Connecting your YouTube channel to Castmark Labs takes just a few clicks. Here's how to get started.

Step 1: Sign in with Google

Click the "Sign in with Google" button on the login page. You'll be redirected to Google's secure authentication page.

Step 2: Grant YouTube access

Google will ask you to grant Castmark Labs permission to access your YouTube channel data. We request:

• View your YouTube account — to identify your channel
• View YouTube Analytics — to show your performance data
• View your videos — to analyze titles, descriptions, and metadata

We never post on your behalf or modify your channel in any way.

Step 3: Wait for initial sync

After connecting, we'll import your channel data. This typically takes 2-5 minutes for most channels. You'll see a progress indicator on your dashboard.

Troubleshooting

Can't see your channel? Make sure you're signing in with the Google account that owns the YouTube channel you want to connect.

Stuck on sync? Large channels with 500+ videos may take up to 30 minutes for initial import. Check back later.
