Frequently asked questions
Is the free plan really free forever?
Yes. SignalForge has no paid tier and no trial clock. Daily limits keep it fast and affordable to run, and they reset at midnight UTC.
What is SearchSignal Pro?
SearchSignal is our sister product for teams and AI-agent workflows. Pro costs $19.99/month and adds licensed Google Ads volume and CPC, licensed SERP data, live backlinks, 75-page audits and 2,000 searches a day, available in the web app and through MCP.
Do I need a new account for Pro?
Yes. SearchSignal Pro runs on searchsignal.pro with its own account. Create one, and you go straight to the upgrade page and Stripe Checkout.
How do I cancel Pro?
Open Settings and choose Manage billing on searchsignal.pro. The Stripe billing portal lets you cancel or download invoices yourself, at any time.
What happens when I hit a free limit?
The tool tells you which limit you reached and when it resets. Nothing is charged, and your saved lists and projects stay available.
