page in the MarStack dashboard and click Connect Google.
- Choose the Google account that has access to your GA4 properties and GTM containers. It can be different from the email you signed up with.
- Approve the read-only permissions. You come back to Platforms with the account listed and its GA4 properties shown.
What MarStack can see
| Access | Google permission |
|---|---|
| GA4 settings and reports | analytics.readonly |
| Who has access to each GA4 property | analytics.manage.users.readonly |
| GTM containers, tags and published versions | tagmanager.readonly |
| Search Console sites and search data | webmasters.readonly |
Nothing in your accounts is ever changed. Your Google tokens are encrypted at rest and refreshed automatically.
More than one Google account
Agencies often reach client properties through different Google accounts. Connect each one: when you ask for an audit, MarStack uses whichever account can open that property or container. Free and Starter connect 1 account, Pro 3 and Agency 25.
Disconnect or reconnect
Disconnect on the Platforms page revokes MarStack's access at Google and deletes the stored tokens. If Google stops accepting a connection (for example after a password change), the account shows Reconnect and your assistant tells you which account needs it.
Coming next
Meta Ads, Google Ads, BigQuery, LinkedIn Ads and TikTok Ads connections are on the way. Website checks (tracking, consent and public GTM audits) need no connection at all.
